The comparative method

  1. The Phenomenon: what is the object of study?
  2. Outcome: define the outcome and determine the binary conditions (i.e. what constitute presence/absence)
  3. The degree of analysis (which is flexible)
    • How many cases?
    • How many variables?
  4. What are the theories we wish to test?
  5. Determine the key variables as mentioned by those theories (as well as their binary conditions)
  6. Collect data on cases and create the truth table
    • Outcome
    • Variables
  7. Reduce and perform Boolean analysis
  8. Factoring, if required
  9. Edit, revise, edit, revise, etc
