Don't even have to read the paper to know exactly what transpired here with high confidence. The author(s) set up an experiment without a hypothesis, threw in 100 candidate variables such as 'were they exposed to blue light', 'was the roof on fire', etc etc. They calculated P-values on all 100 and with a threshold of P < 0.05, they predictably rejected the null hypothesis 5 times. Then they conveniently left out 90 or so variables that failed the test.

- gattis 6y agowow thank you, i don't know how i never knew the term for this. it's gotten frustrating explaining so often, as it happens too often. as my old econometrics professor would say, "knowing a little bit about statistics is a very bad thing"
