The Ultimate Intelligence Test
The “test”, which really seems more like a sophisticated data collection tool for someone doing research in psychology or cognitive science, consists of twelve ‘games’ that test various brain functions, like memory, planning, categorizing, and the like. They are mostly fun, but be warned: it can be a fairly taxing process.
It takes around 30 minutes to complete all the tests, and when you are finished (and complete a short survey), your results, and your relative rankings among all test-takers, are displayed for every activity. In addition, the authors explain what they think each exercise is really testing.
It’s definitely a fun way to waste half-an-hour. Just make sure you are well-rested!
