Midterm Exam Flashcards
Popper salient features
- scientists are problem solvers
- it is science if it can be falsified
- knowledge by accumulation
- can never say a hypothesis is true~can only gain or lose confidence in a hypothesis
- positivism
positivism (Popper)
- we can use logic and senses to increase knowledge
- findings must be able to be replicated
Theory survival (Popper)
if a theory survives for a long time w/o being falsified, then it means it is the best available until it is falsified
Kuhn salient features
- must at look at history
- paradigms
- revolutionary science
- new science incommensurable
Paradigms (Kuhn)
- scientists are within a culture
- questions, methods at a given time
- work within boundaries
- what is acceptable science and what is not
revolutionary science (Kuhn)
-creates a crisis in normal science to become the new way of thinking the “new” normal science
incommensurability (Kuhn)
- each paradigm is the new normal science
- can’t compare with the old normal science
- not related at all
- scientific knowledge does not build on itself
- can’t understand one from within another
checklist for a good theory
- parsimony
- causations
- commensurability
- objectivity
- prediction
- eliminate rival hypotheses
- grandmother test
parsimony
- simplicity
- fewer variables than hugely complex explanations
- explanatory power
causations
- must be able to be diagramed
- IV and DV
commensurability
-clear definitions and measures (explicitly stated)
objectivity
- no subjectivity
- use methods that eliminate the possibility of biases
- avoid case selection bias
prediction
-better theories allow to predict events
eliminate rival hypotheses
-show how rivals can’t explain the thing that I’m explaining
grandmother test
- make it interesting w/not too obvious answers
- applicable to the big picture and applicable to broader groups
