Contagious research

From The happiness virus :
"It’s too good an idea to resist: Happiness is contagious. A new study published online Dec. 4 in the British Medical Journal shows it.

Maybe you’d be more inclined to resist these ideas, though: Headaches are contagious. Acne is contagious. Height is contagious.

According to another study published the same day in the same journal, by Ethan Cohen-Cole of the Federal Reserve Bank of Boston and Jason Fletcher of Yale University, these latter claims are nearly as likely as the first. The researchers “proved” them using the same methodology."
