> "I believe emotion is useless" Some time ago, my wife suffered from an illness that nerfed her emotions. It was surprising just how much her ability to reason degraded. Reasoning depends heavily upon emotional responses like feeling uncomfortable, surprised, curious, or frustrated by the data / facts / information. One with reduced emotions becomes disinterested; they simply stop caring about understanding. They stop caring enough to work through difficult problems. They don't care enough to search for better data or better ideas. I would agree that it's unhealthy to be guided by emotion in the sense of "I feel this is true" or "I believe this because I want to". This sort of emotion is mostly a distraction from rationality. But it's entirely healthy to be guided by emotion in the sense of "I care about getting this right" or "I'm bothered by these details not fitting". Without that sort of emotion to push you into rationality, you end up settling for weak, halfhearted, and ultimately irrational explanations.
