I can't speak for ToK students specifically, since I myself did not take the IB course in high school, but I'll note that the greatest skills I've learned from this community have been a) how to state arguments clearly and effectively, e.g. not getting confused by words, and b) understanding how politics mindkills. I would love to present the Blue/Green sky dilemma, see what came of it... but only after introducing the meaning of truth and perhaps even the Litanies.
