I think that the extra light from the moon does have an impact on things like crime rates... and in a similar vein, on baby sleep (if there are no blackout shades). But I don't believe it has an impact on human behavior.

Although that said, there was a full moon on the site two days ago and the boards have been a bit angst-y lately! So maybe the full moon really does affect people?

Do you believe in the full moon... i.e., that a full moon affects human behavior?
