The Time Traveler

There’s an out of control trolley speeding towards a worker. You have the ability to pull a lever and change the trolley’s path so it hits a different worker. The different worker is actually the first worker ten minutes from now.

The Cancer Caper

There’s an out of control trolley speeding towards four workers. Three of them are cannibalistic serial killers. One of them is a brilliant cancer researcher. You have the ability to pull a lever and change the trolley’s path so it hits just one person. She is a brilliant cannibalistic serial killing cancer researcher who only kills lesser cancer researchers. 14% of these researchers are Nazi-sympathizers, and 25% don’t use turning signals when they drive. Speaking of which, in this world, Hitler is still alive, but he’s dying of cancer.

The Suicide Note

There’s an out of control trolley speeding towards a worker. You have the ability to pull a lever and change the trolley’s path so it hits a different worker. The first worker has an intended suicide note in his back pocket but it’s in the handwriting of the second worker. The second worker wears a T-shirt that says PLEASE HIT ME WITH A TROLLEY, but the shirt is borrowed from the first worker.

The Ethics Teacher

There’s an out of control trolley speeding towards four workers. You are on your way to teach an ethics class and this accident will make you extremely late. You have the ability to pull a lever and change the trolley’s path so it hits just one person. This will make you slightly less late to your class.

The Latte

There’s an out of control trolley speeding towards five workers. You’re in a nearby café, sipping on a latte, and don’t notice. The workers die.

The Dicks

There’s an out of control trolley speeding towards two workers. They’re massive dicks. You have the ability to pull a lever and change the trolley’s path so it hits just one person. He’s an even bigger dick.

The Business Ethics Version

There’s an out of control trolley speeding towards three workers. You have the ability to pull a lever and change the trolley’s path so it hits a teenager instead. At a minimum, the three workers’ families will receive a $20,000 insurance payoff each, and the families will no doubt sue the company, which in this scenario you represent. The trolley driver seemed to die instantly from a freak aneurism, so your company might not be faulted for negligence under the FELA and might come out okay. The teenager’s parents, on the other hand, make a total of $175,000 a year, and can afford a pretty decent lawyer.

The Real Stinker

There’s an out of control trolley speeding towards four workers. You have the ability to pull a lever and change the trolley’s path so it hits just one worker instead. But get this: that one worker? It’s your fucking mom. Bet you weren’t expecting that shit, were you?

The Surrealist Version

There’s an out of control trolley speeding towards four workers. You have the ability to pull off your head and turn it into a Chinese lantern. Your head floats into the sky until it takes the place of the sun. You look down upon the planet. It is as small as the eye of a moth. The moth flies away.

The Meta-Ethical Problem

There’s an out of control trolley speeding towards Immanuel Kant. You have the ability to pull a lever and change the trolley’s path so it hits Jeremy Bentham instead. Jeremy Bentham clutches the only existing copy of Kant’s Groundwork of the Metaphysic of Morals. Kant holds the only existing copy of Bentham’s The Principles of Morals and Legislation. Both of them are shouting at you that they have recently started to reconsider their ethical stances.
