Bayes’ Rule and Athletes Doping

Years ago, scientists wanted a sure-fire method of catching professional athletes who use doping to enhance their performance. However, scientists are not always able to easily detect these drugs in a given athlete’s system.

Big Data: A self-fulfilling prophecy?

Something I found interesting about prediction markets was the idea of the self-fulfilling prophecy, and how it can be embedded into network behavior and the outcomes that manifest because of it.
