A thought experiment.
You heard of the Milgram experiment? Well, this is something like that. Imagine you're taken into the laboratory of a mad but very wealthy scientist. She wants to run a social science study. She sits you down in front of a chair, where she has an innocent victim strapped down to a mess of electrodes. She gives you a device with a button to push. If you push the button, two things happen. First, the victim (you don't know him, but he kinda reminds you of a nice guy you went to school with) dies a horribly painful death right in front of you (it takes, like, 30 minutes). Secondly, an ATM slot opens up and gives you US$10. You can of course instead press the "no" button, in which case nothing happens. Except that a counter displaying your reward for pushing the murder button goes up a significant figure -- and now you get another round of playing the game. This time, the figure is US$100. Every time you decline the offer likewise increases, to a maximum of US$1,000,000,000. (The mad scientist will help you convert this amount into your local currency or an untraceable offshore account or whatever suits your needs. She's very friendly and helpful that way.)
The victim, of course, is going to beg and plead and please don't do this to me for God's sake!! ! Remind you that he is a human being with a family. His mother needs him. Tell you about the wonderful girl he's in love with. Feebly grip your arm. The mad scientist promises you (you somehow know she's always telling the truth) that if you refuse to take the offer for any amount of $$$$$$$ the victim will be released with no harm done. You'll also lose your only chance at the money. Also you know (let's assume) that's there's absolutely zero chance you will be caught or held accountable in any way for this. So if you kill the victim, he'll scream in agony and you'll have to watch the whole thing without turning away. But no one except you will ever ever know.
Let's assume a few other stipulations. Any money you get has to be spent on you. Meaning your personal goals and lifestyle. You can afford that university degree, start a business, travel the world, migrate to a better place, get a sweet apartment in the city of your choice, get any clothes/food/medical care/drugs/toys/wild sex parties you ever wanted. But you can't spend it to help people, or give to charity, or save refugees, or mitigate climate change. Yes, there's an impossible grey fuzzy line here (does pursuing the partner of your dreams and making him/her happy count as selfishness or altruism? IDK) but the mad scientist's point is she doesn't want you to take the money for utilitarian reasons that taking one life will give you enough money to save many others. The idea here is how much it will take to get you to watch someone die purely for your selfish benefit. She cheerfully reminds you that they did a study which said 1 in 14 Americans admitted they'd murder someone for US$3,000,000. But you don't have to be like that if you don't want to.
Oh, and you can't kill the scientist, rescue the victim, report the evil laboratory to the authorities, or just steal the money. Our social scientist approves in principle of trying to take a third option but in this case she's covered the bases to make sure you face the question. So, here's the button. Cash dispenser in the front drops the bills directly into your lap.
Please select how much has to be offered before you decide to push the button. This poll is completely anonymous and no one will ever judge you for your feelings. One vote each. (the mad scientist would appreciate if you refrain from voting if you don't think you're on the autism spectrum)
