It takes a high IQ to evade the obvious

From The Multicultural Cult, an essay by Thomas Sowell. I have long enjoyed Mr. Sowell's common sensical approach to issues and his commitment to deep research and analyzing topical concerns from the perspective of what the data allows us to know rather than the perspective of what we would wish were the case. Here is a passage where he goes beyond the data and ends up channeling P.J. O'Rourke:

In Germany, as in other countries in Europe, welcoming millions of foreign workers who insist on remaining foreign has created problems so obvious that only the intelligentsia could fail to see them. It takes a high IQ to evade the obvious.
