Experiments
Each one measures something different, and every one reports to the same nine dimensions.
Stroop Task
3 minName the ink colour, ignore the word. Trivial until the word fights back.
Prisoner's Dilemma
4 minTen rounds against an opponent who remembers. Betraying always pays more — and if you both think that, you both lose.
Ultimatum Game
3 minSplit a pot, then have one split with you. Theory says take any offer. You won't — and what you refuse is the point.
Monty Hall
4 minThree doors, one prize, one opened. Switching wins twice as often — and almost nobody does it.
Asch Conformity
4 minFive people answer before you, out loud, and sometimes they're unanimously, obviously wrong. Do you trust your eyes?
Trolley Problem
5 minTen dilemmas with no good answer. Same arithmetic, different hands — and almost nobody answers both the same way.
A different kind of measure
Self-Report Profile
~15 minA questionnaire, not a task — the public-domain IPIP-NEO-120, measuring the Big Five across thirty facets. It asks what you say you're like; the games above watch what you do. Exploratory, private by default, and not a clinical test.
