Disgust is the most underrated force in business decision-making. Not metaphorical disgust — the visceral, gut-level reaction that makes you push your chair back from the table. The psychologist Paul Rozin spent decades mapping this emotion and found something strange: disgust operates as a contagion logic, not a cost-benefit one. A single contaminating element — a dishonest partner, a product that 'feels wrong,' a culture that tolerates one ugly behavior — spreads through our assessment of everything it touches, regardless of the actual numbers. This is why Arthur Schopenhauer, in his analysis of motivation, distinguished between rational willing and what he called 'will as body' — the pre-cognitive drives that determine action before reasoning even begins. What Rozin and Schopenhauer together reveal is that in high-stakes human decisions, the disgust system often votes first and the spreadsheet rationalizes second. The practical consequence: when you feel that inexplicable resistance to a deal, a hire, or a direction — the kind you keep overriding because the logic is sound — that resistance may be pattern recognition your conscious mind hasn't caught up with yet. Don't override it cheaply. Make it explain itself.

What is the last decision you made that felt logically correct but left you with a residue of unease — and what specifically were you overriding to make it?
