This is an interesting study they have conducted. But in truth, I think it really depends on what exactly is the content of the secret, the personality of the person being told the secret, as well as the relation between the two people sharing the secret. I agree that 3000 women isn't really that large of a sample space. They probably are ignoring data from the introverts >>
*gasp* our secret is out... not really, to be honest, all woman know that's the truth, we just accept and turn a blind eye on it lol.
