PSYA02 Jan. 11, 2013 Free Will and Rationality We often feel as though the choices we make in life are rationale … the result of mental calculations related to the costs and benefits of performing certain actions.  Realization that we are not machines and are therefore capable of controlling our own behaviours (maybe?) The notion that we make choices by maximizing benefits and minimizing costs is called Rational Choice Theory. Ties to ethics/religion/law: believe that some choices are “wrong” and punish those who make them … assuming they made a rational choice  Religion: based on the idea of rational choices. By following the teachings (dogma) of the church, people should be able to make better choices.  Law: this is especially prevalent in criminal trials. It is always a task to prove that the criminal had consciously made the decision to commit the crime. (Premeditation = murder 1; random act = murder 2) o Example: Colorado shooter – did he actually have the conscious thought to commit the crime? The fact that his apartment was booby trapped to distract that police force shows planning = premeditation = rational thought. o Some opinions argue that we don‟t actually make decisions.

As a student she was deeply concerned with issues of discrimination and social justice, and she participated in anti-nuclear demonstrations. Which of the following is more likely (a) Linda is a bank teller, or (b) Linda is a bank teller and a feminist The answer is a however most people will pick b based on stereotypes. None of the info except for the fact that Linda is a bank teller is really relevant. Sometimes stereotypes can be good (glasses make you look smarter) but for the most part, they are inaccurate and end up with people being filed into inaccurate groups, leading to conjunction problems (when it is assumed that specific conditions are more probable than a single gener
