An interesting article

in this weeks Spectator by Cass Sunstein, co-author of Nudge (which I need to find my copy of and read sometime soon).

It certainly seems true to me going to an event and talking to people with a similar viewpoint does tend to reinforce my views, I also find I tend to stay on the same websites/blogs and not visit ones that would challenge my opinions. On the other hand I spent 3 years at a very leftist dominated university and still ended up a classical liberal, so maybe there's more to it than peer pressure
