Well, finally science has something to say about the conservative mindset or brains. They are really limited according to a new study of the New York University and UCLA:

Previous psychological studies have found that conservatives tend to be more structured and persistent in their judgments whereas liberals are more open to new experiences. The latest study found those traits are not confined to political situations but also influence everyday decisions.

…

Based on the results, he said, liberals could be expected to more readily accept new social, scientific or religious ideas.

So why are these people allowed to vote - if they have such a hard time to adopt to change and new situations? In an ever changing world we need leaders (and voters) that can cope with change!
