A friend's been telling me to read a controversial book called "The Bell Curve" about the genetic basis of intelligence. The reason the book's controversial is that it builds a case that intelligence has a genetic basis, and some races are smarter (on average) than others (although there's tremendous individual variation, and environment / upbringing plays roles too). If that's indeed the way the world actually is, would that be a truth our society could accept? On the one hand, I'm no racist, nor do I aspire to ever be one. On the other hand, I want to say that I aspire to a proper scientific worldview, understanding the world according to evidence and reason. If I dismiss The Bell Curve's argument, am I being properly skeptical of unproven claims, or am I just going along with societal pressure and my own wish to live in a world where race really doesn't matter?
