Abstract

fetched live from OpenAlex

The academic reward system encourages scholars to selectively collect and analyze data in a search for statistically significant (p < .05) findings to accumulate articles in prestigious journals. Evidence suggests that such “p-hacking” is endemic throughout science, and work has begun to reveal the extent of this phenomenon in management journals as well. We advance this work by examining p-hacking in two prestigious management journals: AMJ and ASQ. We show that empirical distributions of statistical significance in these journals exhibit too many just-significant (.04 < p < .05) and too few just-below-just-significant (.03 < p < .04) hypothesis tests, and provide arguments and evidence regarding which particular articles are most likely to reflect this behavior.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
