In chapter four I found the section about extrasensory perception (ESP) very interesting. There have been many, many studies done that try to prove that ESP exists. Joseph B. Rhine's research proves inaccurate because his results were not able to be replicated. Rhine used these cards in his research. Also, it was found that in Rhine's experiment that they did not completely randomize the cards, which causes a lot of biases in his experiment. I found this very interesting because I would have thought if they would have caught this major mistake a lot earlier.

In this article by Benedict Carey explains how recent studies on ESP caused a lot of chaos. Some scientists think that the this report only shows the flaws in evaluation. I found it very interesting that so many scientists had such strong opinions on this topic. Many scientists think that claims that defy almost every law of science are by definition extraordinary, therefore there needs to be extraordinary evidence.
