Hm... in the trolley problem at least one person gets saved, but if you don't lay off a person and the company goes bankrupt, everyone is out of a job, so that makes the choice much easier. And even if you could formulate the problem so it really was a choice between 1 person getting fired or 5 other people getting fired, that would be easy; it's obviously better to fire just one (at least, as long as you don't know anything else about the people - for some people getting fired would be a bigger problem than for others).
I wished for an example without killing, but maybe it is essential to the problem, after all. I guess the choice would at least have to make you do something you'd normally consider immoral, like stealing or lying, else you'd just say 'oh, harm only one vs. harming several, easy choice'.
Why don't we have Life Hack thread like we do have Media Threads and Rationality Quote Threads?
Well, now we do.
I'm copying in the comments some hacks previously written about by others for your convenience, also check out the Munchkin post if you haven't, there are many interesting hacks there. Timewise, I've made it quarterly because it is harder to face a life hack than it is to face o quote, so less frequency may improve average quality. Below is a suggested description for them with structure taken from media threads. Any further ideas on how to improve the thread are welcome and should be made at the Metathread tree.
This is the quarterly thread for posting Life Hacks of various types that you've found that you enjoy. Four main thread-trees will be in the comment section.
1) There is substantial evidence for it (please post pointers to it)
2) I tried/ Friends tried/ There is some small evidence for it
3) Seems like a cool idea
4) Metathread
