Intelligent people are usually more idealistic, and liberalism often appeals to that.
However, my college, Georgia Tech, has some of the most intelligent kids in the state, and we have a great variety of political ideologies. The professors don't really preach ideology. Fortunately for me, it also reflects the Tech sector in that there are more people who are friendly to the libertarian ideology - probably because engineers and programmers tend to think in logical terms rather than emotional ones.
I'm a programmer who tends to think in logical terms rather than emotional ones and I got led to liberalism (albeit a moderate form). I know you'd like to think that libertarianism is the most logical choice, though.
