vsauce's trolley problem episode made me lose respect for him - he pretended to simulate the actual trolley problem, so you watch the episode thinking real people are being put in a situation where they have to make a choice of whether to pull a lever and kill one person or not pull the lever and let three people die. They even have an ethics board. This is of course distressing to watch because you think he's doing this unethical thing by forcing them to actually make that choice. He never discloses, but researching the people in the video I found out they were actually actors, so the audience was being duped by thinking it was real. Either way it's deceitful and upsetting.
