INCENTIVES: “Assume you are a teenager contemplating suicide. If you knew the 9 kids at school who were meanest to you would get criminally prosecuted if you killed yourself, would you be more likely to kill yourself or less? I don’t know enough about the psychology of suicide to answer my own question, but my intuitive sense is that self-murderers — or some self-murderers — intend to deal a severe blow to the people they leave behind. And knowing your enemies will be prosecuted might spur you on.”
