Politics uses the methods of rhetoric and
advocacy to persuade people to adopt a certain
point of view.
Political science uses the scientific method to
uncover the true state of the world.
Analogy from a courtroom: lawyers versus the
jury.
Why do we call it political
science ?

Normative versus non-normative (or positive)
concerns.
Positive: The way the world is.
Normative: The way the world should be.
Rhetoric and advocacy versus the scientific
method.
Differences in Subject and Method

The Scientific Method
Form a hypothesis : a specific prediction that (1)
specifies a causal mechanism and (2) can be
empirically verified.
Gather data.
Test the hypothesis.
Reject or fail to reject the hypothesis.

“[T]he field of science is unlimited;
its material is endless; every group
of natural phenomena, every phase
of social life, every stage of past or
present development is material for
science. The unity of all science
consists alone in its method, not in
its material.”
-Pearson, 1892

Characteristics of
Scientific Knowledge
Empirical : Based on observable data.
Replicable : If I tell you how I collected my data
and how I tested it, you should be able to get the
same result as me.
Explanatory : Tells us about the state of the
world or how things work.
Probabilistic : Tells us how strong the evidence is,
never 100% certain.

Our Goal is Inference
Inference is the process of using facts we do
know to learn facts we didn’t know before.
Descriptive inference is using these facts to learn
something about the state of the world.
Causal inference is using these facts to learn
something about how the world works.
Our focus will be on causal inference.

For example …
Why did we see revolution in some Middle Eastern countries and not others?
How could we examine this question scientifically?
What would you need to observe to know if your hypothesis is correct?
That is, what are the observable implications of your hypothesis? How would this information help you rule out competing explanations?
