There is a correlation (though that does not imply causation as the saying goes) between folk who form opinions based on evidence (such as that presented by science for example) and those whose opinions are formed by ideology. Left-wingers tend to be more evidence-based than right-wingers and the religious. There are exceptions of course, but if you look at the way the threat of climate change (for example) is treated by right-wingers (wrong, hoax, deny, etc) then they totally ignore the available scientific evidence, as will a UK tory when it comes to the percentage false benefit claims.

This dichotomy is responsible for the mess the western powers have allowed their countries to get into by allowing markets to dictate policy where possible. There's no doubt if you give people free heath care they will live longer and suffer less whilst alive, yet many right-wingers (especially in the US) don't care if people do die young and suffer needlessly because they believe an inability to pay is a sign of weakness.

As for religion, whatever the more fanatical religious folk on this site say there's zero scientific evidence to support any of the creation theories, existence of god, the devil or the flying spaghetti monster. If personal revelation tells you it's true then fine, but don't go pretending science supports your supernatural interpretation of the world; it doesn't. That said, many people's faith (including scientists) is thankfully a little more sophisticated than the fundamentalist headbangers absolutist claptrap. We all know how that ends.
