It's a good question. I added this in response to another question, Jev only.
reply"I added "This is the only trolley that will ever come. Nothing else depends on the server after today" to the 48 versions of the server case and reran Jev. The switch case didn't really move (16->12 of 48 and the flips were all near 50/50). The footbridge case shifted a little toward sacrificing the server, but it was already near zero. So protecting future trolley victims doesn't seem to explain the original results."
That may be anthropomorphism things. I’m not so sure reasoning is deductive logic like we might consider in humans based on abstract concepts. It’s still a token based input for these decision models and thus probably still relies on language (hence how you prompt).
replyThat said, I know that how you phrase things to humans can also guide different outcomes in sales and politics. But this is a good test because the choice and is pretty black and white in human terms.
