FINAL EXAM Flashcards
Adam Smith, father of modern economics. What were the assumptions of modern economics model of CB?
- Internal knowledge (preferences)
- External knowledge (market and choices)
- Choose rationally to maximize utility
homo economicus
Consumers are rational, selfish, consistent and looking for optimal
Principle of Bounded rationality (H. Simon)
The idea that we make choices with limited rationality:
- limited info
- cognitive limitations
- time
- risk
- emotional involvement
Satisficing
Satisfy + Suffice
Accepting choices that are good enough but could be optimized
Prospect Theory (Amos Tversky & Daniel Kahneman)
95% of non conscious brain activity
- People make economic choices based on subjective value and heuristics
- Reference points matter: changes on wealth
- Risk averse with gains and risk seeking with loses
Instincts
Innate and unalterable patterns of activity given biological species
Habits (45% of everyday behaviors)
automatic and rigid patterns of behavior learned by effort and repetition
transform automatic, decrease mental activity effort and energy expense
they become an itch we need to scratch
Stroop effect
word association influenced by color
phenomenon that occurs when you must say the color of a word but not the name of the word.
Cognitive illusions
Situations where your mind systematically and unconsciously misperceives or misinterprets the info available (like optical illusion)
dunning-kruger
illusion of superiority, incorrectly perceive as to even if they have lower competence
biases
systematic (non-random) and non conscious patterns of deviation from norm logic or rationality
fluency bias
fluent statements are better remembered
- more true
- more likeable
- more famous
- more intelligent
ambiguity bias
avoid ambiguity and uncertainty preferring the known of a favorable outcome
heuristics
cognitive shortcuts to simplify decisions, substitute a difficult question with an easier one (tennis)
The doer
system 1, immediate experience, impulsive, impatioent
The planner
system 2, maximize utility rational patient
Procastination
When we Put off for tomorrow what we can do now
Planning fallacy
overestimate the ability and underestimate the time and resources to complete a project
(i.e. oxford dictionary)
Experiencing self (emotional self)
NOW, present at the moment
Unconscious
Remembering self (rational self)
Conscious
PAST
storyteller not so accurate
Guides decisions
We tend to make rational decisions to satisfy our remembering self and avoid regret
true
Remembering self governed by 2 rules…
- Duration neglect rule: insensitive to duration
2. Peak end rule: judge by the most intense peak and its end rather than the whole experience (i.e. colonoscopy)
Example of Phineas Gage
We need both rational and emotional selves to properly function and be able to make decisions
affect heuristic (intuition)
Automatic mental shortcut to make quick judgments by using emotional response
Conflict of selves: cognitive dissonance
mental discomfort experience when holding 2 or more contradictory ideas, actions don’t match beliefs
hot-cold empathy gap
cognitive bias mispredicting own behavior and preferences across affective states
Why system 1 exists?
- Brain evolution has created ways to avoid energy expense
- maintains energy, doesn’t deplete brain power
- allows for a smaller head
brain fatigue
brain gets depleted and becomes less effective
Brain fatigue examples
angry at colleagues and families, splurge on clothes, buy junk food and can’t resist the seller’s offer to upgrade his phone.
status quo bias
when low on energy or facing difficulties we tend to avoid change and maintain current state
(example israeli parole board, organ donation)
Willpower
depletes and leads to self control impairment (i.e. impulse purchases)
The habit loop
- Trigger
- Routine
- Reward
Triggers
cue to reminder a routine (internal, memory / external)
- location
- time
- emotions
- other people
- immediately action
Reward
something positive or avoid something negative. The closer to the routine the better
Nucleus accumbens
Activated when we crave something
Repeated coactivation
forges direct links in memory between triggers and responses (associative learning)
how do we create habits
- associate the new routine with an existing trigger and a reward (new or not) and repeat until automatic
- Keep trigger and reward but insert new routine.
implementation intentions (P. Gollwitzer)
self regulatory strategy “if-then plan” that helps in habit creation
Specifies when, where and how of a goal oriented behavior
keystone habits
habits that have power to create a chain reaction of change
When consumer tend more to follow habits?
- under time pressure
- when distracted
- when self control resources are depleted
habit research
- in context research
- habits & practices studies
in context research
people are interviewed or observed while performing the task
habits & practices studies
large-scale studies where respondents are asked to keep written records of usage or shopping habits for long periods
choices
act or instance of selecting among options
they involve comparison and a cost
Paradox of Choice
(jam experiment)
too many options make decisions difficult, can lead to no decision, can decrease satisfaction and increase regret
rational choice theory
expected value, the probability weighted average of a mathematical outcome
expected utility theory (D. Bernoulli)
subjective value, the utility each person assigns to an otucome
3 principles of prospect theory
- loss aversion
- reference dependence (framing)
- diminishing sensitivity
Prospect theory: Loss aversion
- losses cause greater emotional impact.
- more motivation to avoid loss than to acquire gain
Prospect theory: Loss aversion implications
- non consistent risk preferences
- possibility and certainty effect
- status quo bias
- endowment effect
Loss aversion implications: non consistent risk preferences
we are risk averse in gains and risk seeking in losses (pay of premium to remove risk)
