Hypothesis Generation
Structured frameworks for developing research hypotheses and experimental designs.
When to Use
- Starting a new research project
- Developing research questions
- Planning experiments
- Generating testable predictions
- Exploring competing explanations
Hypothesis Framework
Good Hypothesis Characteristics
A strong research hypothesis should be:
- Specific: Clear, precise statement
- Testable: Can be validated with data
- Falsifiable: Can potentially be proven wrong
- Grounded: Based on prior knowledge/theory
- Novel: Adds something new to the field
Hypothesis Types
| Type | Description | Example |
|---|
| Descriptive | Describes a phenomenon | "LLMs exhibit X behavior on task Y" |
| Relational | Proposes relationship | "Factor A correlates with outcome B" |
| Causal | Claims causation | "Intervention X causes improvement Y" |
| Comparative | Compares conditions | "Method A outperforms method B on task C" |
| Mechanistic | Explains how/why | "Effect X occurs because of mechanism Y" |
Hypothesis Development Process
Step 1: Identify the Gap
From your literature review, identify:
- What is known
- What is unknown or unclear
- What is contradictory
Document the gap:
## Research Gap
**Known**: [What prior work has established]
**Unknown**: [What remains to be discovered]
**Our Focus**: [Which unknown we address]
Step 2: Generate Initial Hypotheses
Use these prompts:
- "If [assumption] is true, then we should observe [prediction]"
- "Based on [theory/observation], we expect [outcome]"
- "Contrary to [current belief], we propose [alternative]"
Generate multiple hypotheses (aim for 3-5 initially).
Step 3: Develop Competing Hypotheses
For each hypothesis, identify:
- Alternative explanations: What else could explain the same observation?
- Null hypothesis: What if there's no effect?
- Opposite hypothesis: What if the effect is reversed?
Step 4: Operationalize
Convert abstract hypothesis to concrete, measurable terms:
| Abstract | Operationalized |
|---|
| "LLMs understand X" | "GPT-4 achieves >80% accuracy on benchmark Y" |
| "Method A is better" | "Method A improves F1 by >5% over baseline B" |
| "Training affects X" | "Models trained with X show Y behavior increase" |
Step 5: Design Tests
For each hypothesis, define:
- Data: What data is needed?
- Method: How will you test?
- Metrics: What measures success/failure?
- Threshold: What counts as support/rejection?
Competing Hypotheses Framework
Template
## Research Question
[Your main question]
### Hypothesis 1: [Name]
**Statement**: [Formal hypothesis]
**Rationale**: [Why this might be true]
**Prediction**: [What we expect to observe]
**Test**: [How to test]
### Hypothesis 2: [Alternative]
**Statement**: [Formal hypothesis]
**Rationale**: [Why this might be true]
**Prediction**: [What we expect to observe]
**Test**: [How to test]
### Hypothesis 3: [Null]
**Statement**: There is no significant effect
**Prediction**: No difference between conditions
**Test**: Statistical significance testing
### Decision Matrix
| Outcome | Supports H1 | Supports H2 | Supports H3 |
|---------|-------------|-------------|-------------|
| [Result A] | Yes | No | No |
| [Result B] | No | Yes | No |
| [Result C] | No | No | Yes |
Experimental Design
Variables
| Type | Definition | Example |
|---|
| Independent (IV) | What you manipulate | Model type, training data |
| Dependent (DV) | What you measure | Accuracy, F1, latency |
| Controlled | Held constant | Prompt template, temperature |
| Confounding | Could affect DV | Data contamination, model size |
Design Types
Between-subjects: Different conditions get different treatments
- Pros: No carryover effects
- Cons: Need more samples, individual differences
Within-subjects: Same subject gets all treatments
- Pros: Controls individual differences
- Cons: Order effects, fatigue
Factorial: Multiple IVs crossed
- Pros: Tests interactions
- Cons: More conditions needed
Control Strategies
- Baseline comparison: Compare against known baseline
- Ablation study: Remove components to test necessity
- Randomization: Random assignment to conditions
- Counterbalancing: Vary order across subjects/trials
Prediction Documentation
Template for Each Hypothesis
## Hypothesis: [Name]
### Formal Statement
[If X, then Y under conditions Z]
### Background
[Why we think this might be true]
### Predictions
#### Primary Prediction
- **Measure**: [What to measure]
- **Expected outcome**: [Specific prediction]
- **Threshold for support**: [Quantitative criterion]
#### Secondary Predictions
1. [Additional prediction 1]
2. [Additional prediction 2]
### Potential Confounds
- [Confound 1]: [How to address]
- [Confound 2]: [How to address]
### What Would Falsify This?
[Specific outcomes that would reject hypothesis]
Common Pitfalls
Avoid These
- Vague hypotheses: "Method A is good" → "Method A achieves >X on benchmark Y"
- Unfalsifiable claims: "LLMs may sometimes..." → "LLMs will show X in condition Y"
- Post-hoc hypothesizing: Generating hypothesis after seeing data
- Confirmation bias: Only looking for supporting evidence
- Missing null hypothesis: Not considering "no effect" possibility
Warning Signs
- Hypothesis can explain any outcome
- No clear way to measure
- Based on single observation
- Ignores contradictory evidence
- No alternative hypotheses considered
