Lecture 5 Flashcards
What are the choices we have in developing a new theory?
- We can choose to falsify the theory
- We can choose to disregard the observation contradicting the new theory
What is a pragmatic choice?
This is a solution to resolve conflict between theory and observation that is based on pragmatic considerations
What are quine’s premises?
- There is no fundamental difference between synthetic and analytical statements (we can only test a whole system of sentences)
- Every sentence within a system of knowledge can be given up to solve conflict between theory and observation.
What are Duhem’s premises?
- Every hypothesis requires assumptions
- Question: is it the hypothesis that is falsified or the assumptions underlying it
- Conclusion: Never test a single hypothesis but a whole system of hypotheses that constitute a theoretical framework
What is punctuated equilibrium?
For most periods of time species don’t change much, in certain periods there is an event that speeds up the development of species substantially.
Name the four theories of truth?
- Correspondence theory of truth: truth of synthetic statements depends on correspondence to reality
- Coherence theory of truth: truth analytical statements depends on coherency to what we already know
- Consensus theory of truth: collectively agreed upon
- Pragmatic theory of truth: depends on pragmatic considerations
What are meta-theories?
These are theories about theories, based on ontological and epistemological assumptions
What are the ontological assumptions underlying metatheories?
These are questions about what the basic unit of analysis is. This can be viewed individualistic or holistic
What is rational choice theory?
Rational individuals make decisions maximizing their satisfaction. This explains choices on an indvidiual level.
What is an explanatory model?
This is a model explaining behaviour and social level outcomes based on the rational choices of individual agents..
What are the assumptions of rational choice theory?
- Agents are fully self-interested
- Agents are perfectly rational
- Explanations should start from methodological individualism
What are the assumptions of rationality?
- Agents have complete and consistent preference ordering
- Agents have all available information
- Agents are capable of perfectly analyzing this information and calculate the maximal outcome
What is the endowment effect?
This is the effect that we value things more when we own them. This is based on loss aversion and a status quo bias
What is loss aversion?
The feeling that we experience a loss of something twice as much as a gain of the same strength.
What is the status quo bias?
This is the tendency to be more comfortable staying with the current status quo instead of deviating from it.
