You should know roughly how smart your closest friends and family are...
You're being disingenuous and evasive. It's a simple question. And if I had to answer, the answer would be that the people who made the most impact on my life had widely varying IQs. Some were highly intelligent, some were not. And, most importantly, what made the biggest impact on my life wasn't their intelligence, it was their capacity for love, their compassion, their friendship and their support.
Nothing to do with intelligence.
More than your parents? I'd rather have my parents around me than 1,000 Louis Pasteurs...
And you're fine with not making the cut?
