Two awards did stand out for me personally

1) The psychology award about

"People who stay up late into the night are, on average, "more self-admiring, more manipulative, and more psychopathic" than people who habitually wake up early in the morning"

Makes me wonder how much more manipulative am I really? (Rhetorical question. Please don't answer…)

2) The public health award about

"… investigating whether it is mentally hazardous for a human being to own a cat… owning a pet cat may have some effects on human personality, from lower intelligence in men to feeling less guilt in women."

Keep in mind these are research to make people laugh first ( http://www.improbable.com/about/)
