TL:DR … When you actually think more, feelings don’t screw you up as much.

I had a prof in grad school who talked about an ‘enthusiasm index’ in academic research which essentially described how excited (emotional) people got about the findings of research (rational). In the real world, that’s just not how it’s supposed to work. Research is painstakingly logical, rational, thoughtful, step-by-step. Emotion has no place.

The Enthusiasm Index in academic research essentially stated the more emotional the response to a study, the higher the probability the quality of the research was low (poorly designed, small or non-random samples, tiny p-ratios, maybe even cheated, etc.). Elizabeth Holmes at Theranos was probably a proud although unwitting purveyor of her own Enthusiasm Index and blinded many investors with the emotional high of a get-rich-quick pitch. Warren Buffett THINKS through his investments; feelings really are best served elsewhere…
