The process of using the facts we know, to learn about the facts we don't know
Quantitative research
Measures average effects across many cases, like how economic growth (IV) affects democracy (DV), to see if they are correlated and reach an inference
Quantitative research
Sees the big picture, but doesn't tell a lot about why X (economic growth) affects Y (democracy)
Offers causal analysis and explanation, but may or may not apply to individual cases
Qualitative research
Focuses on one case or group of cases, to explain a group/type of cases and each individual case within the group/type
Aims to create meaning and establish power relationships, often in the positivist, interpretative or critical areas
Inference
The process of moving from the observed to the non-observed, to explain the non-observed
Quantitative research inference
If X is on average associated with Y, then X (likely) matters for Y
Qualitative cross-case comparison inference
1. If two very different cases have the same outcome Y, the similarities in X should matter to explain Y
2. If two very similar cases have different Y, then differences in X should matter for Y
Qualitative within-case analysis inference
If what we see in a case matches what we should see if explanation A was right and does not match what we should see if explanation B was right, then A is the best explanation
Research questions
Why did social revolutions occur in cases as dissimilar as 18th-century France, interwar Russia, and post-World II China?
Why did democratic regional governments fail in some places in Italy and succeeded in other places?
Qualitative research questions
Some questions might be better suited for Qualitative research
Some dimensions of the same question might be better suited for Qualitative research
Some wordings are more in tune with Qualitative research
Research puzzle
A research question that defies common sense or theoretical exceptions, restudy of what people think or do vs. Establishment studies, common sense
Research puzzles
Buying low and selling high vs. Giving away accumulative goods
Obeying rules of rebels vs. Organising nonviolent resistance
Why are engineering students overrepresented in suicide mission?
Why victims of violence vote against pro-peace candidates?
Steps to develop a research puzzle
1. Step 1: Why Y? (Puzzling outcome)
2. Step 2: Why not Y? Why not expect Y? (Established theory)
3. Step 3: Why Y despite X? (Debunk the myth)
Quantitative research can be descriptive, and Qualitative research can be explanatory
Quantitative research deals with the effects of causes, while Qualitative research deals with the causes of effects
Different logics of inference and explanation guide Qualitative and Quantitative research, but neither is superior, they are just different
Qualitative and Quantitative techniques are more or less appropriate for different research questions and goals
Different logics of inference & explanation guide Qual & Quant research
No logic is superior, just different
Quant & Qual techniques are +/− appropriate for different research questions/goals
Not to drive the wedge between quant & qual, but to facilitate communication and cooperation
People are risking to mobilise, usually the people that mobilise are not the poorest — because they have too much to loose compered to richest people
Difference in outcomes, despite convergences in initial Conditions between the cases
Cross case comparison
Explain divergences in Outcomes, despite convergences in initial Conditions
Explain convergences in O, despite divergences in initial Conditions
Identify a set of necessary & sufficient conditions for an outcome, like QCA
Probe wether the same path leads to the same outcomes across different cases
Identify different paths that lead to the same outcome — equifinality, all the paths lead to the same effects
Common types of comparison
Comparison across units
Comparison over time
Comparison across ≠ functional issue areas
Threats to good comparison
Comparison that lack structures and focus
Having too many moving parts or the wrong parts moving
Controlled comparison
1. Most similar design
2. Least similar design
Advantage of controlled comparison: help rule out alternatives explanations
Critique to comparative research
Interaction of the variables
Focusing exclusively on positive cases
Selective irrelevant negative cases
Negative case
Contrast cases that are positive on the DV, Y
Possibility Principle
Outcome has a real possibility, not just a nonzero, of occurring
Rule of Inclusion
Relevant if value on at least one X is positively related Y
Rule of Exclusion
Irrelevant if value on an eliminatory X predicts non-Y
Rule of Exclusion takes precedent over Rule of Inclusion
Negative case for the causes of genocide study: My theory Separatism based on ethic divisions feed genocide, Rule of Inclusion Colombia or Canada?, Rule of Exclusion Is Canada still a relevant negative case?
In "When Do the Dispossessed Protest?" Killian Clarke explores why refugees mobilize in some camps and not in others. Two of his cases are camps where refugees didn't mobilize.
Process tracing
1. Hypothesis that explains what happened
2. Observed implication or a fingerprint
3. Alternative hypothesis
4. Evidence
Process tracing (PT)
A research method for tracing causal processes using detailed, within-case analysis of how causal mechanisms operate in real-world cases
In PT we don't try to understand the causes, but how one of these variable linked to the outcome
