PPPR is not only the abbreviation of “pandemic preparedness prevention research” but also of “post publication peer review”. PPPR is particular important in a scenario described in an excellent commentary of an excellent article that highlights the strategy
for a “team of rivals” in which you “invite your academic rivals to work with you.” It still depends too much on the goodwill and honesty of people with too much to lose. Also, Kahneman, who is quoted/paraphrased, seems to be missing the point when he says that “With competing hypotheses and theories in play, the rivals will quickly spot flaws such as hypothesis myopia, asymmetric attention or just so storytelling, and cancel them out with similar slants favouring the other side.”
No, they wont’t, they would have to leave the club. Without independent PPPR any bias cannot be discovered as can be seen in the classical examples of synchronized groups in GWAS or farming studies – crushing opponents by hugging.
