Lex Fridman  - thanks for taking up this topic.  This is an elephant in the room very few people dare to touch.   In my opinion, no topic should be taboo,  at least not in this day and age in a free world,  as long as the evidence presented is solid.   If people do not agree with the outcome,  then present an alternative view with evidence rather than banning or discrediting the discussion.,(reply>), People knows........although they don't dare talk about it, they know it's there. They just afraid to be politically uncorrect.,(reply>), Stefan Molyneux had a Youtube channel with a million subscribers, and over time he brought on 17 different career-experts in the field of human intelligence...and IQ by race/ethnicity was directly spoken to in those discussions, with IQ's correlations to social outcomes like crime/violence/brokenhomes/addiction/health/etc.  YOUTUBE KILLED HIS CHANNEL WITH NO EXPLANATION OR APPEAL.  And of course Wikipedia officially declares that Molyneux is a 'wHiTe sUpReMaCiSt'.,(reply>), @Gus Levy google how all the countries rate....makes total sense, not one is a surprise.,(reply>), @max.a.trillion The study of different types of “intelligence” is exactly where the legit research was pointing towards…but these days ANY research on g-factors and intelligence are heretical topics in academia - the irony of that is awesome, of course.<br><br>Nobody with a decent amount of reason would argue that merely having great capacity in analytical reasoning alone will guarantee success in life. That would be akin to arguing that great charisma or great athletic ability alone will make someone successful. These are mere single factors in a world where many things have to align for bettering one’s individual life.<br><br>As most of us learn through life, having great attributes helps one along life, but they guarantee nothing. Along with work ethic and luck, positive attributes merely enhance the individual’s ability to succeed in life.<br><br>Those who simultaneously focus on intelligence as the most important factor, while condemning it as non-existent when it doesn’t fit their conclusions about life, have done a disservice to themselves and the world by limiting research on intelligence.,(reply>), @Gus Levy but I find it all so much more complicated. I think there needs to be more discussion on the different types of intelligence. What about creative intelligence or ecological empathetic intelligence, spiritual intelligence, body intelligence. I've seen some really smart people who couldn't move their feet to a beat. Also is it fair to say that anyone who is a racist or bigot must surely have low intelligence. Maybe not in the measure of G. But perhaps low intelligence in the measure of empathy.
