3.You might not learn the value of hard work
A number of Quora users mentioned that intelligent people feel like they can get by with less effort than other people. But a high IQ doesn’t always lead directly to success, and highly intelligent people may never develop the perseverance required to succeed.
According to Kent Fung, “Intelligence becomes a problem when those who have it discover early in life that they don’t need to work as hard to keep up, and thus never develop a good strong work ethic.”
One study found that conscientiousness — i.e. how hard you work — is in fact negatively correlated with certain types of intelligence. The researchers propose that highly intelligent people might feel like they don’t need to work as hard to accomplish what they want.
4. People may get annoyed that you keep correcting them in casual conversation
When you know that someone’s just said something completely inaccurate, it’s hard to stifle the urge to clarify. But you’ve got to be extremely sensitive to the fact that other people may be embarrassed and offended by your actions — or risk losing some friends. Being intelligent is a bummer, says Raxit Karramreddy, “when you correct people each and every time to a point that they stop hanging around with you or stop talking with you.”
5. You tend to overthink things
A common theme in this Quora thread was the pitfalls of spending too much time contemplating and analyzing. For one thing, you may get maudlin when you try to find the existential significance of every concept and experience. “You realize how moribund everything is and that nothing really means anything. You search for answers and it drives you crazy,” writes Akash Ladha.
Indeed, a widely covered study published in 2015 found that verbal intelligence really is linked to worry and rumination. From a practical standpoint, all that perseveration means smart people may find it impossible to make a choice. Tirthankar Chakraborty writes: “An understanding of the possible ramifications of your decisions, especially the tendency to over-analyze those consequences, makes it so that the decision is never taken.”
6. You understand how much you don’t know
Being super-intelligent often means appreciating the limits of your own cognition. Try as you might, you’ll never be able to learn or understand everything. Writes Mike Farkas: “Intelligence is a curse when … the more you know, the more you feel the less you know.”
Farkas’ observation recalls a classic study by Justin Kruger and David Dunning, which found that the less intelligent you are, the more you overestimate your cognitive abilities — and vice versa.
In one experiment, for example, students who’d scored in the lowest quartile on a test adapted from the LSAT overestimated the number of questions they’d gotten right by nearly 50%. Meanwhile, those who’d scored in the top quartile slightly underestimated how many questions they’d gotten right.
