Dr.Ziesche calls for more globally accessible rationality training. He seems supportive of existing efforts, especially us, but thinks it would be nice if rationality training was easily accessible to people other than educated westerners.
This is something both the author and most Less Wrongers (including myself) assume, but we really don't have all the much (scientific) evidence for this belief (that I know of).
I am sceptical that you can teach rationality on its own in school as just one more subject in the curriculum. It needs to be folded in to every other subject, and then maybe some classes focussing on rationality itself will be useful.
