This is a research performed at Harvard, Princeton and M. I. T about smart people. Just an extract though I couldn't copy all because of lazy readers. Lol!

1. Smart people are overconfident. A lifetime of praise and pats on the back leads smart people to develop an unflappable faith in their intelligence and abilities. When you rack up accomplishments while people stroke your ego, it’s easy to expect that things will always go your way. But this is a dangerous expectation. Smart people often fail to recognize when they need help, and when they do recognize it, they tend to believe that no one else is capable of providing it.

2. They push people too hard. Smart people develop overachieving personalities because things come so easily to them. They simply don’t understand how hard some people have to work to accomplish the same things, and because of that, they push people too hard. Smart people set the bar too high, and when people take too long or don’t get things quite right, they assume it’s due to a lack of effort. So they push even harder and miss the opportunity to help others achieve the goals they’re so anxious for them to reach.

3. They always need to be right. It’s hard for anyone to graciously accept the fact that they’re wrong. It’s even harder for smart people because they grow so used to being right all the time that it becomes a part of their identity. For smart people, being wrong can feel like a personal attack, and being right, a necessity.

4. They lack emotional intelligence. While intelligence (IQ) and emotional intelligence (EQ) don’t occur together in any meaningful way (Smart people, on average, have just as much EQ as everyone else), when a smart person lacks EQ, it’s painfully obvious. These high-IQ, low-EQ individuals see the world as a meritocracy. Achievements are all that matter, and people and emotions just get in the way. Which is a shame because TalentSmart research with more than a million people shows that—even among the upp

Accurate.
