Grad paradigms

Paradigm Theory (Kuhn)

Overview

Kuhn's paradigm theory explains scientific progress not as linear accumulation but as a cyclical process: normal science operates within a paradigm until anomalies accumulate, triggering crisis and eventually a revolutionary paradigm shift. The new paradigm is incommensurable with the old — they literally see different worlds.

When to Use

• Analyzing why a scientific or professional field resists new ideas
• Tracing historical shifts in dominant frameworks within a discipline
• Understanding why debates between competing schools seem irresolvable
• Evaluating whether a field is in normal science, crisis, or revolutionary phase

When NOT to Use

• When analyzing incremental, non-revolutionary knowledge growth (use Lakatos instead)
• When the focus is on individual discovery rather than community-level shifts
• When normative evaluation of which paradigm is "better" is required (Kuhn is descriptive)

Assumptions

IRON LAW: Scientists working within a paradigm do NOT test the paradigm —
they solve puzzles defined by it. Paradigm change is a social-political
process, not a purely rational one.

Key assumptions:

1. Science operates within shared paradigms (exemplars + disciplinary matrix)
2. Normal science is puzzle-solving, not paradigm-testing
3. Anomalies are initially dismissed, not immediately investigated
4. Paradigm shifts involve gestalt switches — not gradual conversion

Methodology

Step 1: Identify the Paradigm

Define the dominant paradigm: shared exemplars, accepted methods, ontological commitments, and the community that holds them.

Step 2: Map Normal Science Activity

Identify puzzle-solving within the paradigm — what questions are considered legitimate, what methods are standard, what counts as a solution.

Step 3: Trace Anomalies and Crisis

Document anomalies (persistent puzzles the paradigm cannot solve), and assess whether they have accumulated to crisis level — marked by proliferation of ad hoc modifications and questioning of fundamentals.

Step 4: Assess Revolution or Stability

Determine whether a rival paradigm has emerged, evaluate incommensurability with the old paradigm, and trace the social process of conversion (generational replacement, institutional power shifts).

Output Format

## Paradigm Analysis: [Context]

### Dominant Paradigm
- Core exemplars: [foundational achievements that define the paradigm]
- Disciplinary matrix: [shared values, methods, symbolic generalizations]
- Community: [who subscribes to this paradigm]

### Normal Science Phase
- Legitimate puzzles: [questions the paradigm defines as worth solving]
- Standard methods: [accepted approaches]
- Anomalies identified: [persistent unsolved puzzles]

### Crisis Assessment
- Severity: [pre-crisis / emerging crisis / full crisis]
- Ad hoc modifications: [patches to save the paradigm]
- Competing candidates: [alternative paradigms emerging]

### Paradigm Shift Evaluation
- Rival paradigm: [description if one exists]
- Incommensurability points: [where old and new paradigms talk past each other]
- Conversion dynamics: [generational, institutional, evidential factors]

### Implications
1. [Current phase of the field]
2. [Likelihood and direction of potential shift]

Gotchas

• Kuhn's "paradigm" has been criticized for vagueness — he used it in 21+ senses; be explicit about which sense you mean
• Incommensurability does NOT mean paradigms cannot be compared at all — it means translation is imperfect
• Not all fields have clear paradigms; Kuhn's model fits natural sciences best and applies less cleanly to social sciences
• Normal science is not inferior to revolutionary science — it is productive and necessary
• The winner of a paradigm shift is not necessarily "more true" — it solves more puzzles that the community currently cares about
• Do not conflate paradigm shift with any theoretical change — Kuhn reserved it for fundamental restructuring
