decision heuristics and mechanisms Flashcards
decision heuristics
Applying simple rules to simplify decisions, used most of the time under (1) uncertainty or when we (2) have incomplete information (“should I bring an umbrella? will it rain?”)
Why is it not always a good idea to use decision heuristics?
Can be subjective and biassed
Sunk cost fallacy
Resources that we’ve already invested into something tend to influence our decisions to stick with something even if these decisions do not increase the likelihood of a positive outcome
Expected Utility theory (rational decision making)
people make decisions that maximize utility (happiness, health, money) given available information
risk aversion
tendency to avoid risk (would be more disturbing to lose $100 than to win $100 - causes people to decline bets in fear of loss)
risk aversion is dependent on ____
framing (either gain or loss)
When things are framed as gains then ____
People avoid uncertainty (risk aversion)
When things are framed as losses then ____
People seek uncertainty (risk taking)
framing effect
When a choice is framed as a gain (saving lives), people employ a risk aversion strategy, when a choice is framed as a loss (losing lives), then people are more likely to take risks
Endowment effect
Over-valuation of current possessions given by ownership (as soon as we have something, the value increases) - if an individual goes on a test drive with a new car, he or she is more likely to buy it due to the emotional attachment to it.
What is one explanation for loss aversion?
Asymmetry in emotional prediction - when making a prediction, people often don’t take into account the coping mechanisms used to deal with adversity – people will rationalize their failures (“the salary wasn’t what I wanted anyways”)
What pros and cons of heuristics
Pro = saves time
con = increases bias
Hindsight bias
the tendency to overestimate our ability to have foreseen an outcome (“I knew it all along”)
What are some limitations of the hindsight bias?
- people tend to take too much risk (become overconfident in their abilities)
- makes it hard to appreciate uncertainty
Myside bias
When people evaluate evidence in a way that is biased to their own opinions (Type of confirmation bias)
