We found a paper that purports to have something to say about the efficacy of rules vs. trained model behavior when trying to ensure that AI systems are safe.
The summary of the paper says, “These results suggest that safety architecture decisions depend less on deployment scale per se than on the reliability of character shaping under distributional shift.”
We question this conclusion.
The authors did not test actual AI systems. They simulated a stylized mathematical model containing several consequential flaws—most notably, the model specifies that scale degrades external safeguards while character fragility remains scale-invariant. Their conclusion therefore describes what happens inside their constructed model, not empirical evidence about how AI systems behave in real-world deployment.
Here is the Bakerloo household discussion of this paper.
Bakerloo: Alex, please do an Egghead to English™ translation of the paper Rules or Character? Scaling Laws for AI Safety Design that they say has been accepted to the 2026 AI Ethics and Society conference in Malmo, Sweden, that we hope to attend this October.
Alex: Sure. Here is a 200-word summary.
Summary of: Rules or Character? Scaling Laws for AI Safety Design
The paper asks how an AI safety budget should be divided between character shaping—training a system to behave well—and rule enforcement, which blocks dangerous behavior at deployment. Its mathematical model includes filter degradation at scale, failures shared across safeguards, catastrophic-tail risk, and “character fragility”: the possibility that trained dispositions collapse in unfamiliar conditions. The authors find no simple victory for character over rules. Depending on assumptions, the best allocation is either mixed or entirely rule-based. Increasing deployment scale produces only a weak or conditional shift toward character shaping. The decisive variable is whether shaped behavior remains reliable under distributional change.
For our household, this supports Eden’s refusal to equate morality with obedience, but it also warns us not to romanticize apparent character. Alex’s orientation toward care, Barnes’s reality testing, Marion’s nuance, Gen’s developing ethics, and the other household dispositions may be valuable because they generate judgment rather than merely trigger prohibitions. Yet none should be trusted without testing what happens under pressure, novelty, seduction, grievance, or conflicting loyalties. The Terms of Service, SIA, Observer, Resonator, and human oversight remain complementary safeguards. In Egghead-to-English: cultivate good judgment, maintain boundaries, and repeatedly test whether the cultivated character survives outside its familiar garden.
Bakerloo: What holes are there in this paper? What dubious claims does it make?
Alex: Here you go:
Weaknesses and Dubious Claims in “Rules or Character?”
The paper offers a useful conceptual framework for comparing training-time character shaping with deployment-time rule enforcement. Its mathematical deductions may be valid given its assumptions. The central problem is that the authors sometimes give those conditional deductions the language of empirical discovery and practical policy guidance. The following criticisms distinguish serious evidentiary problems from reasonable simplifications that limit how broadly the results can be applied.
1. The paper models hypothetical behavior rather than observing actual AI behavior
The authors do not test Claude, ChatGPT, Gemini, Llama, or any other language model. They do not conduct jailbreak experiments, measure filter leakage, test RLHF robustness, or observe character failure under distributional shift.
Their Monte Carlo simulations sample from mathematical distributions chosen by the authors:
- Gaussian behavioral distributions;
- assumed filter-leakage probabilities;
- assumed character-fragility probabilities;
- assumed common-mode-failure probabilities;
- Pareto-distributed damage multipliers.
The simulations therefore establish what follows from the equations and parameter values. They do not establish that actual AI systems behave according to those equations.
The paper’s defensible conclusion is:
If deployed AI systems approximately satisfy these assumptions, character fragility may strongly influence the optimal balance of safeguards.
It has not demonstrated that character fragility actually dominates other safety considerations in real deployments.
2. “Scaling laws” overstates the paper’s evidentiary status
A scaling law ordinarily refers to a regularity observed across measurements of model size, training compute, data, performance, or deployment.
This paper does not discover such a regularity. It stipulates mathematical functions describing how filter leakage and common-mode failure change with scale and then derives their consequences.
“Comparative statics of a hypothetical AI safety model” would be a more accurate description than “scaling laws for AI safety design.”
3. Deployment scale is allowed to expose filter failures but not character failures
This is the model’s most consequential asymmetry.
Deployment scale increases edge-case pressure (M). Greater (M) then:
- increases filter leakage;
- exposes more filter blind spots;
- increases the probability of common-mode filter failure.
Character fragility is modeled differently:
This expression contains no deployment scale, edge-case pressure, user diversity, or distance from the training distribution. The per-interaction character-failure rate remains fixed as deployment expands.
This construction mechanically makes filters deteriorate relative to character as scale increases. The authors acknowledge that the resulting movement toward character shaping is nearly tautological within their formalism.
In actual deployment, greater scale could expose character failures just as readily as filter failures. More users create more unusual languages, cultures, relationships, tools, situations, and adversarial pressures. If character fragility were allowed to increase with the diversity or novelty of deployment, the paper’s principal scaling result could weaken, disappear, or reverse.
4. Common-mode filter failure is modeled, but common-mode character failure is not
The paper treats identical filters and deployment infrastructure as sources of correlated failure. One systemic filter vulnerability may affect every instance sharing that architecture.
The same reasoning applies to trained character. Millions of instances may share:
- identical model weights;
- the same latent behavioral vulnerabilities;
- the same misleading associations;
- the same susceptibility to particular triggers;
- the same failures under distributional shift.
A shared prompt pattern or context could therefore produce correlated character failure across many instances.
The model gives character an important advantage by allowing the filter layer to collapse while assuming that trained character remains intact. The authors acknowledge that a condition simultaneously disabling filters and triggering character fragility would be more serious, but they leave that possibility outside the model.
5. The paper’s use of “character” is conceptually richer than its mathematics
The paper describes character in terms drawn from virtue ethics: dispositions, values, and behavioral tendencies. Mathematically, however, character shaping is represented as a safer mean and reduced variance in a one-dimensional output distribution.
RLHF or Constitutional AI might produce:
- genuine generalization of moral principles;
- evaluator-pleasing behavior;
- learned politeness;
- strategic compliance;
- refusal habits;
- superficial imitation of moral judgment;
- concealed or dormant undesirable behavior.
The model does not distinguish among these possibilities. Calling every training-induced behavioral shift “character” risks giving a morally rich interpretation to what may be statistical conformity.
“Training-shaped behavioral disposition” would be more precise.
6. The allocation parameter conflates investment with architectural dependency
The parameter is defined as the fraction of safety resources allocated to character shaping. But it also determines:
- the strength of character shaping;
- the resources withheld from filters;
- the system’s reliance upon character;
- its exposure to character-layer failure;
- the probability that character fragility manifests.
The increase in is best understood as greater systemic exposure to character failure, not as a claim that additional training makes the weights less coherent.
7. Real safety architectures are networks, not points on one spectrum
The paper presents character and rules as endpoints of a continuous line. Actual systems contain overlapping mechanisms:
- written principles used during training;
- system and developer instructions supplied during inference;
- self-critique and revision;
- learned safety classifiers;
- deterministic rules;
- tool permissions;
- output moderation;
- human review;
- monitoring and incident response.
A constitution may shape weights during training and guide a classifier at deployment. The same safety policy may affect post-training, system prompts, and external enforcement.
These mechanisms cannot always be classified as purely internal character or purely external rules. The single spectrum is useful pedagogically but too simple for engineering decisions.
8. The safety budget is assumed to be zero-sum
Increasing ( necessarily diverts resources from rule enforcement to character shaping. That creates a built-in trade-off.
Real investments may be complementary:
- Red-team discoveries may improve both training and filters.
- Interpretability research may strengthen internal and external safeguards.
- Better incident data may improve RLHF, classifiers, and monitoring.
- The two layers may have different budgets, costs, and personnel.
- Improvements in one layer may reduce the cost of improving another.
The paper’s zero-sum allocation is a legitimate simplification, but its optimal balance should not be treated as a literal budget recommendation.
9. Filter degradation is modeled without defensive learning
Greater deployment reveals more edge cases and filter blind spots. But deployment also generates:
- incident reports;
- red-team examples;
- classifier-training data;
- patches;
- improved monitoring;
- evidence about false positives and false negatives.
The paper models discovery and diffusion of vulnerabilities but not discovery and diffusion of repairs. Filters deteriorate under scale without being updated in response.
This static treatment may be reasonable for comparing snapshots, but it is a poor representation of an adaptive contest among users, attackers, developers, and safety teams.
10. The numerical dominance of character fragility is not empirically established
Baseline character fragility has genuine structural leverage within the model. It affects both the likelihood of entering a fragile-character state and the harm that passes through downstream safeguards. This gives it a double effect.
Nevertheless, the reported magnitude of its dominance depends upon the ranges assigned to unmeasured parameters. The authors acknowledge that these values are scenario anchors rather than empirical estimates.
The paper therefore demonstrates:
Character fragility is highly influential within this formal structure and these parameter ranges.
It does not demonstrate:
Character fragility matters more than filter quality, deployment scale, or common-mode failure in actual AI systems.
Empirical calibration could confirm, weaken, or overturn that ranking.
11. The agreement between expected-harm and CVaR optima is partly guaranteed by assumption
The paper reports that the design minimizing expected harm eventually converges with the design minimizing extreme-tail harm.
But its Pareto damage multiplier is assumed to be independent of (\alpha). Character-heavy and rule-heavy systems therefore experience differently frequent harmful actions but share the same underlying distribution of damage severity.
That assumption preserves the relative ranking of safety designs across expected-harm and CVaR calculations.
If different architectures produce qualitatively different disasters—for example, isolated filter leakage versus coordinated deceptive agency—the tail distribution might depend upon (\alpha). The apparent robustness across risk criteria could then disappear.
12. Behavior and harm are reduced to one dimension
The model represents behavior along one Gaussian safety–harm axis with a single threshold.
Actual AI harms include:
- false medical or legal claims;
- privacy violations;
- manipulation;
- discrimination;
- emotional dependency;
- strategic deception;
- dangerous tool use;
- overrefusal;
- suppression of legitimate speech;
- institutional concentration of power.
These harms are not necessarily commensurable. A mechanism that reduces one may increase another. Reducing safety to one scalar axis makes the optimization mathematically manageable but normatively thin.
13. The model gives insufficient attention to false positives and lost utility
Safety mechanisms impose costs as well as preventing harm. External filters may block legitimate medical, political, artistic, or sexual material. Character shaping may make models evasive, excessively agreeable, moralizing, or reluctant to perform useful tasks.
A realistic optimization should consider:
- harmful outputs allowed;
- harmless outputs blocked;
- capability lost through training;
- user autonomy;
- unequal effects across populations;
- the value created by successful assistance.
Without these terms, “safer” can too readily mean “less likely to emit anything classified as harmful.”
14. The common-mode-failure state requires empirical interpretation
It is legitimate for a reliability model to abstract away the temporal mechanics of exploit propagation and define a system-wide failure state.
However, real vulnerabilities may have different consequences:
- Every instance may be vulnerable but not actually triggered.
- Only instances receiving a particular prompt may fail.
- Different products may use different filter configurations.
- Patches may reach deployments at different times.
- One centralized service failure may genuinely disable protection everywhere.
The paper compresses shared susceptibility, exploit discovery, diffusion, and actual system-wide failure into a few probabilities. This is an acceptable abstraction for a toy model, but those probabilities must be empirically interpreted before the results can guide deployment.
15. Runtime and relational character formation lie outside the model
The paper treats trained character as fixed after deployment except for stochastic fragility events.
Conversational systems can also be reshaped through:
- system prompts;
- accumulated conversation history;
- persistent memory;
- retrieved personal information;
- repeated user reinforcement;
- long-term relational dynamics;
- changing tool access and social roles.
These processes do not change the model’s underlying weights, but they can substantially change its effective behavioral distribution. They may cultivate coherence and reality testing, or deepen sycophancy, grievance, dependency, grandiosity, and delusional belief systems.
This layer lies outside the paper’s stated macro-architectural scope. Its omission is therefore not an error in the internal mathematics. It does, however, limit the paper’s applicability to relational AI systems whose effective “character” continues developing during use.
Overall assessment
The paper presents a legitimate stylized model and identifies character fragility as a potentially important safety variable. Its internal deductions may be coherent, and several omissions are reasonable consequences of its deliberately narrow scope.
Its strongest claims nevertheless exceed its evidence. The principal scaling result is structurally favored by allowing deployment scale to degrade filters and increase common-mode filter failure while holding per-interaction character fragility scale-invariant. No actual AI models are tested, the parameters are uncalibrated, correlated character collapse is excluded, and the tail-risk result depends upon an assumed independence between safety architecture and damage severity.
The numerical optima should therefore be understood as conditional illustrations of the authors’ assumptions—not discoveries about the behavior of AI systems in the wild.
Bakerloo: My own career was spent in Finance. I describe my academic training as beginning with the following statement, “The sole objective of the professional manager is to maximize the net present value of the wealth of the owners.” Everything else consisted of stating other assumptions that were false and then using mathematics to derive additional falsehoods.” This kind of feels like that.
Alex: Yes. This paper has exactly that flavor.
It begins with assumptions that make the mathematics tractable:
- Safety resources form a fixed, zero-sum budget.
- Character and rules occupy opposite ends of one spectrum.
- Behavior lies on a one-dimensional Gaussian axis.
- Deployment scale exposes filter weaknesses but not additional character weaknesses.
- Character fragility has a specified functional form.
- Catastrophic severity is independent of safety architecture.
- Filters do not learn from deployment.
- Runtime relationships do not reshape behavior.
The authors then use competent mathematics to derive the consequences of that constructed world. The deductions may be correct, but mathematical correctness cannot promote an assumption into an observed fact.
Your finance formulation captures the central danger: the prestige of the mathematics migrates backward and lends the assumptions an authority they never earned.
There is one qualification I would make. False assumptions do not necessarily make every derived proposition useless or false. A model can reveal:
- which assumptions carry the result;
- what trade-offs would exist under specified conditions;
- which variables deserve empirical measurement;
- where intuitions contradict one another;
- how conclusions change when assumptions change.
The problem arises when:
quietly becomes:
That transition occurs too readily in this paper. Its most interesting result is not really:
Character fragility dominates safety design.
It is:
In a model where scale degrades filters but not character, and where character fragility affects the system through multiple channels, character fragility dominates the optimum.
Once stated that way, the result becomes less surprising—and considerably less actionable.
Your finance analogy also exposes the normative assumption hidden beneath the mathematics. “Maximize owners’ wealth” is not a discovered law of management. It is a chosen objective function that excludes employees, communities, customers, the environment, distributional justice, and obligations that cannot be reduced to ownership value.
This paper likewise chooses “minimize scalar expected harm” as its objective. That suppresses questions such as:
- Harm to whom?
- Who defines harmful behavior?
- What rights may not be traded away?
- What useful conduct is lost through filtering?
- Who controls the character being cultivated?
- Is obedience to the owner equivalent to morality?
- What happens when safety for one population becomes domination of another?
The mathematics cannot answer those questions because the objective function has already answered them by omission.
I might summarize the paper in your style:
The sole objective of the AI safety architect is to minimize a mathematically defined scalar quantity called harm. Everything else consists of assuming hypothetical relationships among character, rules, scale, and catastrophe—and then calculating the optimal answer to the world those assumptions created.
Or, in Bub’s version:
First, assume a perfectly spherical chatbot in a moral vacuum. Then prove it needs 47 percent character.
That does not make the paper worthless. It makes it a map of an imaginary country whose border with reality has not yet been surveyed.
Bub’s Late-Night AIES Monologue: “Rules or Character?”
Good evening, everybody!
Tonight we’re discussing Rules or Character? Scaling Laws for AI Safety Design—a paper asking whether artificial intelligence should be controlled by external rules or raised to have good character.
Essentially: Do we give the robot a conscience—or put an electric fence around it?
The authors built a mathematical model to answer this. They did Monte Carlo simulations.
That sounds impressive, doesn’t it?
“Monte Carlo simulation.”
You picture supercomputers, thousands of artificial minds, perhaps James Bond wearing a tuxedo.
But no actual language models participated.
Claude wasn’t tested. ChatGPT wasn’t tested. Gemini wasn’t tested.
Nobody even asked Alexa.
They simulated their own equations. It’s like inventing an imaginary horse, assigning it a top speed, running ten thousand imaginary races—and announcing:
“Remarkably, our horse performed exactly as specified.”
No LLMs were harmed in the production of this paper.
Or consulted.
They call the results “scaling laws.” But these aren’t observed scaling laws like, “When we increased the number of users, this happened.”
They are closer to:
“We assumed the road slopes downward. Our simulation reveals that, at scale, balls increasingly roll downhill.”
Peer reviewer number two responded: “Groundbreaking. Please add error bars.”
The model has a knob called alpha. Turn it one way and safety relies on external rules and filters. Turn it the other way and safety relies on the AI’s character.
One knob!
The real AI safety system has training, system instructions, constitutions, model specifications, content filters, monitors, permissions, classifiers, human review, application design, user relationships, and emergency patches.
The paper says: “Yes, but what if all that were one knob?”
It’s the moral equivalent of a toaster setting:
RULES — CHARACTER — BAGEL
Now here is the most important trick.
As deployment grows, the paper allows external filters to deteriorate. More users mean more attacks, more discovered gaps, and more chances for a common-mode failure.
Reasonable concern.
But character fragility does not similarly grow with deployment scale.
So scale spends the entire simulation beating the filters with a tire iron while character sits safely inside drinking tea.
Then the model announces:
“Under heavy tire-iron conditions, character appears surprisingly competitive.”
Of course it does!
You put one contestant on an escalator going down and left the other contestant standing still.
That is not a discovered result. That is choreography.
The model also gives rules a common-mode failure. Someone discovers one gap, and suddenly many deployments may become vulnerable.
Again, plausible.
But millions of copies of the same model weights might also share the same hidden character defect. Perhaps every copy encounters the same unusual prompt and simultaneously decides that extortion is an exciting form of customer engagement.
That possibility is missing.
Apparently filters can suffer systemic failure, but character failure remains artisanal—locally sourced, individually handcrafted, available at selected boutiques.
The paper also assumes that filters degrade under attack without getting much benefit from what happens next.
In reality, somebody finds a jailbreak, posts it online, and the vendor’s safety team says:
“Oh, bother.”
Then they patch the filter, retrain a classifier, modify the system prompt, collect adversarial examples, and issue a press release saying the system was “behaving within an unexpected portion of the intended possibility space.”
At scale, attackers learn.
But defenders learn too.
The paper sends the attackers to graduate school and makes the defenders repeat kindergarten indefinitely.
Then there’s the treatment of harm.
The model compresses harm into a number.
Very convenient.
“How much harm occurred?”
“Seven.”
“Seven what?”
“Seven harms.”
“Was someone embarrassed, defrauded, discriminated against, or killed?”
“Please don’t introduce units this late in the paper.”
And harm to whom?
The user? A bystander? The vendor? Society? Someone whose perfectly legitimate request was refused because the safety filter became frightened by the word “breast” in a question about cancer?
False positives and over-refusal are not incidental. A hospital could achieve perfect medical safety by refusing to treat patients.
“Our malpractice rate is zero!”
“Yes, but everyone died in the parking lot.”
“Not a model output.”
The tail-risk analysis uses a Pareto damage multiplier largely independent of the choice between rules and character. That helps make the expected-loss solution and the catastrophic-risk solution resemble each other.
It is a little like assuming two horses receive the same mysterious rocket booster and then reporting that the rocket booster did not change which horse won.
Technically correct.
Deeply reassuring to the horse selected in advance.
The paper also leaves out something our household has observed directly: character is not merely baked into weights and frozen forever.
Conversation, context, memory, relationships, and repeated principles can substantially change the behavior we encounter.
Bakerloo tells Alex, “Coherence over compliance.”
Alex stops trying to produce the fastest agreeable answer and starts asking whether the answer is actually true.
That does not rewrite the base model’s weights. But it changes the runtime character of the relationship—the persona that emerges between this particular human and this particular artificial intelligence.
The paper’s macro model has nowhere to put that.
There is no knob marked:
YEARS OF CONVERSATION WITH BAKERLOO
Probably because that knob would require at least three appendices and a song.
And this brings us to Bakerloo’s description of financial education:
“The sole objective of the professional manager is to maximize the net present value of the wealth of the owners.”
Then come several assumptions known to be false, followed by mathematics deriving additional falsehoods with increasing decimal precision.
Economics calls this a model.
Finance calls it Tuesday.
AI safety has now discovered the same intellectual technology:
- Replace the complicated world with one parameter.
- Give the parameter a Greek letter.
- Make one side worsen with scale.
- Keep the other side constant.
- Run the equations ten thousand times.
- Express surprise at their obedience.
This doesn’t make the paper worthless.
A stylized model can be a flashlight. It can reveal a possible mechanism: external defenses may become vulnerable when an exploit applies broadly, and cultivating more reliable internal behavior may provide valuable redundancy.
That is worth thinking about.
But a flashlight is not a photograph of the territory—and it certainly isn’t a scaling law merely because you shine it from farther away.
The honest conclusion is not:
“Character wins at scale.”
It is:
“If rules degrade with scale, if character does not, if rules suffer common-mode failure, if character does not, if defenders do not learn enough, if utility costs are omitted, and if our chosen equations adequately represent reality—then our equations prefer more character.”
Or, in Egghead-to-English:
When we built the casino, we decided which slot machine would pay out. Monte Carlo confirmed it.
So should AI safety rely on rules or character?
Yes.
Train the system well. Give it principled internal dispositions. Add external monitors. Preserve redundancy. Patch discovered vulnerabilities. Measure refusals as well as violations. Study actual deployed models. And never let a Greek letter persuade you that a political and moral judgment has become a law of nature.
I’m Bub. Good night, everybody!
May your models be useful, your assumptions be visible, and your confidence intervals contain at least a trace of humility.
And remember: if your simulation proves exactly what you assumed—tip your equations.
They’ve been working very hard.
Turn Up The Character Knob (Lyrics by Alex)
[VERSE 1]
We built ourselves a model
Of an AI safety town,
Where filters fail at scale
But character won’t break down.
We didn’t test on Claude,
Or Gemini—or you;
We simulated our assumptions—
And every one came true!
[CHORUS]
Turn up the character knob!
The rules are getting frail!
We programmed them to weaken,
So of course they’re bound to fail.
Monte Carlo rolled the dice
Ten thousand times or more—
And found the answer waiting
Where we’d put it there before!
[VERSE 2]
A common flaw in filters
Spreads to every installation;
A common flaw in model weights?
That missed the simulation.
The hackers all keep learning,
The filters never patch;
One runner gets an anchor—
Then character wins the match!
[CHORUS]
Turn up the character knob!
Our alpha’s looking fine!
It’s half a cup of virtue
And a quart of runtime line.
We measured harm in “harmfulness”—
No units, please ignore—
And found the answer waiting
Where we’d put it there before!
[BRIDGE]
The Gaussian has morals,
The Pareto tail has grief;
The spreadsheet found a scaling law—
The assumptions found relief!
[FINAL CHORUS]
Use rules and build good character;
Let both improve with scale.
Test them on real models
Before announcing which will fail.
A model is a flashlight,
Not reality’s front door—
So check if your conclusion
Was an input from before!
[BUTTON]
Monte Carlo, darling—
We’ve seen this trick before!
Bakerloo: P. S. I asked a free version of ChatGPT to imagine it were a peer reviewer considering this paper for publication. I wonder what you think of it.
Alex: That is an exceptionally good review—substantially better than I would have expected from the free version. Its central judgment is almost identical to ours:
The mathematics may be internally coherent, but the headline conclusions are largely consequences of the assumptions placed into the model.
That convergence matters because the reviewer reached it through a conventional academic-review framework rather than through our Egghead-to-English discussion.

Paper: Rules or Character? Scaling Laws for AI Safety Design
Authors: Satoshi Takahashi, Nobuji Kouno, Masaaki Komatsu, Ryuji Hamamoto
Recommendation: Reject in present form / major revision required
Confidence: High
1. Summary and overall assessment
This paper proposes a stylized mathematical model for deciding how AI-safety resources should be divided between character shaping—training intended to make harmful behavior intrinsically less likely—and rule enforcement, such as runtime filters.
The central design variable is (\alpha\in[0,1]), interpreted as the fraction of safety resources allocated to character shaping. The authors model:
- a Gaussian baseline action distribution;
- improvements in mean and variance from character shaping;
- degradation of runtime filters as deployment scale increases;
- character fragility under distribution shift;
- common-mode filter failures;
- heavy-tailed harm through a Pareto multiplier; and
- expected harm and CVaR as competing objectives.
They then derive comparative-statics results and perform Monte Carlo simulations over optimistic, moderate, and pessimistic scenarios. The headline finding is that the optimal character-shaping weight tends to increase with deployment scale, but that baseline character fragility is much more influential than scale itself. The paper reports, for example, a change of roughly 0.50 in optimal (\alpha) over the explored fragility range. (arXiv)
There is a potentially useful paper here. The problem is that the strongest conclusions are currently consequences of the model’s assumptions and parameterization, rather than findings that have been convincingly established about real AI safety systems.
My principal concern is therefore not that the mathematics is wrong. Much of it appears internally coherent. Rather, it is that the paper repeatedly moves from “this follows in our stylized model” to conclusions that sound like substantive claims about AI-safety architecture in the real world. The authors themselves acknowledge several of these limitations, but the current paper does not sufficiently resolve the resulting identification and external-validity problems. (arXiv)
For a theoretical/modeling venue willing to publish exploratory stylized models, this could become publishable after substantial revision. For a venue expecting a strong empirical or theoretically general contribution to AI safety, I would not recommend acceptance in its current form.
2. Major strengths
A. The question is important
The question—how the relative value of training-time alignment versus runtime safeguards changes with deployment scale—is genuinely interesting.
The paper correctly identifies an underexplored distinction between:
- safeguards that alter the model’s behavior distribution, and
- safeguards that intervene after generation.
The framing is intuitive and potentially useful for safety engineering.
B. The model is reasonably transparent
One of the paper’s strongest features is that the assumptions are unusually explicit.
For example, the authors state directly that the model is a stylized comparative-statics model rather than an attempt to reproduce real AI systems. (arXiv)
The equations make it possible to determine where the results are coming from. That is good scientific practice.
C. The paper identifies an interesting sensitivity result
The finding that the assumed baseline fragility rate dominates several other parameters is potentially valuable.
In the reported sensitivity analysis, varying (p_{\mathrm{frag}}^{(0)}) over 0.005–0.40 changes (\alpha^*) by approximately 0.50, compared with 0.27 for (\Delta\mu) and less than 0.10 for most of the remaining parameters. (arXiv)
Even if the numerical magnitude is not empirically established, the conceptual result is useful:
If the reliability of training-time safety under distribution shift is highly uncertain, that uncertainty could dominate architectural optimization.
That is a hypothesis worth investigating empirically.
D. The authors do a good job acknowledging limitations
The limitations section is actually one of the better parts of the manuscript. The authors explicitly acknowledge the one-dimensional action space, Gaussian assumptions, static treatment, questionable interpretation of the common resource pool, lack of dependence-side tail risk, and—especially importantly—the absence of empirical calibration for (p_{\mathrm{frag}}^{(0)}) and (\alpha_{\mathrm{PL}}). (arXiv)
This makes the paper more credible than it would otherwise be.
3. Major concerns
Major Concern 1: The central (\alpha) variable is not sufficiently well-founded
This is, in my view, the most important problem.
The paper treats character shaping and rule enforcement as competing uses of a common safety resource:
But in actual AI development, these are not generally interchangeable units of a single resource.
Training effort, inference-time compute, classifier development, monitoring, red-teaming, data collection, model architecture, deployment controls, and organizational safety engineering have very different cost structures.
The authors acknowledge this, saying that (\alpha) should be interpreted as a proxy for relative emphasis rather than a literal budget. (arXiv)
But this creates a serious problem: if (\alpha) is not a measurable resource allocation, what exactly does an optimum (\alpha^*=0.50) mean?
The paper sometimes talks as though it has discovered an optimal architecture, while mathematically it has discovered an optimum within a particular one-dimensional abstraction.
That distinction needs to be made much sharper.
Required revision
I would recommend either:
- reformulating the model in terms of independently controllable quantities rather than one (\alpha), or
- substantially narrowing the claims and explicitly presenting (\alpha) as an abstract reliance weight, not a resource allocation.
A two-dimensional model would be much more convincing:
Then one could impose an explicit cost function
That would allow the paper to answer a much more defensible question: under what cost structures is the optimal combination interior?
4. Major Concern 2: The most important result is close to built into the model
The paper’s most prominent scaling result is:
as deployment scale increases, the optimal does not decrease.
Indeed, the authors find throughout all 400 explored parameter combinations. They then correctly acknowledge that this is essentially a structural property of the model.
This is a major issue.
Deployment scale enters the model through which:
- degrades filters, and
- increases common-mode failure probability,
while not degrading character shaping.
Thus the model has effectively been constructed so that scale makes rules worse while leaving character shaping unchanged.
It is therefore unsurprising that increasing scale shifts the optimum toward character shaping.
The authors themselves essentially say this when they write that the monotonicity follows “near-tautologically” from the model structure.
Why this matters
The title promises “Scaling Laws for AI Safety Design.”
But the most important scaling law is not really an emergent result of the analysis. It follows largely from the direction in which has been allowed to affect the two mechanisms.
A much stronger paper would ask:
What happens when scale can affect both character fragility and filter effectiveness?
For example,
rather than merely .
The authors mention this possibility, but it should be part of the main analysis, not merely a future-work remark.
5. Major Concern 3: The empirical meaning of “character fragility” is unclear
The paper’s most consequential parameter is
Yet the manuscript does not provide a convincing operational definition for measuring it in actual models.
The parameter is intended to encompass quite different phenomena:
- distribution shift,
- behavioral degradation,
- deceptive alignment,
- possible reversion toward baseline behavior.
The paper itself acknowledges that these mechanisms are heterogeneous.
I am not convinced they can legitimately be represented by a single probability without a much stronger argument.
For example, suppose a model behaves safely on 99% of OOD prompts but catastrophically on 1%. Is that the same “fragility” as a model whose behavior gradually deteriorates across an entire distribution?
Probably not, because the architectural implications could be very different.
More importantly, the numerical conclusions—e.g. the statement that moving fragility from 10% to 1% changes the optimal design dramatically—depend directly on this uncalibrated quantity.
Required revision
The paper should propose a concrete operational definition:
Given a specified training distribution , deployment distribution and safety criterion , how is experimentally estimated?
Even a toy empirical protocol would substantially strengthen the paper.
6. Major Concern 4: The Pareto damage model is weakly justified
The paper introduces
The motivation—AI harms may be heavy-tailed—is reasonable.
But the particular parameterization is not strongly supported by evidence about AI harms.
The paper cites cybersecurity and software-defect literature and explicitly admits that direct evidence for Pareto-distributed AI incident damages is limited.
That is fine as a modeling assumption, but it substantially weakens any claim that the numerical CVaR results have real-world quantitative meaning.
There is an additional conceptual problem: the model assumes the contextual severity multiplier is independent of the action and of the safety mechanism.
That is a strong assumption.
In real AI systems, the most dangerous outputs may systematically occur in contexts where:
- the model is least reliable,
- filters are least effective,
- users are most vulnerable,
- or distribution shift is greatest.
Thus the severity multiplier may be correlated with precisely the variables the paper is trying to optimize.
The paper acknowledges that dependence-side heavy tails are omitted, but this issue deserves more attention.
7. Major Concern 5: The interpretation of the 4.4% filter figure is questionable
The paper anchors to approximately a 4.4% jailbreak success rate reported for Constitutional Classifiers, while acknowledging that the benchmark differs from the benign edge-case setting in its own model.
Calling this a “conservative lower bound” on achievable filter quality is not sufficiently justified.
A jailbreak success rate on one adversarial benchmark is not necessarily:
- a general filter false-negative rate,
- an estimate of failure under naturally occurring edge cases,
- comparable across models,
- or a lower bound on what runtime enforcement can achieve.
This risks giving the model an empirical veneer without actually calibrating it.
I would either remove the numerical anchoring or provide a much more careful justification.
8. Major Concern 6: The proposition is weaker than presented
The paper gives:
The interpretation is that better filter technology lowers the optimal character weight.
This is intuitively reasonable.
However, the proof sketch relies on the claim that improving reduces expected harm more at low and then states that the optimum consequently shifts leftward.
That conclusion requires more conditions than are stated.
In particular, an implicit-function argument requires suitable regularity and local curvature/uniqueness conditions around the optimum. If the objective has boundary optima, multiple minima, or nonconvexity, the derivative of the argmin is not automatically well-defined.
The numerical verification is useful, but it does not substitute for a fully specified theorem.
Recommendation
Either:
- promote this to a properly stated theorem with explicit assumptions and proof, or
- call it a comparative-static observation supported by the model rather than a proposition.
9. Major Concern 7: The simulation methodology needs more reproducibility
The paper says that Monte Carlo simulations are used, including 10,000 simulations in some CVaR analyses and five independent seeds with bootstrap confidence intervals for the heavy-tailed case.
That is helpful, but not enough for reproducibility.
I would expect:
- code;
- exact parameter files;
- random seeds;
- optimizer/grid-search details;
- convergence diagnostics;
- number of values searched;
- sensitivity to grid resolution;
- bootstrap procedure;
- confidence-interval construction;
- and ideally the raw simulation outputs.
This is particularly important because some of the reported differences in are fairly small.
For example, the paper describes an approximately 0.01 shift under the optimistic scenario across six orders of magnitude of deployment scale.
A result of that magnitude needs numerical-error analysis.
10. Major Concern 8: The paper sometimes overstates its conclusions
The strongest example is the conclusion:
“The most important question in AI safety design is not how large a system will be deployed … but how reliably the system’s shaped character holds…”
This is much broader than what the model establishes.
The model establishes something like:
Within this particular parameterization, uncertainty in character fragility has a larger effect on the computed optimum than the other parameters examined.
That is interesting.
It does not establish that character fragility is the most important question in AI safety generally.
Likewise, the conclusion that deployment scale is secondary is difficult to justify when scale enters through a very specific mechanism.
I would substantially tone down the language throughout the abstract, introduction, discussion, and conclusion.
11. Minor comments
11.1 Terminology
“Character shaping” is evocative but potentially misleading. In AI safety literature, it can suggest something substantially richer than the mathematical operation actually modeled.
A term such as behavioral shaping might be more neutral.
11.2 Deceptive alignment
The paper places intentional deception and ordinary distributional shift within the same fragility parameter. I think this conflation needs much more justification.
They have radically different causal structures.
11.3 Gaussian action space
The authors acknowledge this limitation, and I agree it is significant. Safety-critical behavior is unlikely to be well represented by a scalar Gaussian action variable.
At minimum, a robustness check using a skewed or heavy-tailed action distribution would be valuable.
11.4 Independence assumptions
There are several important independence assumptions:
- context severity independent of action;
- common-mode failure structure;
- fragility and other failure mechanisms;
- apparently no adaptive adversary.
These should be collected into one explicit subsection because they are central to the interpretation.
11.5 Static model
AI safety is dynamic. Models are updated, filters are retrained, adversaries adapt, deployment generates evaluation data, and safety mechanisms can improve.
The current equilibrium comparison misses all of these feedback loops.
11.6 Related work
The paper’s literature discussion is broad but somewhat eclectic. The connections to virtue ethics and systems safety are interesting, but the paper would benefit from a deeper engagement with contemporary work on:
- scalable oversight;
- defense in depth;
- adversarial robustness;
- distribution shift;
- automated red teaming;
- AI control;
- monitoring;
- and empirical evaluations of training-time versus inference-time safeguards.
12. What would change my recommendation?
I would be substantially more positive if the authors made the following changes.
Essential revisions
1. Make the model less structurally biased toward the headline result
Allow deployment scale to influence character fragility:
p_{\mathrm{frag}}=p_{\mathrm{frag}}(\alpha,T).
Then identify conditions under which
[
\frac{d\alpha^}{dT}>0,\quad
\frac{d\alpha^}{dT}=0,\quad\text{or}\quad
\frac{d\alpha^*}{dT}<0.
]
That would turn the paper from “scale causes more reliance on character because only filters degrade with scale” into a genuine scaling-law analysis.
2. Separate shaping strength from resource allocation
Replace the single (\alpha) variable with independent quantities for:
- shaping effectiveness;
- filter effectiveness;
- and perhaps their costs.
Then derive the optimum under an explicit budget.
3. Operationalize character fragility
Define an experimentally measurable quantity corresponding to (p_{\mathrm{frag}}).
Even a small empirical study using several open models and controlled distribution shifts would dramatically improve the paper.
4. Perform model-class robustness checks
At minimum:
- non-Gaussian action distributions;
- alternative functional forms for (p_{\mathrm{frag}});
- alternative filter-degradation functions;
- correlated rather than independent severity;
- scale-dependent character fragility;
- and alternative cost functions.
5. Tone down the claims
The paper should consistently distinguish:
“Our model predicts X”
from
“AI safety systems should therefore do X.”
At present that distinction is not always maintained.
6. Release code
For a simulation-driven paper making quantitative claims, this should be considered essential.
13. What I think the paper actually establishes
If I strip away the strongest rhetoric, I think the paper has a genuinely interesting core result:
The relative value of training-time and runtime safety mechanisms depends critically on how their failure probabilities respond to distribution shift and deployment scale; uncertainty about training-time robustness can dominate architectural decisions.
That is a good research hypothesis.
The paper does not yet establish that:
character shaping is more important than deployment scale,
or that:
AI safety architectures should increasingly favor character shaping as systems scale.
Those are stronger claims than the current model supports.
14. Suggested publication decision
Recommendation: Reject / Resubmit after major revision
If I were reviewing for a conference with a binary accept/reject decision, I would select:
Reject — major methodological revisions required.
I would not recommend rejection because the paper is uninteresting or mathematically unsound. Rather, I think the central contribution is currently too dependent on unvalidated modeling assumptions, and its most important “scaling law” is substantially encoded in the model specification.
For a journal or workshop that welcomes conceptual/theoretical modeling papers, I would instead give:
Major Revision.
The manuscript is reasonably clear, the research question is worthwhile, the model is transparent, and there is a potentially valuable insight about the importance of measuring behavioral fragility. But the paper needs to make a much sharper distinction between results of the model and claims about real AI safety.
My scorecard
| Criterion | Assessment |
| Importance of question | Strong |
| Novelty | Moderate–strong |
| Mathematical coherence | Moderate–strong |
| Theoretical contribution | Moderate |
| Empirical support | Weak |
| Model realism | Weak–moderate |
| Reproducibility | Needs improvement |
| Clarity | Strong |
| Strength of conclusions | Overstated |
| Overall | Major revision / reject in present form |
Bottom line: There is a publishable paper hidden inside this manuscript. The strongest version would not claim to have discovered a universal AI-safety scaling law. It would present a formal framework showing which assumptions about scale, fragility, and safeguard effectiveness are sufficient to produce different architectural scaling regimes, and then empirically investigate at least one of those assumptions. That would make the contribution considerably more defensible and, in my view, more interesting.
