Do you think children's environments are more geared towards extroversion rather than to personal reflection ?
Here's a very thoughtful TED talk about the important of introverts in our constantly chatting world: http://www.ted.com/talks/susan_cain_the_power_of_introverts.html

I've actually written something based on Susan Cain's ideas for the site before, and I would say: yes! Definitely! At school if children are reluctant to interact with their peers or answer questions in class this is seen as a negative thing that needs to be "improved" rather than just a part of their personality, and they are pushed into doing things that they're uncomfortable with. Which can be hugely damaging, as Cain has talked about: you're basically telling people that being shy and retiring is "wrong" so, if you tend to the introverted than the extroverted, there's something inherently wrong with you.
That said...there is plenty of evidence to suggest spending long periods of time alone is bad for your health. Plus, the world is geared towards extroverts, so perhaps there's something to the fact that we try and prepare kids for that. Whether that's pushing them to interact more at school, or in the playground, or to take them on playdates etc
