How to read this

A note on evidence.

Marketing psychology is a field with a replication problem. Some of its most quoted findings — ego depletion, certain priming effects, the stronger claims about power posing — have not held up. I try not to build arguments on them.

Where I cite research, it is usually work with large samples, commercial data, or a long record of practical replication. Where I am reasoning from experience rather than evidence, I try to say so. You should treat these essays the way you should treat any marketing advice: as a set of hypotheses to test against your own market, not as laws of nature.
