He's a Professor of Economics at GMU, and is probably one of the top 10 most popular econ bloggers on the web.
If you want the scholarly version, skip the blog post and click through to the original paper (which was discussed on HN previously but I can't find the thread).
Page 26 of the paper does cite a study showing that libertarians have higher SAT scores, but that's probably not the only reason Caplan blogged it.

The Liberty Fund doesn't engage in political advocacy. They primarily (re)publish literature important to classical liberalism and the moral case for liberty (and history and law, etc). They also put on occasional conferences, and they maintain online libraries.

How is that not political advocacy?
If a Socialist site 'republished literature important to classical Socialism and the moral case for social equality' would you not consider it a political entity?
The website is the Library of Economics and Liberty and is funded by The Liberty Fund,[1]. In my brief review they appear to advocate for modern libertarian ideology. Does anyone know more about them?
At least, this seems to be political advocacy and not scholarly analysis. (I'm not criticizing it; just trying to understand what I'm reading.)
