High IQ creates barriers that can prevent one from experiencing the social situations that enable the development of social skills. And when you are left behind in social skills, past a certain age, people show much less tolerance for your quirks, and basically think that if you are that way, you must be weird/ have a problem and will not tell you honestly what is the issue with you. Giving somebody with subpar social skills social cues serve no purpose, as they don't get any benefit out of it. So you get a catch 22, as you don't have sufficient social skills to know / get the help needed to develop your social skills.
