  Political Science and Scientific
   Methods in Studying Politics
Political Science

An academic and research discipline that
   deals with the theory and practice of
 politics and the description and analysis
      of political systems and political
                   behavior.
Historical
Developments
• Beginnings traced
  to Ancient Greece
  • Socrates
  • Plato
  • Aristotle
• Academic Field in U.S.
  • Columbia University 1880
     • First political science department
  • American Political Science Association
     • Formed in 1903
Subfields

•   Comparative Politics
•   American Politics
•   International Relations
•   Public Policy
•   Political Research Methods
•   Political theory
•   Specialized Groups
Focus of Research

• Normative issues
  • Issues involving value
    judgments and ethics
• Empirical investigations
  • Observable and factual
• Both Normative and Empirical
Analytical
Approaches

 • Traditionalism
 • Behavioralism
 • Postbehavioralism
Traditionalism
The analysis of the formal,
 legal, and official side of
 political life.
• Try to understand politics by examining
  •   Laws
  •   Governmental offices
  •   Constitutions
  •   Other official offices associated with
      politics
Behavioralism
The empirical analysis of
  the actual behavior of
  politically involved
  individuals and groups
• Developed after WWII          Charles Merriam 1874-1953

  • Based on the works of Charles Merriam in the
    1920s
• Stresses the importance of empirical
  analysis
  • Collection of data based on observation
  • What is, rather than what should be
Postbehavioralism

  Political Science should be
    relevant, as well as
    empirically reliable
                                   David Easton

• An alternative to both traditionalism and
  behavioralism (1969)
• Information produced by political science
  has ethical implications.
Methodology

• Scientific Method
  • The collection of data
  • Analysis of data
  • Testing of assertions
• Science’s explanations are necessarily
  incomplete and tentative
  • Always subject to falsification
Steps Involved

• Formulate an hypothesis
• Operationalize concepts
• Identify independent and dependent
  variables
• Clarify measurement criteria
• Distinguish between causation and
  correlation
• Develop scientific theories
Formulating the
Hypothesis
A statement proposing a
  specific relationship
  between phenomena.
 • “Is voting in U.S. elections related to
   age?”
 • “U.S. citizens 18-24 years of age will
   vote in lower numbers than will U.S.
   citizens 45-55 years of age.”
Operationalize
Concepts
Concepts must be defined
 precisely to allow for
 empirical testing.
 • “Young people will vote less than older
   people in the U.S.”
 • “U.S. citizens 18-24 years of age will vote in
   lower numbers than will U.S. citizens 45-55
   years of age.”
Identify Variables
The phenomena linked
 together in a
 hypothesis.

• Independent variables
  • Those that affect something
  • Example: Age
• Dependent variables
  • Those that are being affected
  • Example: Voting
Clarifying
Measurement Criteria

Specifying what is taken
 as an indicator of the
 variable.

• An indicator is evidence
• How would we obtain evidence
  regarding our variable of voting?
Causation and
 Correlation
• Causation:
  • One variable absolutely causing or creating
    the other.
     • Being age 20 absolutely determines whether
       someone will vote.
• Correlation:
  • Changes in one variable appear when
    there are changes in another variable.
     • Lower voting appears with younger age groups.
Scientific Theories

• Seek to offer explanations
  about why and how correlations occur.
• Seek to predict.
• Having found a relationship between age and
  voting, the political scientist might theorize:
  • Relationship is related to different mobility patterns
    among groups.
• Most interesting aspect of science.
Francis Bacon - 1600s

• Science can free us from
  various “idols” (errors,
  misconceptions, and distorted
  views).
  •   Idols of marketplace
  •   Idols of the tribe
  •   Idols of the den
  •   Idols of the theater
Idols of the
Marketplace
• Errors based on
  misunderstanding
  and faulty
  communication.

• Errors related to our inexact use of
  language.
Idols of the Tribe

• Errors related to the
  flaws of human nature
• Errors caused by the human tendency
  to be:
  • Quick to judge
  • Superficial in our assessments
Idols of the Den

• Errors caused by our
  inability to see
  beyond our own particular surroundings
• Errors related to our near-sightedness
  and tendency to view our way of life as
  the standard for judging all others.
Idols of the
Theater
• Errors based on our
  beliefs in dogmatic
  teachings.
• Errors caused by believing in systems
  of thought characterized by inflexibility
  closed off to questioning and critical
  analysis.
Research Strategies


•   Case Studies
•   Survey Research
•   Experiments and Quasi-Experiments
•   Indirect Quantitative Analysis
Case Studies

An investigation of a
 specific phenomenon
 or entity.
• Strength:
  • Allows for in-depth study
• Weakness:
  • Information may not apply to other cases
Survey Research
Questionnaires and/or
 interviews to gather
 data.
• Strengths:
  • Large amounts of information can be gathered
    and assessed
  • Information more general than in case studies
• Weaknesses:
  • Wording, sampling, and other problems
  • Lacks up-close, in-depth details of a case study
Experiments
Investigation of a
  hypothesis by using a
  test group and a
  control group.
• Strength:
  • Experimental conditions allow researchers to
    carefully test hypotheses.
• Weaknesses:
  • Participants may alter behavior
  • Many questions cannot be tested by experiments
Quasi-Experiments

• Field experiments
• Like experiments, but
  unable to have true
  control group
Indirect Quantitative
 Analysis
The analysis of data already
  compiled by others

• Strength:
  • Researcher builds on findings of others
• Weakness:
  • Often difficult to compare findings for
    different purposes.
Limitations of
Science
• Human bias
• Human behavior is often
  unique
• How do we know
  findings are correct?
• Do we ignore important questions?
• Science in conflict with ethics?
One Nation, Underprivileged



    Rank 2: Below the Line
War on Poverty
“It will not be a short or
     easy struggle, no
     single weapon or
    strategy will suffice,
    but we shall not rest
   until that war is won.
   The richest nation on
     earth can afford to
     win it. We cannot
      afford to lose it.”    Lyndon B. Johnson
Poverty Defined

    A lack of those
  necessities that “the
 custom of the country
 renders it indecent for
   creditable people,
   even of the lowest
  order, to be without.”
                           Adam Smith
U.S. Poverty

• Age group
  most at risk is
  children

• U.S. level of poverty is one of the
  highest in the industrialized world
“It is poverty to decide that a child must
 die so that you may live as you wish.”
                 ~ Mother Teresa of Calcutta

Grigsby slides 2

  • 1. Grigsby 2 Political Science and Scientific Methods in Studying Politics
  • 2. Political Science An academic and research discipline that deals with the theory and practice of politics and the description and analysis of political systems and political behavior.
  • 3. Historical Developments • Beginnings traced to Ancient Greece • Socrates • Plato • Aristotle • Academic Field in U.S. • Columbia University 1880 • First political science department • American Political Science Association • Formed in 1903
  • 4. Subfields • Comparative Politics • American Politics • International Relations • Public Policy • Political Research Methods • Political theory • Specialized Groups
  • 5. Focus of Research • Normative issues • Issues involving value judgments and ethics • Empirical investigations • Observable and factual • Both Normative and Empirical
  • 6. Analytical Approaches • Traditionalism • Behavioralism • Postbehavioralism
  • 7. Traditionalism The analysis of the formal, legal, and official side of political life. • Try to understand politics by examining • Laws • Governmental offices • Constitutions • Other official offices associated with politics
  • 8. Behavioralism The empirical analysis of the actual behavior of politically involved individuals and groups • Developed after WWII Charles Merriam 1874-1953 • Based on the works of Charles Merriam in the 1920s • Stresses the importance of empirical analysis • Collection of data based on observation • What is, rather than what should be
  • 9. Postbehavioralism Political Science should be relevant, as well as empirically reliable David Easton • An alternative to both traditionalism and behavioralism (1969) • Information produced by political science has ethical implications.
  • 10. Methodology • Scientific Method • The collection of data • Analysis of data • Testing of assertions • Science’s explanations are necessarily incomplete and tentative • Always subject to falsification
  • 11. Steps Involved • Formulate an hypothesis • Operationalize concepts • Identify independent and dependent variables • Clarify measurement criteria • Distinguish between causation and correlation • Develop scientific theories
  • 12. Formulating the Hypothesis A statement proposing a specific relationship between phenomena. • “Is voting in U.S. elections related to age?” • “U.S. citizens 18-24 years of age will vote in lower numbers than will U.S. citizens 45-55 years of age.”
  • 13. Operationalize Concepts Concepts must be defined precisely to allow for empirical testing. • “Young people will vote less than older people in the U.S.” • “U.S. citizens 18-24 years of age will vote in lower numbers than will U.S. citizens 45-55 years of age.”
  • 14. Identify Variables The phenomena linked together in a hypothesis. • Independent variables • Those that affect something • Example: Age • Dependent variables • Those that are being affected • Example: Voting
  • 15. Clarifying Measurement Criteria Specifying what is taken as an indicator of the variable. • An indicator is evidence • How would we obtain evidence regarding our variable of voting?
  • 16. Causation and Correlation • Causation: • One variable absolutely causing or creating the other. • Being age 20 absolutely determines whether someone will vote. • Correlation: • Changes in one variable appear when there are changes in another variable. • Lower voting appears with younger age groups.
  • 17. Scientific Theories • Seek to offer explanations about why and how correlations occur. • Seek to predict. • Having found a relationship between age and voting, the political scientist might theorize: • Relationship is related to different mobility patterns among groups. • Most interesting aspect of science.
  • 18. Francis Bacon - 1600s • Science can free us from various “idols” (errors, misconceptions, and distorted views). • Idols of marketplace • Idols of the tribe • Idols of the den • Idols of the theater
  • 19. Idols of the Marketplace • Errors based on misunderstanding and faulty communication. • Errors related to our inexact use of language.
  • 20. Idols of the Tribe • Errors related to the flaws of human nature • Errors caused by the human tendency to be: • Quick to judge • Superficial in our assessments
  • 21. Idols of the Den • Errors caused by our inability to see beyond our own particular surroundings • Errors related to our near-sightedness and tendency to view our way of life as the standard for judging all others.
  • 22. Idols of the Theater • Errors based on our beliefs in dogmatic teachings. • Errors caused by believing in systems of thought characterized by inflexibility closed off to questioning and critical analysis.
  • 23. Research Strategies • Case Studies • Survey Research • Experiments and Quasi-Experiments • Indirect Quantitative Analysis
  • 24. Case Studies An investigation of a specific phenomenon or entity. • Strength: • Allows for in-depth study • Weakness: • Information may not apply to other cases
  • 25. Survey Research Questionnaires and/or interviews to gather data. • Strengths: • Large amounts of information can be gathered and assessed • Information more general than in case studies • Weaknesses: • Wording, sampling, and other problems • Lacks up-close, in-depth details of a case study
  • 26. Experiments Investigation of a hypothesis by using a test group and a control group. • Strength: • Experimental conditions allow researchers to carefully test hypotheses. • Weaknesses: • Participants may alter behavior • Many questions cannot be tested by experiments
  • 27. Quasi-Experiments • Field experiments • Like experiments, but unable to have true control group
  • 28. Indirect Quantitative Analysis The analysis of data already compiled by others • Strength: • Researcher builds on findings of others • Weakness: • Often difficult to compare findings for different purposes.
  • 29. Limitations of Science • Human bias • Human behavior is often unique • How do we know findings are correct? • Do we ignore important questions? • Science in conflict with ethics?
  • 30. One Nation, Underprivileged Rank 2: Below the Line
  • 31.
  • 32. War on Poverty “It will not be a short or easy struggle, no single weapon or strategy will suffice, but we shall not rest until that war is won. The richest nation on earth can afford to win it. We cannot afford to lose it.” Lyndon B. Johnson
  • 33. Poverty Defined A lack of those necessities that “the custom of the country renders it indecent for creditable people, even of the lowest order, to be without.” Adam Smith
  • 34. U.S. Poverty • Age group most at risk is children • U.S. level of poverty is one of the highest in the industrialized world
  • 35. “It is poverty to decide that a child must die so that you may live as you wish.” ~ Mother Teresa of Calcutta
