Fascinating watch.  Cannot stop laughing at Lex's fear of truth and fear of increasing intelligence at a possible cost of happiness/empathy/blah/blah lol<br><br>Gotta laugh at Lex's fear of increasing one's intelligence having a neg impact on happiness, in decades of observing human behavior my narrow slice of observations with zero clinical/study data as backup, I see folks that have figured out what makes them happy being happy, and folks that have not figured this out being unhappy.  May sound simple but most things are when the task is appropriate for one's IQ, and this one topic appears to be in range for those I have observed.  Have to give props to the author of the 7 Habits of Highly Effective People for helping me figure this out in my 20's and 30's.<br><br>On separate topic, could the discussion or sharing of the genetic differences in IQ cause racism or hate?  IMO, no, I do not believe truth as a cause of racism or hate.  I see hate as an emotional /chemical response to another human's output.
