isn't emotion basically system1 in thinking fast and slow? optimized for making snap decisions yes but far from being an illegitimate source of information. there are a lot of examples where system1 gives you the wrong answer, but IIRC there are also plenty of examples where system1 is exactly right especially when there is time pressure. the book "Blink" is basically its antithesis offering examples where trusting system1 leads to better outcomes than overthinking it with system2.
