Chapter one introduces you to psychology and scientific thinking. Most people come into psychology thinking they already know a lot about the subject, but when taking the knowledge test most get it wrong. One subject that stuck out in this subject was pareidolia, which means siding meaningful images in meaningless visual stimuli. In 1976, the Mars Viking Orbiter took a snapshot of Mars. The image displayed a face on the surface of Mars. This lead to many thinking that there were actually Martians living on Mars. But in a later study in 2001, the Mars Global Surveyor confirmed that it was just rocks and the angle of the shot that gave the visual of a Martians face.
