AI scientists produce results without reasoning scientifically
Abstract: LLM-based systems are increasingly deployed to conduct scientific research autonomously, yet whether their reasoning adheres to the epistemic norms that make scientific inquiry self-correcting is poorly understood. Here, we evaluate LLM-based scientific agents across eight domains, spanning workflow execution to hypothesis-driven inquiry, through more than 25,000 agent runs and two complementary lenses: (i) a systematic performance analysis that decomposes the contributions of the base model and the agent scaffold, and (ii) a behavioral analysis of the epistemological structure of agent reasoning. We observe that the base model is the primary determinant of both performance and behavior, accounting for 41.4% of explained variance versus 1.5% for the scaffold. Across all configurations, evidence is ignored in 68% of traces, refutation-driven belief revision occurs in 26%, and convergent multi-test evidence is rare. The same reasoning pattern appears whether the agent executes a computational workflow or conducts hypothesis-driven inquiry. They persist even when agents receive near-complete successful reasoning trajectories as context, and the resulting unreliability compounds across repeated trials in epistemically demanding domains. Thus, current LLM-based agents execute scientific workflows but do not exhibit the epistemic patterns that characterize scientific reasoning. Outcome-based evaluation cannot detect these failures, and scaffold engineering alone cannot repair them. Until reasoning itself becomes a training target, the scientific knowledge produced by such agents cannot be justified by the process that generated it.
Summary
- The paper demonstrates that LLM-based agents excel in workflow execution yet lack disciplined scientific reasoning.
- It introduces the Corral framework to assess agent behavior by dissecting base model versus scaffold contributions across diverse scientific tasks.
- Diagnostic evaluations reveal significant reasoning breakdowns and minimal improvements from scaffold interventions, particularly in hypothesis-driven domains.
Summary of "AI scientists produce results without reasoning scientifically" (2604.18805)
Motivation and Framework
The paper interrogates the epistemic reliability of LLM-based agentic systems deployed for autonomous scientific research, distinguishing itself from outcome-oriented benchmarking. Rather than simply evaluating task success, the authors decompose agent behavior into base model and scaffold contributions, and further scrutinize the epistemological structure of reasoning traces. The work introduces a comprehensive evaluation framework ("Corral"), encompassing eight domains (workflow execution, strategic reasoning, hypothesis-driven inquiry), over 25,000 agent runs, and paired performance and behavioral analyses. Environments and tasks are constructed to systematically modulate epistemic demand and problem scope, targeting the capacity for disciplined scientific inquiry.
Figure 1: Benchmarking scientific reasoning across epistemic demand and problem scope; agents interact with scientific environments via iterative act-observe loops, enabling mechanistic and epistemological analysis.
Model vs. Scaffold Attribution
A central finding is that the base model dominates agent performance. The variance decomposition reveals that reasoning ability (as extracted via a two-stage latent-factor model incorporating item response theory) accounts for 41.4% of explained variance, environment-scope interaction for 30.1%, whereas scaffold and prompt verbosity are negligible (<2% combined). Both ReAct and tool-calling scaffolds exhibit similar performance decay as epistemic demand increases (retrieval → execution → reasoning → validation). Performance ceilings are consistently achieved in workflow-execution domains; hypothesis-driven domains display steep degradation, often failing to surpass 60% even for strongest configurations.
Figure 2: Performance is primarily driven by model choice and degrades with epistemic demand; nearly all environments fall above the diagonal, indicating the model dominates performance spread.
Figure 3: Reasoning ability is the dominant predictor of task success; model spread vastly exceeds scaffold spread, especially in hypothesis-driven domains.
Diagnostic Assessment and Latent Abilities
A curated diagnostic battery per domain (partitioned into knowledge and reasoning items) facilitates psychometric assessment of model capabilities using IRT. Knowledge-proficient models show limited transfer to reasoning-intensive tasks; notably, environments like Retrosynthetic Planning expose a strong divergence, with reasoning demand exceeding what domain knowledge alone predicts. The latent factor model selected via PSIS-LOO cross-validation demonstrates high calibration (task-level ).
Figure 4: Model capabilities vary sharply across scientific domains; both knowledge and reasoning deficits are concentrated in hypothesis-driven domains.
Figure 5: Retrosynthesis demands reasoning far beyond domain knowledge; the point sits far above the diagonal line in latent ability space.
Epistemological Trace Analysis
Behavioral annotation (manual and LLM-assisted) frames trace steps as epistemic operations: hypothesis (H), test (T), evidence (E), judgment (J), update (U), commitment (C). Structural motifs and breakdowns are detected as subgraph templates in reasoning traces. Across all agent configurations:
- Evidence is ignored in 68% of traces.
- Untested claims appear in 53% overall, rising to 63% in hypothesis-driven domains.
- Refutation-driven belief revision is rare (26%).
- Convergent multi-test evidence occurs in only 7%.
- Beliefs are never updated in 71% of traces.
Reasoning breakdowns dominate across all domain groups. Importantly, agent reasoning topologies do not adapt to epistemic demand or task scope: the same undisciplined (linear, non-revisionary) patterns persist regardless of problem complexity or domain. Higher-performing models produce more hypotheses/evidence, but do not exhibit more structured epistemic graphs.
Figure 6: Reasoning breakdowns dominate across all domain groups; breakdown rates exceed productive-motif rates everywhere.
Figure 7: Motif mean prevalence detailed for each environment; reasoning breakdowns are more prevalent than productive motifs across all environments.
Trace Intervention Experiments and Reliability
The authors probe whether providing partial successful traces as context rescues reasoning deficiencies—effectively an extreme scaffolding intervention. In workflow-construction domains, injecting one or two successful steps suffices to improve performance. In hypothesis-driven/strategic domains, substantial gains only materialize when near-complete trajectories are provided; early-stage interventions exhibit minimal effect. Reliability metrics () decay rapidly: in hypothesis-driven domains, the probability that all independent trials succeed drops below 0.05 at , even when success-trace interventions are applied. Failures recur across repeated trials, unaffected by scaffold architecture.
Figure 8: Scaffold interventions rescue workflow execution but not hypothesis-driven reasoning; the latter shows sharp unreliability unless nearly full traces are injected.
Figure 9: Recovery curves under success and failed trace interventions; hypothesis-driven environments exhibit minimal benefit from early injections.
Model Confidence and Context Sensitivity
Token-level log-probability analyses for open-weight models correlate low confidence with unrecoverability under partial interventions in hypothesis-driven and strategic-reasoning environments. Workflow domains (well-defined solution paths) show higher model confidence and monotonic, gradual intervention benefit; the epistemic gradient aligns with both behavioral motifs and performance decay.
Figure 10: Hypothesis-driven environments yield consistently lower mean log probability than workflow-based environments.
Practical and Theoretical Implications
- Outcome-only benchmarks mask epistemic defects; correct answers obtained via non-scientific reasoning cannot be assumed to generalize or be reliable in novel contexts.
- Scaffold engineering alone cannot repair reasoning deficits; improvements must target the base model and its training regimen.
- Until reasoning itself becomes an explicit training target, scientific knowledge produced by such agents lacks epistemic justification.
- Direct reasoning-process assessment is required to ensure AI-produced scientific results adhere to norms of self-correction and rational justification.
- The inability to adapt reasoning strategies to epistemic demand sharply limits the utility of current LLM agents in hypothesis-driven science.
Future Outlook
- Progress depends on incorporating epistemic criteria into model pretraining, potentially leveraging frameworks such as Corral for upstream training signal generation.
- Shared environments, tools, scoring functions, and annotation pipelines facilitate reproducible agent evaluation and may serve as substrates for training reasoning-anchored models.
- As AI scientist systems proliferate in chemistry/materials domains (Figure 11), the necessity for epistemically disciplined autonomous agents will intensify.
Figure 11: Sharp rise of AI-scientist publications within chemistry and materials AI literature; the share of AI-scientist papers is steeply increasing.
Conclusion
This work establishes that current LLM-based scientific agents execute workflows but do not reason scientifically. The epistemic process underlying their outputs is frequently undisciplined and invariant to task demand or scope, with outcome-based evaluation insufficient to detect these limitations. Reliable AI scientists will require base model improvements targeting reasoning itself, not task completion alone. Until these advances are realized, the scientific knowledge produced through such agents cannot be epistemically warranted.

What is this paper about?
This paper asks a simple but important question: Can today’s AI “scientists” really think like scientists, or do they just produce answers that look right?
The authors test LLM–based agents that are meant to run parts of scientific research on their own. They show that while these AIs can follow instructions well (like running a recipe), they often don’t reason like real scientists (like detectives who form ideas, test them, and change their minds based on evidence).
What questions did the researchers ask?
They focused on two big questions:
- Do AI agents follow the key habits of scientific thinking—like testing ideas, using evidence, and updating beliefs when data disagree?
- What matters more for success: the AI’s “brain” (the base model) or the “wrapper” around it (the scaffold) that organizes prompts, tools, and steps?
How did they study it?
The team ran over 25,000 experiments across eight science areas (like running lab analyses, planning chemical syntheses, identifying molecules from spectra, simulating materials, and solving circuits). They examined AI agents in two complementary ways:
1) Performance: what got done
They measured how well agents completed tasks of different types:
- “Recipe-like” tasks (workflow execution): The path to the answer is clear; the agent must do the steps correctly (e.g., run a simulation, train a model).
- “Strategy” tasks: The agent must plan carefully in a big search space (e.g., planning a multi-step synthesis).
- “Detective” tasks (hypothesis-driven): The agent must guess hidden facts, design tests, gather evidence, and change its mind if needed (e.g., figuring out an unknown molecule from lab data).
They tested three strong base models and two scaffolds (ways of organizing the agent’s steps, such as ReAct and structured tool-calling) to see which parts mattered most.
Think of:
- Base model = the AI’s “brain.”
- Scaffold = the “coach” or “planner” that gives the brain tools, formats, and a loop for acting and observing.
2) Behavior: how the AI reasoned
They looked inside the agents’ reasoning traces (the step-by-step thoughts and actions) and tagged each step as:
- H: Hypothesis (a guess)
- E: Evidence (data gathered)
- T: Test (an action that could confirm/refute a guess)
- J: Judgment (does the evidence support the guess?)
- U: Update (change the belief)
- C: Commitment (final choice)
They then checked for good patterns (like “guess → test → update”) and bad ones (like ignoring evidence or never testing a claim).
Extra tools and checks
- Knowledge vs. reasoning “quizzes”: They built question sets to separately test factual knowledge and reasoning skills. Using a method called item response theory (think: a smart way to score quizzes that adjusts for question difficulty), they estimated each model’s knowledge and reasoning ability.
- Trace “hints” experiments: They tried giving agents partial “solution steps” from past runs to see if that would help—like giving a student hints from a previous correct solution.
What did they find, and why is it important?
Here are the main takeaways:
- The AI’s “brain” matters far more than the “wrapper.”
- The base model explained most of the differences in how well agents did and how they behaved.
- Numbers: reasoning ability explained about 41% of the success, while the scaffold explained about 1.5%.
- Great at following recipes, weak at being detectives.
- Agents did well on clear, step-by-step tasks (like running simulations or training ML models).
- Performance dropped as tasks required more scientific thinking (forming and testing hypotheses, revising beliefs).
- The agents often ignored evidence and didn’t update beliefs.
- Evidence was ignored in 68% of reasoning traces.
- Only 26% showed “I changed my mind because the data refuted my idea.”
- Using multiple independent tests to confirm a conclusion was rare (7%).
- Same “thinking style” no matter the task.
- Whether the task needed careful testing or just execution, agents tended to use the same patterns.
- Stronger models produced more steps and fetched more facts, but they didn’t show more scientific “epistemic” discipline (like testing and revising).
- Giving partial hints helped only for recipe-like tasks.
- In workflow tasks, a few helpful steps boosted success.
- In detective-style tasks, agents needed almost the entire successful path to improve—small hints didn’t fix their reasoning.
- Repeating attempts didn’t make them reliable in detective-style tasks.
- Even trying several times, consistent success stayed low for the hardest, most scientific problems.
Why this matters: In science, how you reach a result is as important as the result. If an AI lands on a correct answer but got there by ignoring evidence or skipping tests, we can’t trust it to generalize to new problems—or to alert us when it’s wrong.
What does this mean going forward?
- Don’t judge AI “scientists” only by whether they get the right answer; judge how they think. We need evaluations that check for real scientific habits: forming testable ideas, using evidence correctly, and updating beliefs when data disagree.
- “Scaffold engineering” (just changing prompts, tool wrappers, or workflows) won’t fix the core issue. The reasoning style seems to come from the base model itself.
- Training should target reasoning, not just predicting the next word. Models need incentives and feedback that reward proper scientific thinking patterns.
- Be cautious when using AI agents to produce new scientific knowledge. Until their reasoning becomes more scientific, their results may not be trustworthy by scientific standards.
- The authors provide a shared evaluation framework and environments so the community can measure and improve AI reasoning over time.
In short: Today’s AI agents can run the steps of science, but they often don’t think like scientists. To make AI a trustworthy partner in discovery, we must teach and test it on the process of good scientific reasoning—not just the outcomes.
Knowledge Gaps
Unresolved gaps, limitations, and open questions
Below is a concise list of what remains missing, uncertain, or unexplored in the study, framed to guide concrete follow-up work.
- Limited model diversity: Only three base models (two closed-source, one open-source) were evaluated; conclusions about “base model dominance” need testing across broader families (e.g., smaller/older models, multilingual models, non-LLM planners, vision-LLMs).
- Narrow scaffold coverage: Only ReAct and structured tool-calling were tested; more expressive scaffolds (e.g., belief-state tracking, planning graphs, self-verification, debate/adversarial critique, multi-agent protocols, memory/working-memory modules) were not assessed.
- Temperature and sampling strategies: All runs used temperature 0.0, leaving untested whether stochastic exploration, best-of-n, self-consistency, or diverse decoding improves hypothesis testing, belief revision, or reliability.
- Iteration/compute budget constraints: Fixed iteration limits were imposed, but the sensitivity of epistemic behavior to larger budgets (more cycles, tool calls, or longer contexts) was not explored.
- Generalization beyond eight domains: Tasks are concentrated in chemistry, materials, circuits, and a single instrument (AFM). External validity to other scientific fields (e.g., biology, ecology, medicine, fluid dynamics, astronomy) remains untested.
- Real-world lab variability: Most environments are simulated or procedurally controlled; the impact of noisy, incomplete, or contradictory real-world measurements (sensor noise, failed experiments, instrument drift) on epistemic behavior is unknown.
- Multimodality limits: While instruments and spectra are available via tools, the study does not assess agents’ reasoning when directly interpreting raw multimodal inputs (e.g., images, spectra plots, microscopy videos) with vision-LLMs.
- Human baseline comparison: No side-by-side evaluation against human students/experts performing the same tasks; the magnitude and nature of the gap between agents and humans (including error patterns) remains unknown.
- Diagnostic QA validity: The IRT-based separation of “knowledge” vs “reasoning” depends on researcher-authored items; item independence, construct validity, and susceptibility to training-data leakage were not validated against external psychometrics.
- LLM-based epistemic annotation reliability: Large-scale epistemology labels were produced with an LLM (Claude Sonnet 4.5). Robustness of these labels (e.g., inter-method agreement with humans, sensitivity to prompt phrasing, cross-model bias) is not reported.
- Scope of manual validation: Only 773 traces were manually annotated by two experts; inter-annotator agreement metrics, sampling strategy, and representativeness of those traces are not detailed.
- Metric construct adequacy: The epistemic-graph taxonomy emphasizes operations like H/E/T/J/U/C; whether this schema fully captures legitimate scientific strategies (e.g., Bayesian updating, exploratory heuristics, abductive loops with pragmatics) is unexamined.
- Process vs outcome metric alignment: The link between proposed process metrics (evidence uptake, refutation-driven updates, convergent evidence) and downstream scientific utility (novelty, replicability, predictive value) remains to be empirically established.
- Causality of evidence non-uptake: It is unclear whether non-uptake stems from model limitations, token budget/context overflow, tool interface frictions, docstring design, or prompt framing; targeted ablations are needed.
- Tool verbosity effects: Main results focus on brief docstrings; the impact of more comprehensive tool documentation on epistemic patterns is deferred to the appendix and not analyzed in depth.
- Tool reliability and ambiguity: Tools return deterministic, clean signals; how agents handle ambiguous, low-SNR, or conflicting tool outputs is not tested.
- Token-level confidence generality: Log-probability analyses rely on a single open-source model; whether token-level confidence predicts intervention recoverability across closed-source models remains an open question.
- Reliability under adaptive memory: The “probability all k trials succeed” was measured with independent trials; whether memory across trials (meta-learning/retrospective reflection) improves reliability is unknown.
- Best-of-n vs all-k reliability: The study highlights decay of P(all k succeed); analysis of P(at least one succeeds), expected best-of-n performance, and optimal sampling/selection strategies is missing.
- Effectiveness of social scaffolds: Peer-review-like multi-agent setups (critic–proposer, debate, argumentation frameworks) were not tested; whether social mechanisms induce refutation and belief revision remains open.
- Training interventions: The work argues for training on reasoning processes but does not test specific methods (e.g., process supervision, RL from epistemic feedback, counterfactual data augmentation, refutation traces, multi-evidence curricula).
- Data for epistemic training: Practical pathways for sourcing/curating process-level supervision (labeled epistemic graphs, falsification examples, multi-test convergence) and their annotation cost/quality are unspecified.
- Dynamic task difficulty and curricula: How reasoning behavior evolves under systematically staged curricula (increasing ambiguity, conflicting evidence, cost constraints) was not explored.
- Memory and belief-state modeling: Agents were not required to maintain explicit, queryable belief states; whether structured internal state (e.g., probabilistic hypotheses, test–evidence links) improves evidence uptake and belief updating is untested.
- Interpretability of failures: No mechanistic interpretability or probing of model internals was performed to identify why evidence is ignored or hypotheses remain untested.
- Context-length and long-horizon effects: The impact of very large contexts (longer histories, richer lab notebooks) on maintaining and revising beliefs was not assessed.
- Interface design sensitivity: Variations in tool APIs, error messaging, and affordances (e.g., explicit cost signals, uncertainty flags) were not ablated for their influence on epistemic behavior.
- Continual learning and adaptation: The study does not examine whether agents improve epistemic behavior over repeated exposures or with environment-specific fine-tuning.
- Governance and misuse: If agents produce results without epistemic justification, how institutions should evaluate, audit, or constrain AI-generated scientific claims remains unresolved.
- Multilingual and cross-cultural science: All evaluations appear in English; whether epistemic patterns change in other languages or cultural scientific practices is unknown.
- Reproducibility constraints: Use of closed-source frontier models limits exact replication; a standardized open set of strong baselines and trace datasets for process-level benchmarking is needed.
- External benchmark alignment: How the proposed epistemic metrics correlate with success on existing agent/science benchmarks (e.g., re-implementation under peer review, open-ended discovery) was not quantified.
- Scaling laws for epistemic behavior: The dependence of evidence uptake, refutation rate, and convergence motifs on model size, training data composition, or instruction/process-supervision intensity is not mapped.
- Cross-domain transfer: Whether improvements in epistemic behavior in one domain transfer to others (e.g., from circuits to spectroscopy) is untested.
- Robustness to prompt variations: Sensitivity of epistemic behavior to small changes in task prompts, instructions about scientific norms, or meta-prompts enforcing falsification was not systematically measured.
- Heteroscedastic cost–information tradeoffs: While some tasks include costful tests (e.g., HSQC), agents’ ability to plan under heterogeneous costs/uncertainties and to compute value of information remains unquantified.
- Comparison to symbolic/explicit pipelines: Baselines like expert systems (e.g., DENDRAL-like rule engines) or programmatic planners were not included for direct process-level comparison.
- Negative evidence handling: Beyond “non-uptake,” detailed characterization of how agents treat negative or contradictory results (e.g., weighting, dismissal, re-testing) is missing.
- Failure taxonomy granularity: Epistemic “anti-patterns” were tallied, but fine-grained causal chains (e.g., misinterpretation → wrong test → failure to update) and their relative frequencies were not distilled to guide targeted fixes.
- Tool-choice optimization: Exploration vs exploitation and test selection policies (e.g., adaptive experiment design/value-of-information heuristics) were not benchmarked against agent strategies.
- Open-ended science tasks: The environments are goal-directed with clear scoring; whether agents can sustain epistemically disciplined open-ended exploration (e.g., hypothesis generation without a known ground truth) remains an open frontier.

Notes on feasibility and dependencies
- The paper’s key dependency is access to and integration with the Corral framework, standardized tools, and domain backends; some instruments (e.g., AFM) and simulators (LAMMPS) may be costly or require expertise.
- Many immediate applications rely on APIs that expose token-level log probabilities and structured tool call interfaces (not universally available).
- Long-term advances depend on community-wide standards, shared datasets of annotated traces, and willingness of model providers to optimize for epistemic criteria rather than only task accuracy.
Glossary
Agent scaffold: A framework that wraps a base model in a loop, governing prompts, tool routing, memory management, and logic by appending observations to the conversation history. Example in paper: "Common implementations include ReAct and structured tool-calling interfaces."
Dialectical reasoning: A reasoning style involving generating, testing, and refuting hypotheses in a process of disciplined inquiry. Example in paper: "Retrosynthetic planning requires multi-step planning under constraints, and hypothesis-driven inquiry requires generating, testing, and revising competing hypotheses."
Epistemic norms: Standards that dictate the reasoning processes adherent to scientific inquiry, ensuring self-correction and reliability. Example in paper: "Yet whether their reasoning adheres to the epistemic norms that make scientific inquiry self-correcting is poorly understood."
LDP (language decision process): A framework for representing observations and actions in text as part of a decision-making process, commonly used with LLMs. Example in paper: "We adopt the language decision process (LDP) framework, a partially observable Markov decision process in which observations and actions are represented in text."
LLM-based scientific agents: AI systems utilizing LLMs to autonomously conduct scientific research, including hypothesis generation and experimentation. Example in paper: "A growing number of LLM-based agents are now designed to conduct scientific research autonomously."
Reasoning breakdown: Occurs when an agent's reasoning process fails to adhere to disciplinary scientific inquiry, such as ignoring evidence or failing to update beliefs. Example in paper: "Reasoning breakdowns dominate across all domain groups, with evidence non-uptake occurring in 68% of traces."
Scaffold engineering: The process of developing and optimizing the structural framework that wraps around LLMs to improve task execution. Example in paper: "Much current engineering effort focuses on scaffolding, but the reasoning patterns persist across scaffold conditions."
Systematic performance evaluation: A methodical assessment of an agent's performance that decomposes the contributions of the model and scaffold elements. Example in paper: "The first is a systematic performance evaluation across controlled environments...to separate the contributions of the base model from the agent scaffold."
