Gut Decisions
Gut decisions are choices made first by feeling, such as trust, unease or attraction, with the logical reasons we give afterwards often serving as explanations built to justify a verdict already reached.
In Start with Why, Simon Sinek grounds this in a picture of the brain. The outer layer, the neocortex, handles analysis and language and lines up with What in his Golden Circle. The older inner structures, which he groups as the limbic brain, carry feelings like trust and loyalty. They drive behaviour and decisions but cannot put anything into words, and they line up with Why and How. That is why "it just didn't feel right" is real data, not a dodge. This tidy layered brain is a simplification that neuroscience has moved past. Still, the core observation holds up in behavioural research: feeling usually moves first and reasoning follows. Two consequences follow. Leading with features and figures speaks to the part of people that understands but doesn't decide. Your own reasons also deserve some suspicion, because they may be working as a lawyer, not a judge. Gut isn't always wrong. It just shouldn't go unexamined.
A real-life example
Maya is weighing two job offers. She builds a spreadsheet of salary, commute and title, and Offer B wins on paper by 8%. Yet she keeps rerunning the numbers. Finally she admits she left the interview for Offer A feeling lighter, because the manager asked about her goals instead of reciting the job description. Once she names that feeling, she can test it. She calls a former employee, confirms the culture is real, and takes A knowing exactly why.
How to use it
- 1Before listing any reasons, write down your gut answer in one line. That makes the feeling visible instead of letting it hide inside your spreadsheet.
- 2Ask what the feeling is responding to: a person, a risk or a memory. Then check that one thing with a fact or a phone call.
- 3When persuading others, open with why it matters to them. Offer the figures as support, not as the opening argument.
