Godfuckingdamnit. This is syntax class all over again, isn't it? It's damn obvious, but there's some people who did actually need to solve the trolley problem, and still didn't.
My experience with syntax is that we wasted 10s of hours learning concepts that we pick up naturally, that no one would ever need to analyze it with this much detail just to be able to properly speak their native tongue (Spanish in my case). As it turns out, there's plenty of people who have been speaking Spanish their whole lives and still manage to fail somehow.
The original trolley problem is extremely simple and no person should be dumb enough not to save the maximum amount of people. And yet there's plenty of people who feel icky at the prospect of having to take a decision. And yet.
