In psychology and logic, rationalization (also known as making excuses) is an unconscious defense mechanism in which perceived controversial behaviors or feelings are logically justified and explained in a rational or logical manner in order to avoid any true explanation, and are made consciously tolerable – or even admirable and superior – by plausible means.

Searle’s experiment supposes that there is a program that gives a computer the ability to carry on an intelligent conversation in written Chinese. If the program is given to someone who speaks only English to execute the instructions of the program by hand, then in theory, the English speaker would also be able to carry on a conversation in written Chinese. However, the English speaker would not be able to understand the conversation.

Outside of the domain of traditional philosophical discussion, the trolley problem has been a significant feature in the fields of cognitive science and, more recently, of neuroethics. It has also been a topic on various TV shows dealing with human psychology.

The general form of the problem is this: Person A can take an action which would benefit many people, but in doing so, person B would be unfairly harmed. Under what circumstances would it be morally just for Person A to violate Person B’s rights in order to benefit the group?
