Grant notes his colleague's criticism of him as a "professional debunker" as though it's a bad thing for our nation's psychology professors to set out to debunk research. But that's really just the scientific method. Scientific claims are not presumed to be true -- instead, we only treat them as true if rigorous, neutral methods demonstrate that the claim provides a better explanation of a phenomenon than the dreaded null hypothesis. Professional debunkers are very important, particularly in a discipline where much research has been shown to be wrong. KEEP DEBUNKING, JESSE!

One of the problems I have with Primeworld is that it seems to imply an incoherent model of the world where there are lots of factors that each have large effects. It seems fundamentally impossible for e.g. 50 different factors to *each* explain 70% of some outcome.

Consider walking speed. Priming research tells us that observing or thinking about old people has an effect. I assume things like being late, being pursued, being in pain, being "in the moment" and taking in the world around you, etc., are also important determinants of walking speed. Given this, Primeworld seems to need to assert that one of two things must be true: either (a) we happened to discover that observing old people belongs to small number of potent stimuli which strongly affect walking speed, or (b) walking speed is an incredibly fragile property, and hundreds of small things have to be *just right* all the time in order for a person to sustain a fast or even normal walking pace. Both possibilities seem very unlikely to me.
