The third level of tests was uniformly harder; none of the kids did well. However, the two groups of kids—the praised-for-effort group and the praised-for-intelligence group—responded very differently to the situation. “[The effort group] dug in and grew very involved with the test, trying solutions, testing strategies,” Dweck said. “They later said they liked it. But the group praised for its intelligence hated the harder test. They took it as proof they weren't smart.”
