Irrational thinking

Great talk at the Truro Grand Round today on irrational thinking, cognitive bias, and generally things psychological that affect medical decisions and the behaviour of healthcare professionals.

It included this classic video of selected attention. Basically it was introduced as follows - "There is a gender difference in detailed attention. Watch this video very carefully and count exactly how many times the white team pass a basketball to each other. They will move around a lot so count carefully and we'll see who does better - male doctors or female doctors."

About half of those in the room had excellent sensory attention and the other half, including me, did not notice one thing in particular.

Other topics covered were:
The Monty Hall problem
Thinking, Fast and Slow. Daniel Kahneman
The hidden Dalmatian dog illusion
