Two year old Nicholas solves the trolley problem by treating everyone equally.
His dad, E.J. Masicampo, says:
I’m teaching a moral psychology class this semester, and we spent part of the first day discussing the trolley problem, which is a frequently used ethical dilemma in discussions of morality. When I returned home that night and was playing trains with my son, I thought it would be interesting to see his response to the trolley problem. I recorded his response so that I could share and discuss it with my class, given especially that we also will be discussing moral development from birth onward. My wife and I are constantly talking with our son about how properly to treat others — so this has been teachable moment both for my class and for our son!
