Chapter 13: Judgement, Decisions, and Reasoning
• Decisions can depend on how choices are presented:
o People’s judgets are affeted y the way hoies are stated
o Think about the example of people saying they would be an organ donor but
very few actually taking action and going through the opt-in procedure
▪ Different from an opt-out procedure
o Status Quo Bias:
▪ tendency to do nothing when faced with making a decision
• think about the example of default offerings of cheaper or more
expensive driving insurance plans
o Way a choice is presented is important when a person is forced to pick one
alternative or another
▪ think about experiment that frames the disease problem in two different
ways
▪ Risk Aversion Strategy:
• idea of saving 200 lives with certainty is more attractive than the

▪ Risk Taking Strategy:
• certain death of 400 people is less acceptable than taking a 2 in 3
risk that 600 people will die
