One fifth of humans say aliens walk among us http://www.theregister.co.uk/2010/04/12/alien_survey/ There's something very interesting going on here, but it's probably not about whether aliens are real and whether they're really walking among us. Purely from a socialogical point of view, what is going though people's heads and why do they believe this stuff? Or is it just about people's reactions to ridiculous surveys and a quirk in the statistics. In other news, a recent survey showed that 80% of mammals reckoned humans are from another planet.
