This is my take on the subject:
- Evolution is pretty intuitive IMO, but it sits completely in opposite to the biblical beliefs, so it's hard for people to believe in it (it's not fun being raised a certain way just to one day understand everything you were taught it wrong).
- The big bang theory is not only very counterintuitive, but both defies the bible AND requires a very big understanding in fields like astrophysics and relativity in order to grasp - so it's very reasonable for people to question it (most people would rather believe simple and comforting ideas rather than doing long research and realizing that the universe is much more complicated the we used to think.
- Global warming, like TBBT, is very difficult to wrap your head around. Not only that, but it makes people feel like they have to make significant changes in their lives in order to fight it - something most people despise. It's easier to believe things aren't as bad as the weird science dudes tell us. Also, there are plenty of big corporations that are afraid of losing money if people start changing their habits (mainly oil companies), so they do whatever they can to make people question global warming. But TBH, I think this is the least controversial one of the three, because it doesn't disagree with religion.
I guess the bottom line is people mostly believe things they like to hear - simple and intuitive truths that make them feel like they're the center of the universe and like everything's gonna be a-okay, no matter what they do. Smart people do that too - even Einstein didn't belive in quantum mechanics at first because it was just so counterintuitive.
And just to set things straight - I agree about Bach, Beethoven and Brahms
