Once again, social science has done what it so often does: Proven that which we already knew deep in our souls.

In this case, it’s that Facebook is bad for us.

In the June edition of the journal Computers in Human Behavior actual peer reviewed studies proved that thesis.

The first showed that the longer people are on Facebook, the worse the mood they were in afterward.

The second showed that that’s in part because being on Facebook leaves people with a feeling – and this is a quote – “of not having done anything meaningful.”
