"We validated it," Angela says. "We showed it predicted objective measures like graduating West Point's first summer [cadet basic training] and winning the National Spelling Bee. And then in all the studies we measured IQ and consistently found that IQ really is something else." Being a hardworking or self-controlled kid is not the same as being a smart kid. Angela and her team had parents rate their kids, had teachers rate their kids, and had kids take two different questionnaires and a delayed-gratification test ("Do you want a dollar today or two dollars in a week?"). They had them do a hypothetical delayed-gratification test with a large number of choices (two dollars today, seven in three months).
"When you average across all of those things, we found you can predict things like their grade point average startlingly well—much better, in fact, than IQ does—as well as changes in grades," Angela says, a finding described by like-minded Stanford colleague Carol Dweck, whom Angela thinks of as a role model, as "a landmark piece of work."
