Here’s where emotions come in handy. Every feeling is like a summary of data, a quick encapsulation of all the information processing that we don’t have access to. (As Pham puts it, emotions are like a “privileged window” into the subterranean mind.) When it comes to making predictions about complex events, this extra information is often essential. It represents the difference between an informed guess and random chance.
I remember using my gut to solve a lot of support cases back in the day. Too much information to try and rationally sort through, yet I somehow could tell you what was going on… 🙂
