Facebook stepped over an ethical line in their "research". No, nobody got (badly) hurt but that doesn't make it acceptable.
Yes actually it does make it acceptable because the people doing the experiment knew that it was very very unlikely to cause anyone serious injury. When an psychological experiment amounts to no more than making people aware their buddies had a shitty day at work by their own account, I don't think it actually rises to the level of requiring consent.
Humans conduct experiments all the time; its how any self aware being interacts with the world around them. It just on a small scale so nobody cares, I bet plenty of sales professionals have at leas t informally experimented around if asking about peoples kids, helps them close deals. If every little experiment no matter how benign really requires informed consent then all anyone will have time to do ever again is sue each other over if their actions constituted an experiment or not.
