Most CRO advice assumes customers weigh features and price like a spreadsheet. They don't. Real conversion wins come from psychology, not checklists. In this piece, we walk through eight principles: anchoring, the goal gradient effect, loss aversion, reciprocity, social proof, authority bias, the default effect, and Hick's Law, each tied to a real company: Amazon, Costco, Trader Joe's, Stripe, and more. Everyone comes with the mechanism behind it and a fix you can actually use.
