Funny but the stereotype is the opposite from the 60s. As the saying goes

If You Are Not a Liberal at 25, You Have No Heart. If You Are Not a Conservative at 35 You Have No Brain

Note: I'm not conservative and I don't necessarily agree with the quote. The point is not that the quote is correct, the point is someone (not me) thought it was the unthinking young person that thought alone liberal lines and the experienced wise person that thought along conservative lines.

Again, not agreeing, just pointing out some feel the opposite, that more experience and exposure to the world leads to more conservative thinking for some people.

I believe there is some evidence to suggest that there was a mistaken correlation between getting older and getting more invested in the world as it is (i.e. getting richer).

Given that the age at which people tend to switch is increasing, I wonder if there may be something to it.
