On the other hand, the object of study for psych is intrinsically interesting since we are people and if something reliable can be gleaned then it's certainly worth money. My concern is that "bigger, better" (as you say) would have to include millions of people across cultures and times, tracking longitudinally, with randomization and controls. (Again, more complexity requires more statistics, not less.). Is this practical? Maybe ...
