Please give examples showing how deduction is related to social science research.

Ideally, deduction is the basis of research in the social
sciences.  Deduction is the process of taking a theory and testing hypotheses based on
that theory.

There are many examples of how deduction can
be used in social science research.  Here are two
examples:

• In the field of International
  Relations, there is a theory that says that democracies are inherently more peaceful
  than other types of governments.  One can deduce from that theory that democracies would
  be less likely to fight with one another.  Researchers have, based on that theory,
  looked at all the wars in recent history to try to evaluate that
  hypothesis.


• In the field of economics, there is a theory
  that minimum wage laws are bad for less-skilled workers.  From that comes a hypothesis
  that an increase in the level of the minimum wage would lead to a decrease in employment
  among those types of workers.  Economists have done research to evaluate that hypothesis
  by looking at employment in states before and after they raise their minimum
  wages.
