The way I see it, Jews are generally well educated and highly intelligent people. However, a lot of people who go to university/college, can become too intellectual and loose some "common sense". Look at the way liberals/socialists dominate universities. These people don't live in the real world. Every culture has folk tales of the peasant who is looked down on by the intellectuals, but who triumphs by having more common sense. It's the difference between knowledge and wisdom. Of course, I suppose it's more of a problem with non religious Jews, as The Bible is the greatest source of wisdom in the world.
