Just-identified IV is little biased unless endogeneity is egregious. And bias is halved by screening on sign(first-stage t-stat). Just in: M. Kolesar and I show that among pretests of the form t>c, setting c=0 minimizes bias, while c>0 can increase bias

Rainfall can be independent of potential outcomes and therefore the reduced form have a causal interpretation and yet not satisfy exclusion and thus the causal interpretation is very hard if not impossible to interpret. This is an example of how you need independence & exclusion
