It may be a valid and interesting result, but I don't think it was ethically collected. I'd love to hear how these human subjects were briefed or compensated for this study. It's pretty clear the professor was subjecting them to unexpected emotional stress without their consent. It may also be valid and interesting to find out what happens if you flip people off in traffic, or pay for your restaurant bill in pennies, or taunt preschoolers when you beat them in a game, but it doesn't mean it's ethical to just go out and do it, even if there's nothing explicitly saying it's illegal.
