Just a little bit mad
Why is it unethical?
First of all, no psychological experiment should be carried out by a news organization. Second, the original experiment did not have sufficient debreifing. Third the experiment involves deciving a person that they had hurt a person. Deception is in itself enough to make an experiment unethical.
Besides, this experiment was carried out by a news organization, if I have understood correctly. This is absolutely inexcusable to conduct such experiment if your only goal is to create a news story, and such experimentation is banned by international treaties.
