Reading 2: ch.2&3 (philosophy of social science) Flashcards
positivism
- movement to establish a sound basis for social scientific inquiry = 1950s and 1960s (behavioural revolution)
- maintains that researchers can arrive at factual, reliable and objective answers to questions about the social world by employing the methods used in the natural sciences
- claims (just like scientific realism) that the social world is no different than the natural world
(positive political theory)
assumes that rational self-interest motivates behavior
NOT attitudes
behavioral revolution changed the field:
- new discussions and debate about desirability and possibility of using scientific methods to attain reliable, empirical, causal knowledge
- broadening the domain of political research (by drawing on theories from other disciplines)
- emphasis on research based on empirical observation (falsifiable)
- importance of replication
classical positivism
- tenets
- about causality
4 basic tenets:
- naturalism (no difference social and natural sciences/world)
- empiricism (what we know of the world is limited to that what we can see)
- goal of social science is to explain and predict by means of laws, which can be established based on induction
- it is possible to distinguish between facts and values + to obtain value-free knowledge
causality conceptualization of Hume (causality constituted by empirical regularities among observable variables, this leads to a psychological expectation of causality, but we cannot see it therefore not know it) -> seeks empirical regularities rather than to discover causal mechanisms
logical positivism
- early 20th century as movement within philosophy
contributes to positivist thought:
- wants to combine induction (empiricism) and deduction (logic): argues that logical reasoning and mathematics should also be treated as sources of knowledge in addition to empiricism
- establishes verification as criterion for establishing truth claims + science (rather than metaphysics)
*some argue that its greatest contribution to positivism is that it inspired critique from Popper
deduction vs induction
+ retroduction
induction = particular observations/cases -> generalizations
- observation -> pattern - tentative hypothesis -> theory
deduction = broad generalizations/theories -> specific observations and meanings/implications
- theory -> hypothesis -> observation -> confirmation
in practice research is often retroduction: interaction of induction and deduction in an evolving, dynamic process of discovery and hypothesis formation
Popper
against (logical positivist) principle of verification: we cannot deductively establish general statements of scientific knowledge
- induction is bad: no matter how many observations confirm a theory, only one observation is necessary to falsify it
we shouldn’t try to verify a hypothesis, we should try to falsify it
falsification = demarcation science and pseudo-science/metaphysics
science/theory doesn’t start with observation, observation is used to test and falsify theory
criticism to Popper
- he distinguishes between fact and theory (he claims that our observations/facts can be established independently of the theory that they mean to test)
- Popper’s notion of falsifiability is at odds with how scientists work in practice (they don’t really seek to falsify their theories)
classical positivism vs logical positivism vs Popper’s critique
classical positivism: science through induction
logical positivism: induction + deduction can be used to discover laws
Popper: only deduction to establish laws of social life as a basis for explanation
deductive-nomological model
Hempel
something is explained when it is shown to be a member of a more general class of things, when it is deduced from a law or a set of laws
when is something a law rather than it appears to be a law but is accidental?
law expresses a necessary connection between properties, accidental generalization doesn’t + laws can be tested based on their predictions
we confirm that a generalization is a law by treating it as a hypothesis (hypothetico-deductive model)
hypothetico-deductive model
Hempel
according to this model we confirm that a generalization is a law by treating it as a hypothesis, testing the hypothesis by deducing it from predictions of further phenomena that should be observable as a consequence of the hypothesis
*we look at multiple hypotheses to see which has the most explanatory value (look which hypothesis makes the most accurate predictions)
scientific realism
- naturalist ontology (social world and natural world are the same) = same as positivism
- what is objectively real is not just observable elements, also unobservable elements (we can see its effects) = breaks with positivism
- explanation can be based on observable regularity AND unobservable causal mechanisms that link cause and effect
- ## scientific goal = describe and explain observable and nonobservable aspects of the world
conception of causality = observable regularities + unobservable causal mechanisms that generate the regularities
Charles Tilly - 3 causal mechanisms in the social world
*mentioned with scientific realism
- environmental (external influences on conditions effecting social life)
- cognitive (operates through alterations of individual and collective perception)
- relational (alter connections among people, groups and interpersonal networks)
debate about the scientific status of unobservable entities
- 3 main questions
- What is the ontological status of macro-social mechanisms used to explain social outcomes? = What are the basic entities that make up the social world?
- (methodological) individualism (social phenomena are made up of combined results of individual action)
- (methodological) holism (social facts have social causes that are irreducible to facts about individuals: the whole is not directly explicable in term of its parts) - How do we explain macro-social phenomena?
- methodological individualism vs methodological holism (problem = reification -> not enough focus on agency) vs ‘micro-foundations (combination individualism and holism: intentional states that motivate individual action) - How do macro-social ‘social mechanisms’ produce social outcomes? Providing explanations of macro-social phenomena with micro-foundations
- James Coleman: diagram (Coleman’s Bathtub/boat): causal relations flow downwards from macro phenomena (e.g. institutions) shape the conditions of individual actions + conditions give rise to individual actions + individual actions aggregate up to macro outcomes
- he argues for a combination of micro-macro linkages (see p. 45)
reification
tendency to treat macro-social structural entities as if they had a concrete, material existence; to treat them as analytically indepe3ndent of their constituent elements; inert, unchanging and unmediated by human agency
*problem with methodological holism
e.g. globalization as result of capitalism and market thinking
