I know untimed tests exist, but they're still under the constraint of testing people that have lives to get to. People have jobs, loved ones, classes to go to, lives to live, and as such even untimed tests aren't really untimed, since you'd have to be really vain to spend 16 hours on an "untimed test with no rewards" just to get a better score. So the question is, as a mind experiment, if you take the ceiling item of a Raven's test and take an average Joe, then lock them in a room with a bed and nutrition for a week, and say if they don't solve it, they're gonna die akin to a Saw scenario, will they solve it or will they face their doom?
