There were a few significant demographics differences here. Women tended to be more skeptical of the extreme transhumanist claims like cryonics and antiagathics (for example, men thought the current generation had a 24.7% chance of seeing someone live to 1000 years; women thought there was only a 9.2% chance). Older people were less likely to believe in transhumanist claims, a little less likely to believe in anthropogenic global warming, and more likely to believe in aliens living in our galaxy.

This bit is interesting. If our age and gender affects our beliefs than at least some of us are doing it wrong. Update accordingly. I'm young and male, so I should give less credence to global warming and more credence to nearby aliens.
