Bushman (Bushman and Huesmann 2012) tested the impact of watching a violent video on students’ level of aggressiveness. He found that watching the violent video increased aggressiveness. Do you consider it ethical to expose subjects to an intervention that might increase their aggressiveness? Are there any situations in which you would not approve of such research? Any types of subjects you would exclude from such research? Any limits you would draw on the type of intervention that could be tested? Would you impose any requirements for debriefing?
