Here is a hypothetical situation to think about:
You are on a trolley headed towards a split in the tracks. To the left are 5 workers who will be killed by the trolley, and to the right is only one worker. Would you pull a switch to go to the right, knowing your decision will kill the one worker?
Now here is the poll question...
Keeping in mind your answer to the above hypothetical, imagine the situation is slightly different. You are standing on a lookout above the tracks. You can see a trolley coming down the tracks, bound for a group of 5 workers who will certainly be killed by the trolley. Next to you is a man whose body is large enough to stop the trolley. Do you push him onto the tracks to save the five workers?
