File under Ghost's guilty pleasures, a fat and growing file to be sure, but I'm sorry to admit, I greatly enjoyed the current mainpage FA on Confirmation bias. In fact it is one of the best FAs I've read in many moons. It is cogent, coherent and comprehensive. It doesn't read like it was written by a committee of IB students, nor is it a Franken-article of a bunch of cites stitched together. Even more impressive is that it is on a subject that is not one of the "pedia's" fortes (Pop-culture, Mil History or Bizzaro) but, rather, on one which it seems to be rather weak (at least judging from comments over the years by experts in the area).
Admittedly, cognitive science is not my forte either, but I know several here are well versed in that fascinating field of study (or at least better versed than I), so I'd appreciate their unbiased opinions of it.
