Causal complexity demands community coordination

open access: yesBehavioral and Brain Sciences, 2021
Yarkoni’s argument risks skepticism about the very possibility of social science: If social phenomena are too causally complex, normal scientific methods could not possibly untangle them. We argue that the problem of causal complexity is best approached at the level of scientific communities and institutions, not the modeling practices of individual ...
