I've more than average IQ thus I'm feeling I'm eligible to answer this. Movies portray many benefits of having high IQ. But they don't show the negatives of it. I'm a logical person & thus I like a analyze a situation through set of my logical abilities. My disadvantage is the ability to connect with other humans. If they feel sad or having a hidden meaning behind the thing they're expressing then it is hard for me to pick up. Also there are some unwritten social rules which I couldn't have recognized at first. I improved the ability to work with other humans like a brute-force or trial/error mechanism as if I'm trying to perform a black-box testing by giving some inputs, getting the output & then making the conclusion based on my experiments on them. I always have set of formulas & techniques to interact with other humans. Normally, I don't have much interests in pop culture movies, music or TV Series but I pretend to like & talk those things because I've seen what other humans of my age like at my college. That way I don't feel left out. I've read some neuro-chemistry to understand other humans behavior.

Ex: Dopamine is the pleasure hormone humans get from video-games, porn, drugs, sex etc. Basically anything which gives pleasure is caused by Dopamine pumping into the body. Oxytocin is the bonding & loving neuro-transmitter which gets released when we hug someone. Adrenaline released by adrenal glands when we encounter any fearful situation or stress. This results in fight or flight response. In forest when you encounter any dangerous animal, you either run or you fight. This is adrenaline in action. Human males have 10x more testosterone than human females. Testosterone is aggression hormone. And aggression is directly tied to sexual activity. Thus, human males thinks about sex 10 times than human females.

So the major challenge with having a high IQ is my low level ability to empathize & connect with others. And to cope with this & to further understand others behavior, I study Biology & Psychology on regular basis.
