This could be inspected in two directions: - Does grit predict success? (forwards) - Do successful people project grit? (backwards) Although it's always somewhat context-sensitive, with both figures you could learn how much signal to derive from the latter. If we learned that grit wasn't necessarily an indicator of success, then it'd arguably be a bit callous of successful people to project grit, given that plenty of other people go through hard times without being able to achieve similar outcomes.
