Not really no? I mean, If it was, researchers would've scrambled to try and determine its usages and feasibilities in terms of anything and everything really. I reckon you can use it to determine their personality albeit a bit forced, but there's no exact 100% answer to that and there would always be edge cases on it. As for level of intelligence, heck you can survive here even if you closed your eyes and pray every time you play, highly doubt they can filter those instances out. If they don't, then the entire context of being able to quantify an individuals intelligence or even categorize it vanishes really.
