Study: Are Liberals Smarter Than Conservatives?
Infinitely. Conservatives act according to what they've been told, and what has been done before, whereas Liberals think for themselves, and try to look for new solutions. It takes more brain power to think original thoughts than to follow engrained precedent.
Unfortunately, it's also the political weakness of liberals. If you all think for yourselves, you will be less likely to all vote in lock-step. On the other hand, conservatives, all doing what they're told and as precedent dictates, will vote as they're obliged, and so they have greater political power at the polls by the monolithic nature of their unthinking obedience. If you all think alike, you will all vote alike, and that blind fanaticism will always give right-wingers an edge in politics.
