Does society put more value on a person's intelligence now than it did 50 years ago?
Not at all. If we valued intelligence, we'd put much more time and effort into education. Most people would then understand simple concepts like vaccines, evolution, and the greenhouse effect.
How do you explain the infatuation with the Kartrashians?
Actually put less emphasis on it. Look at the huge push now to squash scientific thought. There is a huge undercurrent of anti-intellectualism in this country.
