There are a few exemptions -- primarily for psych experiments, where giving away the true nature of the experiment ahead of time could invalidate the results. (For example, the Milgram experiment -- which researched how much a person would harm another if someone in authority tells them to do so -- wouldn't have provided valid results if you were told ahead of time "Each time you are told the person on the other side got an answer wrong, you will turn up this knob a bit and push this button, and we'll play a recording of someone pretending to get increasingly severe shocks.")
