"It is difficult to get a man to understand something when his job depends on not understanding it." -- Upton Sinclair

Imagine a preacher who has spent his entire career telling his customers "Evolution would kill god but not to worry, evolution couldn't possibly be true because creatures are very complex. Therefore they were magically created by Jeebus." Christian preachers might not use those exact words but that's what they preach.

It's impossible to convince the average Christian moron he or she shares an ancestor with chimps, and it's more than impossible to convince preachers evolution is true because then they would have to get real jobs.

But this would be an interesting experiment: What if a science-denying preacher could be locked up for 8 hours in a room with one or two excellent biology professors, for example a PZ Myers and a Ken Miller? What if the cowardly idiot was forced to understand what he has been terrified of his entire life?

After 8 hours of listening to experts patiently explain some of the massive and extremely powerful evidence for our evolutionary relationship with the other modern ape species, would this preacher be convinced?

Probably not. Stupid can't be fixed.
