Bem, Tressoldi, Rabeyron and Duggan report a small overall effect across ninety experiments and argue that bias-correction methods do not remove it. Critics answer that the correction methods available cannot distinguish a genuine small effect from a literature filtered by what got written up, particularly where many of the constituent studies were not pre-registered. The dispute is about the adequacy of the statistical tools, and it is live in the wider methodology literature and not only in parapsychology.
What would resolve this A registered-report replication series of adequate power, with the analysis plan lodged in advance and a commitment to publish, run by laboratories on both sides.
