Ch 10 Flashcards
Ad hoc hypothesis
A hypothesis, or theory, that cannot be verified independently of the phenomenon it’s supposed to explain. Ad hoc hypotheses always make a theory less simple—and therefore less credible.
Conservatism
A criterion of adequacy for judging the worth of theories. A conservative theory is one that fits with our established beliefs.
Criteria of adequacy
The standards used to judge the worth of explanatory theories. They include testability, fruitfulness, scope, simplicity, and conservatism.
Fruitful
A criterion of adequacy for judging the worth of theories. A fruitful theory is one that makes novel predictions.
Inference to the best explanation
A form of inductive reasoning in which we reason from premises about a state of affairs to an explanation for that state of affairs:
Phenomenon Q.
E provides the best explanation for Q.
Therefore, it is probable that E is true.
Scope
A criterion of adequacy for judging the worth of theories.
A theory with scope is one that explains or predicts phenomena other than that which it was introduced to explain.
Simplicity
A criterion of adequacy for judging the worth of theories. A simple theory is one that makes minimal assumptions.
Testable
A criterion of adequacy for judging the worth of theories.
A testable theory is one in which there is some way to determine whether the theory is true or false—that is, it predicts something other than what it was introduced to explain.
TEST formula:
A four-step procedure for evaluating the worth of a theory:
Step 1.State the Theory and check for consistency.
Step 2. Assess the Evidence for the theory.
Step 3. Scrutinize alternative theories.
Step 4. Test the theories with the criteria of adequacy.
What is cogency?
When the premise of an argument is true
What is the requirement of consistency
Internal and external consistency
Internal = no contradictions
External = not going against the relèvent evidence
cognitive dissonance is…
When reality conflicts with what we believe
Type of explanations
1.procedural - how something is done
2.interperetive - what is the meaning
3.functional - how it functions
4.Theoretical- explanations that use a theory to explain a case -then applying it to a case at hand. ( the only one that is a clam)
