The same could be said for behaviorism and microeconomics. Seeing how people react in what is essentially a laboratory environment is common in microeconomic experiments using random samples and controlled environments.
Often, not at all. Especially psychiatry.
I get the impression some people here aren’t going to outright deny global warming, but don’t think rising sea levels and widespread desertification are much of a big deal. The fact is, within the climate science field there’s practically a consensus that it’s occurring and anthropogenic carbon emissions are responsible. Rejecting climate models because of the fact that they use empirical methods- I can see why you’d say that. But it’s ignoring that induction is necessary just to get by in everyday life and interact with people.
