Biases and paternalism/libertarianism Flashcards
cognitive biases
psychological traits, selected by evolution to face other situations than logical reasoning. The automatic tendency to privilege some forms of information with respect to other
Deficits
a complete and extended inability to perform a cognitive function
Irrationality thesis
the view that humans have an underlying ability to reason characterized by principles that diverge from the normative principles of reason
Modus Ponens
Fallacy of affirming the consequent
If Darwin wrote Hamlet, then Darwin was a great writer.
Darwin was a great writer
Therefore Darwin wrote Hamlet
Modus tollens
Fallacy of denying the antecedent
If you are a ski instructor, then you have a job.
You are not a ski instructor.
You do not have a job
Jean Piaget’s model
1932
maturity is obtained along with the capacity of formal operations (logic)
PROVEN FALSE:
humans can’t perform modus tollens and similar inferences naturally
Lawrence Kohlberg
1958
stages of moral development based on piaget’s model
Framing effect
decisions are influenced by the way in which the problem is described
contradicts condition of consistency
Basic conjunction experiment
Linda (bank teller or bank teller and feminist)
probability of 2 events occurring simultaneously is less than (or equal to) one of them
Representativeness heuristic
judging a situation based on how similar the prospects are to the prototypes the person holds in their mind (linda)
Base rate neglect
People tend to neglect the base rate probability
Instead of taking into account the base rate or prior probability of an event, people are often distracted by less relevant information.
(engineers and lawyers)
Anchoring heuristic
human tendency to accept and rely on the first piece of information received before making a decision
Availability heuristic
mental shortcut that relies on immediate examples that come to a person’s mind when evaluating a specific topic
(for example, assessing risk of heart attack based on such occurrences among one’s acquaintances)
Confirmation bias
selectively focusing on evidence supporting one’s beliefs
Homophily
people endorsing certain beliefs tend to befriend one another
Compatibility bias
positive dimensions weighted more heavily in choosing than in rejecting, and negative dimensions weighted more heavily in rejecting than choosing
(ice cream parlor, choosing flavour and deciding which ones to give up)
Type 1 error
False positive
incorrectly rejecting the null hypothesis
believing in something false
Type 2 error
False negative
Accepting the null hypothesis that is false
Not believing in something that is correct
Dual process theory
Based on system 1 and system 2
Kahneman is one of the defenders
System 1 is automatic and fast
system 2 is more nuanced and slow
Three process models
Reflective, algorithmic, and autonomous mind
–> reflective and algorithmic type 2
Hybrid model: implicit knowledge, explicit knowledge retrieval, processing (takes both into account)
Fearing dead risk
cognitive bias that makes people focus on consequences of an event (while neglecting its likelihood)
Debiasing approaches
-Education and training (cognitive)
-Incentives (reward; emotional)
-Nudging (situational, libertarian paternalism)
SIC syndrome
The concept that doctors act in Self-Defense, Innumeracy and Conflicts of interest
Science Comprehension Thesis (SCT)
Public conflict arises from a lack of understanding or reasoning capacity.
Identifies defects in the public’s knowledge and reasoning capacities
Identity-protective Cognition Thesis (ICT)
Cultural and political conflicts shape individual’s interpretation of evidence to align with group identities
i.e. the tendency of individuals to unconsciously dismiss evidence that does not reflect the beliefs that predominate in their group
Nudging
proposed by Thaler and Sunstein, advocates designing choice environments (or nudges) that guide individuals toward better decisions without limiting freedom
Gerd Gigrenzer article
against nudging, against assumptions
1. people lack rationality
2. people are hardly educatable
3. choice architects are assumed to be benevolent philosopher-kings while they may pursue conflicting interests
