Can't say I agree, Socrates figured it out thousands of years ago!
>Unfortunately, we don't really know how to do this. Longitudinal studies of critical thinking skills across 4 years of college show a modest improvement but there are caveats [1]. For one, the usual courses you'd expect to improve critical thinking (logic, philosophy, statistics) don't do very well.
I'd argue that these courses are, at best, tangentially related to critical thinking. We need to teach the Socratic Method of learning to children from day 1, in all areas of study. Teaching children how to think and how to be intellectually curious is ultimately far more effective than our current methods if your desired result is an informed and intellectually capable populace.
