Confirmation bias is huge. I'm glad they're trying to tackle it.
I think the trend of overconfidence in the magic of Scientific
Method to automatically correct human bias may be part of the
problem.
Psychology has gotten more and more poo-poo'd as an unScience
through the years.. and some BASIC Psychology such as "yes
you're Human, Scientist and you _have_ bias" is more freely
tossed aside, skewing results.
