GoKawiilBlogger recounts pulling emergency brake after misjudging subway door incident
A writer recounts an incident roughly eleven years earlier on a subway's Red Line, where he pulled the emergency brake believing a passenger's arm was trapped in a closing door as the train began moving. The man freed his arm once the train stopped, though his bag remained caught; another passenger who was closer to the scene later said it looked like only the bag, not an arm, was stuck in the door. The writer says the episode resurfaced in conversation at an effective altruism dinner and prompted him to compare it with philosophical thought experiments like the trolley problem and Scanlon's Transmitter Room.
