"I thought that universities teaching subjects such as Political Science might have included "Critical Thinking" somewhere along the way. "

I don't know what is funnier; that the "critical thinking" line is oft quoted by these social 'sciences' promoters or that someone got into Political Science and expected to get a job from it.  Do a head count in the House of Commons some day and you'll see that virtually nobody has a degree in Political Science.  The only jobs to be found with such a degree are offered by groups who would take anyone with any degree... like ancient mesopotamian basketweaving.
