p values are meant to relate whether or not 'some' hypothesis is statistically relevant versus a control study. For something like biology, human nature, dieting, weight loss, in a world where you can't really control how stressed someone is, how far they walk to work, among 100 other things... if you're trying to find out how 'the potato' works, safe citizen science (a Riff trial) may be far more effective than 'traditional' proofs to get to the bottom of something that works, and then someone can do a controlled study.
