This book begins by describing the difference between psychology and science. I found this section interesting because initially I was a little confused between the two. However, this wasn't the most interesting section to me. Later in the chapter there is a section describing the process of distinguishing fact from fiction. They specify that one must be skeptical to a certain extent in order to test something. They also include the six principles of scientific thinking. The six principles are ruling out rival hypotheses, correlation isn't causation, falsifiability, replicability, extraordinary claims require extraordinary evidence, and occam's razor. The next section goes into detail about the history of psychology. This is an interesting chapter because it does a nice job of setting you up for the rest of the book.
