Many think that cognitive skills are crucial to achieving your goals. Such an approach is called “cognitive hypothesis.” Middle-class parents used to be the most concerned about their children having a high IQ and were therefore the most devoted proponents of the “cognitive hypothesis.” They would pay attention to reading, patterns, and calculating. The reason was that they feared the lack of cognitive stimulation in their low-income family would make their offspring fail in life.

This global anxiety created the “Rug Rat Race,” which galvanized parents to make their two-year-olds enroll in tutoring centers. During that period, Hart and Ridley conducted a study titled “Thirty Million Word Gap,” which emphasized the influence of the number of words children hear at home on their life paths and success. Undoubtedly, those from well-off households tend to hear more words per day, which puts those from underprivileged backgrounds at a disadvantage.

In fact, over time, the “cognitive hypothesis” was refuted. Leading psychologists, economists, and neuroscientists started to reshape previous simplistic views. From that point onward, “noncognitive” skills have been considered the most important. Unlike mechanical skills that can be developed through simple drills, character strengths are built in a mysterious way. Among them are optimism, discipline, an open mind, conscientiousness, and determination.

This new school of thought was also advanced by Nobel Prize-winning economist James Heckman, who studies the paradox of high-school graduates. The strange thing was that high-school graduates who earned a GED and high IQ scores weren’t more successful in life than dropouts without any credentials. And the answer is rooted in noncognitive skills. It turned out that those who earned a GED were intelligent but lacked persistence, a game-changer in college and the workplace.

“Tools of the Mind” is a training for children that again demonstrates the lack of logic in “cognitive hypotheses.” The curriculum for this training focuses on self-regulation rather than on math or reading. Concentration on early academics is not going to give the same results as controlling emotions or staying focused. Within the “Tools of Mind” program, children are taught to follow rules and use self-talk to tackle tasks and organize their day.
