james_nicoll points out this blog post on technological and scientific optimism among different groups, mostly varying by education, though age differences are implied as well. the blog post is associated with this survey of sci/tech optimism. i recommend that if people are interested in seeing how optimistic they are compared to others that they take the survey before reading the blog post or james' commentators' discussion of it.
