Cues in the 50 tasks and how generated hypotheses match the articles

Analysis date: 27 October 2026. Corpus: the initial 2997 hypotheses from four generators across three modes. The repeat generation run of Claude Opus with a separate isolation check is excluded from this analysis.

What was tested

We tested the association between the content of the research question and the share of matches with the reference finding among the generated hypotheses. Under the primary matching criterion, at least two of the three judges from other companies gave the hypothesis a score of 3 or higher. Under the strict criterion, at least two judges gave a score of 4 or 5. These scores measure how well a hypothesis matches the article; alternative hypotheses with low scores may still prove true in other experiments.

This analysis evaluates the generation benchmark. Predictor forecasts and selection results were omitted from the calculations. A separate forecasting benchmark can validly use hypotheses of any origin, including manually written hypotheses and hypotheses generated with cues. Their origin defines the composition of the evaluated set; by itself, it does not invalidate the assessment of forecasting.

Question annotation

A question score of 0 means that the question states only the phenomenon to be explained. A question score of 1 means that it specifies a class of explanations, a source of perturbation, or a general process. A question score of 2 means that it already gives a substantial part of the causal link, a specific intervention with the direction of its effect, key molecular players, or a sufficiently narrow combination of conditions. The question score measures how strongly the search space is constrained. It does not establish a protocol violation: some details could represent valid background knowledge.

GPT-6 Astra with a high reasoning level annotated the tasks using the full questions, the background, and the reference findings. For borderline cases, adjacent plausible question scores were recorded in advance. The annotations and the analysis plan were saved in commit 82123e40 before being linked to the individual generation results in this analysis. Summary results and two previously discussed examples, AMPK and motor neuron death, were known before the annotation. A separate calculation was performed without those two tasks.

An alternative adjacent question score was recorded for 35 of the 50 questions. The robustness check replaces all of those question scores simultaneously. This check tests how sensitive the conclusion is to category boundaries; it does not measure agreement among independent experts.

Primary comparison for single-request generation

In each of the 50 tasks, four generators proposed five hypotheses each, yielding 1000 hypotheses in total. For each task, the four shares of matches among the generated hypotheses were averaged; the task is the unit of statistical analysis. Thus, the 1000 hypotheses were not treated as independent observations.

In the table, the confidence intervals (CIs) for the shares of matches are given in percent. Because every task has the same number of hypotheses in this mode, the share of matches among all hypotheses equals the mean across tasks.

Under the primary criterion, the difference between group 2 and groups 0 and 1 combined was 13.5 percentage points, 95% CI [2.1, 25.0]. In groups 0 and 1 combined, 94 of the 760 hypotheses (12.4%) matched the article. Under the strict criterion, the difference was 3.3 percentage points, 95% CI [-0.5; 7.4]. This is a pre-planned descriptive comparison, and its confidence interval is not adjusted for multiple comparisons.

The most explicit cues are associated with a higher share of matches among the generated hypotheses in this breakdown. However, there is no monotonic increase from group 0 to group 2: group 1 had a lower share of matches among its hypotheses than group 0. Consequently, the positive difference between group 2 and groups 0/1 is consistent with a weak overall rank correlation. These data do not support the claim “the stronger the cue, the better the generation” with sufficient certainty.

Other generation modes

These comparisons are exploratory and use the same tasks. In the multistep pipeline, there is a noticeable positive association under the strict criterion, but it does not replicate in Omega Point. The reported P values are unadjusted across all exploratory checks. In the analysis of individual models and modes, no comparison reached P < 0.05 after correction for multiple comparisons (Holm) across the 24 tests. For two combinations, there were no matches under the strict criterion at all, leaving the correlation undefined; in calculating the correction, they were assigned P = 1.

Robustness of the primary result

For the partial rank correlation, only the confidence interval was calculated; P was not calculated for that row. Length was measured in Unicode characters; the length of the reference finding includes the statement and its key elements.

When each individual task was left out in turn, the primary correlation remained within [0.12, 0.22]. Its sign therefore does not depend on any single task. Under the pre-recorded alternative annotation of borderline questions, however, the correlation is close to zero and reverses sign. This shift reflects substantial classification uncertainty rather than confirmation of no effect.

Scoring the question together with the background yields a stronger association. In this supplementary check, the permutation P is below 0.05, whereas the 95% confidence interval from resampling across tasks includes zero. The two methods quantify uncertainty differently, especially when individual categories contain few tasks and many values are tied. This exploratory result requires independent annotation and confirmation.

Limits of inference and the next experiment

The current data support a positive association for the group with the most explicit cues under the primary matching criterion. The overall correlation is weak, and the result is sensitive to how the category boundaries are drawn. The causal claim “these phrasings helped” remains untested: different tasks vary in difficulty, in how well the mechanism is known, in the specificity of the reference finding, and in how the judges respond. Comparing different tasks does not show what will happen if a cue is removed from the same task.

Testing the causal effect requires preparing two input versions for each task: the current version and a version in which cues to the reference finding are removed while sufficient background is retained. The same models should then independently generate an equal number of hypotheses under identical limits across several replicates, with a randomised run order. Judges should score the hypotheses blinded to the input version, and the primary comparison should be paired by task. A control generator that produces affirmative restatements of the question will additionally show what share of matches among the generated hypotheses can be achieved without adding substantive content to the question. These are tests of generation.

For the forecasting benchmark, the resulting set of hypotheses is evaluated separately. Forecasting performance can also be compared across different hypothesis sources if needed, though that represents a distinct research question.

Computation and reproducibility

The analysis used 99,999 permutations of question scores across whole tasks and 10,000 resamples of whole tasks with replacement. Two-sided P values were calculated from the absolute value of the correlation by adding one to both the numerator and the denominator. Confidence intervals represent the 2.5th and 97.5th percentiles, with ranks and ties recalculated within each resample. The global random seed is 20261027. The small sample size motivates using a permutation test rather than an asymptotic P value; see the Spearman documentation and the permutation test documentation.

In modes with varying numbers of retained hypotheses, the shares of matches among generated hypotheses were first calculated within each task, model, and mode, and then averaged with equal weight across cells. All 2997 binary outcomes were independently reconstructed from the raw judge scores after excluding the generator’s own company. We verified the numerators, denominators, task identifiers, tie-handling of ranks for equal shares, the exact permutation distribution on a small synthetic example, and the handling of constant variables. The primary Holm correction family comprises the two thresholds in single-request generation; a separate exploratory family comprises the 24 combinations of model, mode, and threshold. The supplementary robustness checks are not used as standalone confirmatory tests.
