It takes a lot of effort and you don't see immediate results. I'm sure most people have encountered book-smart individuals with neither common sense nor social skills. Or pretentious types who read a few chapters of Kant and feel the urge to let everyone know how philosophical they are. There are loads of people who learn a little rationality and act as though they are perfectly logical beings. Pedantry, arrogance, and pretentiousness trap many a beginner; such types make poor ambassadors. This essay, for example, got me to really reflect on my writing style and how I was presenting myself.
In short, people are liable to generalize from bad examples and associate rationality with quarrelsome pedants spewing forth incomprehensible jargon.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
