Anecdotal counterpoint: I too skipped three grades (early ones) and ended up in college at 15 (and then on to grad school at 19); and based on how I reacted to boredom even then I am deeply certain that if I hadn't been accelerated, and just given "enrichment" or whatever, I would have checked out and washed out. Meanwhile, I certainly had a different social trajectory than your typical teen-20s-30s person, but that was probably a foregone conclusion. But, anecdotes. > I wonder if they lack good ways of measuring this. The rest of your post implies that you wonder that because you had a bad social experience; but the study is not claiming that people who are accelerated have good outcomes. It's saying that acceleration-or-not doesn't covary with psychological outcomes (which is basically what's going on in your "grass-is-greener" comment)—your life could suck, or not, but either way it's not because you did or didn't get accelerated.
