New Publication by Asanov et al. traces reporting bias in a large representative sample of PhD dissertations and following publications

Doctoral dissertations provide evidence about research practices in early-stage research. We examine reporting bias by manually collecting over 94,000 test statistics from a random sample of German dissertations and their follow-up papers worldwide. The authors observe selective reporting, as only a fraction of the tests in the dissertations is reported in follow-up papers. Unexpectedly, no increase is found in reporting bias in follow-up papers compared to dissertations nor, generally, reporting bias in dissertations or papers. Self-selection into higher-impact journals based on statistical significance may reconcile our finding of selective yet "unbiased" reporting with prior evidence suggesting pervasive reporting bias.
