That's the kind of people mensa attracts. Gifted people are often highly emotional. If you're gifted in one respect you are more likely to be gifted in another. Some are intellectually gifted. Some are emotionally gifted. Many are both. And I believe the chances that you are both increases as you move from gifted to highly gifted to profoundly gifted.
The smartest person in the room will more often be a MENSA type, the smartest person in the company will more often be gifted across the board.
