WEEK 13: Judgment, Reasoning, and Decisions Flashcards
Bottom-up reasoning.
INDUCTIVE REASONING
Top-down Reasoning
DEDUCTIVE REASONING
Reasoning that begins from specific observations to broader generalizations and theories. Conclusions are probability, but not definite.
INDUCTIVE REASONING
Reasoning that begins from more general to the more specific.
DEDUCTIVE REASONING
Deductive Reasoning determines whether a conclusion logically follows from statements called ________.
Premises
STRENGTH OF INDUCTIVE ARGUMENT
How we do the observations about a particular category, representing all the members of that category.
Representativeness of Observation
STRENGTH OF INDUCTIVE ARGUMENT
The conclusion is very strong because of a number of these.
Number of Observations
STRENGTH OF INDUCTIVE ARGUMENT
Stronger evidence results in stronger conclusions.
Quality of Evidence
POTENTIAL SOURCES OF ERRORS IN JUDGEMENTS
Rules of thumb that are likely to provide the correct answer to a problem but are not foolproof.
Heuristic
POTENTIAL SOURCES OF ERRORS IN JUDGEMENTS
Events that are more easily remembered are judged as being more probable than events that are less easily remembered.
Availability Heuristic
POTENTIAL SOURCES OF ERRORS IN JUDGEMENTS
Probability that A is a member of class B is determined by how well properties of A resemble properties usually associated with B.
Representativeness Heuristic
POTENTIAL SOURCES OF ERRORS IN JUDGEMENTS
Strong correlation between two events appears to exist, but doesn’t.
Illusory Correlation
POTENTIAL SOURCES OF ERRORS IN JUDGEMENTS
Relative proportions of different classes in the population.
Base Rate
POTENTIAL SOURCES OF ERRORS IN JUDGEMENTS
Probability of conjunction of two events (A and B) cannot be higher than the probability of single constituents.
Conjunction Rule
POTENTIAL SOURCES OF ERRORS IN JUDGEMENTS
Tendency for people to generate and evaluate evidence and test their hypothesis in a way that is biased toward their own opinions and attitude.
This is a type of conformation bias
Myside Bias
POTENTIAL SOURCES OF ERRORS IN JUDGEMENTS
Selectively looking for information that conforms to a hypothesis and overlooking information that argues against it.
Confirmation Bias
POTENTIAL SOURCES OF ERRORS IN JUDGEMENTS
The larger the number of individuals drawn from a population, the more representative the group will be of the entire population.
Law of Large Numbers
ERRORS IN JUDGEMENTS
Error: Easily remembered event is less probable
Availability Heuristic
ERRORS IN JUDGEMENTS
Error: There is no correlation, or it is weaker than it appears to be.
Illusory Correlation
ERRORS IN JUDGEMENTS
Error: Presence of similar properties doesn’t predict membership in Class B.
Representativeness Heuristic
ERRORS IN JUDGEMENTS
Error: Base rate information is not taken into account
Base Rate
ERRORS IN JUDGEMENTS
Error: Higher probability is assigned to the conjunction.
Conjunction Rule
ERRORS IN JUDGEMENTS
Error: It is assumed that a small number of individuals accurately represent the entire population.
Law of Large Numbers
ERRORS IN JUDGEMENTS
Error: People let their own opinions and attitudes influence how they evaluate evidence needed to make decisions.
Myside Bias
