"It's because they're stupid. That's why everyone does everything." - Homer Simpson.

Religion and nanotechnology - Boing Boing:

"Religious people seem to have a more negative view of nanotechnology than others, according to a new study. Researchers from the University of Wisconsin's Department of Life Sciences Communication rated 11 countries in Europe and the US on 'religiosity' and then looked at their attitudes on nanotechnology. Professor Dietram Scheufele and his colleagues presented their results in the scientific journal Nature Nanotechnology."

The best commentary on this, other than my obvious "Holy Jesus, are they retarded," is from the comments thread at the Boing:

"I am wary of anyone who uses fables told by nomadic bronze age peoples as the basis to make scientific judgments."
