Since the beginning of the twentieth century, psychologists have measured a relatively small range of abstract skills—factual recall, analogical reasoning, and vocabulary—in the belief that they reflect an innate general intelligence that underlies all kinds of learning, creativity, problem solving, and decision making.

Not only do general intelligence and academic education fail to protect us from various cognitive errors; smart people may be even more vulnerable to certain kinds of foolish thinking.

Intelligent and educated people are less likely to learn from their mistakes, for instance, or take advice from others. And when they do err, they are better able to build elaborate arguments to justify their reasoning, meaning that they become more and more dogmatic in their views. Worse still, they appear to have a bigger “bias blind spot,” meaning they are less able to recognize the holes in their logic.

Besides cognitive reflection, other important characteristics that can protect us from the intelligence trap include intellectual humility, actively open-minded thinking, curiosity, refined emotional awareness, and a growth mind-set. Together, they keep our minds on track and prevent our thinking from veering off a proverbial cliff.

“People may say things will change, but then things go back to the way they were before,” Sternberg said. Just like when he was a boy, teachers are still too quick to judge a child’s potential based on narrow, abstract tests—a fact he has witnessed in the education of his own children, one of whom is now a successful Silicon Valley entrepreneur. “I have five kids and all of them at one time or another have been diagnosed as potential losers,” he said, “and they’ve done fine.”

If we consider that SATs or IQ tests reflect a unitary, underlying mental energy—a “raw brainpower”—that governs all kinds of problem solving, this behavior doesn’t make much sense; people of high general intelligence should have picked up those skills. Sternberg’s theory allows us to disentangle those other components and then define and measure them with scientific rigor, showing that they are largely independent abilities.

There is also framing: the fact that you may change your opinion based on the way information is phrased. Suppose you are considering a medical treatment for 600 people with a deadly illness and it has a 1 in 3 success rate. You can be told either that “200 people will be saved using this treatment” (the gain framing) or that “400 people will die using this treatment” (the loss framing).

We have now seen three broad reasons why an intelligent person may act stupidly. They may lack elements of creative or practical intelligence that are essential for dealing with life’s challenges; they may suffer from “dysrationalia,” using biased intuitive judgments to make decisions; and they may use their intelligence to dismiss any evidence that contradicts their views thanks to motivated reasoning.

This idea is, of course, no news to philosophers. Thinkers from Socrates and Plato to Confucius have argued that you cannot be wise about the world around you if you do not first know yourself.

One obvious strategy is mindfulness meditation, which trains people to listen to their body’s sensations and then reflect on them in a nonjudgmental way. There is now strong evidence that besides its many, well-documented health benefits, regular practice of mindfulness can improve each element of your emotional compass—interoception, differentiation and regulation—meaning that it is the quickest and easiest way to de-bias your decision making and hone your intuitive instincts.26 (If you are skeptical, or simply tired of hearing about the benefits of mindfulness, bear with me—you will soon see ...more

At the very basic level, you should make sure that you pick apart the tangled threads of feeling, and routinely differentiate emotions such as apprehension, fear, and anxiety; contempt, boredom, and disgust; or pride, satisfaction, and admiration. But given these findings, Feldman Barrett suggests that we also try to learn new words—or invent our own—to fill a particular niche on our emotional awareness.

you are really serious about fine-tuning your emotional compass, many of the researchers also suggest that you spend a few minutes to jot down your thoughts and feelings from the day and the ways they might have influenced your decisions. Not only does the writing process encourage deeper introspection and the differentiation of your feelings, which should naturally improve your intuitive instincts; it also ensures you learn and remember what worked and what didn’t, so you don’t make the same mistakes twice.

John Dewey wrote in the early twentieth century: “If our schools turn out their pupils in that attitude of mind which is conducive to good judgment in any department of affairs in which the pupils are placed, they have done more than if they sent out their pupils merely possessed of vast stores of information, or high degrees of skill in specialized branches.”4

Unfortunately, the work on dysrationalia shows us this is far from being the case. While university graduates are less likely than average to believe in political conspiracy theories, they are slightly more susceptible to misinformation about medicine, believing that pharmaceutical companies are withholding cancer drugs for profit or that doctors are hiding the fact that vaccines cause illnesses, for instance.5 They are also more likely to use unproven, complementary medicines.

truthiness comes from two particular feelings: familiarity (whether we feel that we have heard something like it before) and fluency (how easy a statement is to process). Importantly, most people are not even aware that these two subtle feelings are influencing their judgment—yet they can nevertheless move us to believe a statement without questioning its underlying premises or noting its logical inconsistencies.

The math required is not beyond the most elementary education, but the majority of people—even students at Ivy League colleges—only answer between one and two of the three questions correctly.23 That’s because they are designed with misleadingly obvious, but incorrect, answers (in this case, $0.10, 24 days, and 100 minutes). It is only once you challenge those assumptions that you can then come to the correct answer ($0.05, 47 days, and 5 minutes).

one experiment, in which a group of kindergarten children were allowed to watch one of their parents in a separate room through one-way glass. The parents were either asked to play with the objects on a table, to simply look at the table, or to ignore the objects completely as they chatted to another adult. Later on, the children were given the objects to inspect—and they were far more likely to touch and explore them if they had seen their parents doing the same.

attitudes that might cause smart people to develop the fixed mind-set. Do you, for instance, believe that: • A failure to perform well at the task at hand will reflect your overall self-worth? • Learning a new, unfamiliar task puts you at risk of embarrassment? • Effort is only for the incompetent? • You are too smart to try hard? If you broadly agree with these statements, then you may have more of a fixed mind-set, and you may be at risk of sabotaging your own chances of later success by deliberately avoiding new challenges that would allow you to stretch beyond your comfort zone.

Productive failure seems to be particularly fruitful for disciplines like math, in which teachers may ask students to solve problems before they’ve been explicitly taught the correct methods.

Stigler has now been researching these ideas for decades, and he suggests his findings can be distilled to three stages of good teaching:11 • Productive struggle: Long periods of confusion as students wrestle with complex concepts beyond their current understanding. • Making connections: When undergoing that intellectual struggle, students are encouraged to use comparisons and analogies, helping them to see underlying patterns between different concepts. This ensures that the confusion leads to a useful lesson—rather than simply ending in frustration. • Deliberate practice: Once the initial ...more
