Dumbly and happily bumbling about for a bit

A well enforced and highly praised theme in this education program is reflecting. Though I see the benefits of reflecting on a person with a somewhat well developed sense of self, and a decent amount of self confidence, I wonder about the validity of using reflections for students. I think that heavily enforced and chronic reflections on students with not yet fully developed senses of self would lead us to form a generation of highly introverted citizens.
Now let us look at this assumption in a statistical sense. The high tail end would have some students with good self-confidence, and reflections would aid them in learning from their own mistakes. On the low tail end there would be a population that is so introverted and unsure of themselves that they become total social recluses. The majority, of course, would lay somewhere between these two extremes. But none-the-less, they would be somewhat more likely to be introverts, and on top of that critical introverts. What ever happened to just creating something and then enjoying the moment… not necessarily analyzing the thing to death, but just dumbly and happily bumbling about for a bit? Humm… maybe that’s the appeal of such movies as Jackass… maybe stupidity is not such a bad thing?
Or am I just being stupid and assuming too much? - to you my readers: feel free to poke holes in this 'theory'.
