Not very long ago there was a story posted about some boys from a Catholic boarding school in New Zealand(?) who got lost on an island and how it did not turn into Lord of the Flies. I'll try to find the link, but generally I'll advice to take both science and highly praised fiction (as well supposed debunking of science) with a healthy dose of scepticism.
