“Lowering P-value thresholds may also exacerbate the “file-drawer problem”, in which studies with negative results are left unpublished, says Tom Johnstone, a cognitive neuroscientist at the University of Reading, UK. But Benjamin says all research should be published, regardless of P value.


Other scientific fields have already cracked down on P values — and in 2015, one psychology journal banned them. Particle physicists, who collect reams of data from atom-smashing experiments, have long demanded a P value below 0.0000003 (or 3 × 10−7) because of concerns that a lower threshold could lead to mistaken claims, notes Valen Johnson, a statistician at Texas A&M University in College Station and a co-lead author of the paper. More than a decade ago, geneticists took similar steps to establish a threshold of 5 × 10−8 for
genome-wide association studies, which look for differences between people with a disease and those without across hundreds of thousands of DNA-letter variants.”

““We don’t believe that the data we are collecting is any kind of realistic peer review, but it does tell us something about the types of papers people find interesting and what leads them to be
suspicious,” Leek says. “Ultimately we hope to correlate this data with information about where the papers are published, retractions, and other more in-depth measurements of paper quality and interest.”

But don’t take Papr too seriously, because its developers don’t. “This app is provided solely for entertainment of the scientific community and may be taken down at any time with no notice because Jeff gets tired of it,” the Papr website says.”
