Thinking Fast and Slow

Presented at CodeMash 2015. By Joseph Ours

Joseph's presentation is based on the book "Thinking Fast and Slow" where Nobel Prize winner Daniel Kahneman introduces two mental systems, one that is fast and the other slow. Together they shape our impressions of the world around us and help us make choices. System 1 is largely unconscious and makes snap judgments based upon memories of similar events and our emotions. System 2 is painfully slow, and is the process by which we consciously check the facts and think carefully and rationally. System 2 is easily distracted. System 1 is wrong quite often. Real-world examples that demonstrate how the two systems work are that pro golfers will more accurately putt for par than they do for birdie regardless of distance and people will buy more cans of soup when there is a sign on the display that says “limit 12 per customer."
