# Heuristics

A relevant, real-life topic of discussion is the concept of heuristics and our tendency to sometimes ignore logic when answering questions/problem solving. Humans use heuristics (mental shortcuts) everyday, and for the most part they serve us well. We can flip through the t.v, and quickly identify what we are seeing, and decide if we want to watch it, all pretty quickly. Sometimes though, heuristics can lead us away from the truth by over simplifying and not using concrete logic. Here is an example:

There is a game show where there are three doors. One has a prize behind it and two don't. You have to choose a door, then the host will open another door to reveal a room with no prize. You must then decide whether or not you would like to choose the other door or stick with the one you already chose. Heuristics tell us that it doesn't matter which we do, we have a 50/50 chance of getting the prize. In reality you have a 66% chance of winning if you switch from your original answer. Here is a video that describes why.
