The emotion default is the tendency to make decisions that feel right rather than ones that are right. This is not a character flaw — it is biology. Our emotional systems respond faster than our reasoning systems. By the time we are consciously thinking about a situation, our emotional brain has already filed a verdict. The problem is not that we have emotions. The problem is when we mistake the emotional verdict for the reasoned one. Someone who offers criticism feels like an enemy — but might be your most useful advisor. An opportunity that makes you excited feels right — but excitement is not evidence of quality. The discipline of the emotion default is not suppressing feelings. It is learning to notice what your emotional system is telling you, then choosing whether to act on it or examine it.
