By testing. The only way to find out if a test is performing well is to look at the results. I wouldn’t know how to test for these things as I am neuro divergent and don’t value physical processions almost at all. I’m pretty much un-bribable, so I could never develop a test for if someone is susceptible to it. I know there was a study that found normal people feel great pride winning a game of monopoly, even when they know the game is rigged in their favor. I can’t imagine that being fun as a base line of who I am. Are there enough people out there who are immune to temptation in the way I am? No idea. But maybe we could work on some tests to find out.
