Introduction
Political science at the end of WWII:
● Thick descriptions.
● Normative component = many judgements about how it worked & the way the world should
work → Marxism, Liberalism, Capitalism.
● Political science = descriptive & judgmental > analytical.
How could we evaluate the merits of these claims?
● Judgments & speculation = subjective.
● Could we move toward a more objective approach?
○ Research’s subjectivity & objectivity = continuum (fuzzy theory).
○ NO pure objective social science research, BUT some prefer to minimise subjective
factors’ influence by scientific & standardised approaches + peer review process.
● Vienna Circle’s (20th century): Group of philosophers/scientists that promoted the idea of
“logical positivism/empiricism” = only prepositions verified through direct
observation/logical proof have meaning.
➔ Economists among the first groups who:
◆ Internalised & started applying logical positivism in social sciences =
impacted scientific research in different fields.
◆ Applied RCT to modern social issues.
Criticisms of RCT:
● Green & Shapiro = discrepancy between practitioners’ faith in RCT & its failure to deliver
empirically, warrants a closer inspection of RCT as a scientific enterprise.
● Perestroika Movement = dismantling of the Orwellian system in APSA.
Responses to criticisms: → problems with these arguments:
● Fiorina = how could political science have ● Empiricism ≠ RCT ≠ formal
prospered otherwise? (mathematical) modelling.
● Behavioural economics is offered to
● Shepsle = do NOT let go of something until
complement RCT.
you have something else to hold on to.
Tributes:
● Hume = Scottish philosopher in the Enlightenment who discussed utilitarianism & logical positivism.
● Ibn Khaldun = Tunisian philosopher & social scientist (process tracing), arguing good governance &
offering ethnographical analysis.
● Wittgenstein = Austrian philosopher → “nothing is so difficult as not deceiving oneself.”
