hypothesis-gen is a Claude skill that runs a structured workflow to formulate testable scientific hypotheses from observations, gaps, or preliminary data.

About

hypothesis-gen is a Claude skill that runs a structured workflow for generating testable scientific hypotheses from observations, gaps, or preliminary data. A researcher uses it to formulate H0/H1, define variables, and score and prioritize candidate hypotheses before designing experiments. It matters because it turns a vague research question into ranked, falsifiable hypotheses with a consistent evaluation rubric.

  • Structured 5-step workflow to formulate testable scientific hypotheses from observations or gaps
  • Scores each hypothesis on testability, falsifiability, novelty, mechanism, feasibility and impact
  • Explicitly not for testing hypotheses or running experiments

What it does

Formulate and prioritize testable scientific hypotheses (H0/H1) from observations, gaps, or preliminary data.

Who is it for?

Turning observations, anomalies, or knowledge gaps into ranked, falsifiable scientific hypotheses.

Skip if: Testing or verifying hypotheses and designing experiments, which the docs explicitly exclude.

When should I use this skill?

The user needs to generate hypotheses, explain an observation, or formulate H0 and H1 from data.

What you get

A ranked set of formally stated hypotheses with variables, evaluation scores, and suggested tests.

  • Formally stated hypotheses (H0/H1)
  • Variable definitions
  • Evaluation scores and priority ranking

By the numbers

  • 5-step generation workflow
  • 6 evaluation criteria scored 1-5
  • 8-item quality checklist

Hypothesis Generation Skill

Structured workflow for generating testable scientific hypotheses.

When to Use

  • "Generate hypotheses for this research question"
  • "What could explain this observation?"
  • "Propose testable ideas based on this data"
  • "Help me formulate H0 and H1"
  • "What hypotheses does this gap suggest?"

When NOT to Use

  • Testing/verifying hypotheses (use scienceclaw-verification)
  • Designing experiments (use experimental-design)
  • Literature searching (use literature-search)
  • Writing full papers (use paper-writing)

Generation Workflow

Step 1: Observe

Identify the phenomenon, anomaly, or gap:

  • What was observed?
  • What is unexpected or unexplained?
  • What contradicts existing theory?
  • What data pattern needs explanation?

Step 2: Contextualize

Ground in existing literature:

  • What do current theories predict?
  • What related findings exist?
  • Where are the knowledge gaps?
  • What alternative explanations exist?

Step 3: Formulate

State the hypothesis formally:

Template: "If [independent variable/condition], then [predicted effect on dependent variable], because [proposed mechanism]."

Null Hypothesis (H0): No effect / no difference / no relationship Alternative Hypothesis (H1): The predicted effect exists Directional: Specify direction (increase/decrease) when justified

Step 4: Evaluate

Score each hypothesis on:

CriterionScore (1-5)Description
Testability_Can be experimentally tested?
Falsifiability_Can be proven wrong?
Novelty_How new is this idea?
Mechanism_Is the proposed mechanism plausible?
Feasibility_Can current methods test it?
Impact_How significant if confirmed?

Step 5: Prioritize

Rank hypotheses by:

  • Total evaluation score
  • Risk-reward ratio (impact / feasibility)
  • Alignment with available resources
  • Potential for publication

Output Format

## Hypothesis [N]: [Short title]

**Statement**: If [condition], then [prediction], because [mechanism].
**H0**: [Null hypothesis]
**H1**: [Alternative hypothesis]

**Variables**:
- Independent: [variable]
- Dependent: [variable]
- Controls: [variables to hold constant]

**Evaluation**: Testability=[X] Falsifiability=[X] Novelty=[X] Mechanism=[X] Feasibility=[X] Impact=[X]
**Priority Score**: [Total/30]

**Key References**: [relevant citations]
**Suggested Test**: [brief experimental approach]

Quality Checklist

  • [ ] Hypothesis is specific and testable
  • [ ] Variables are clearly identified
  • [ ] Mechanism is plausible given known science
  • [ ] Null hypothesis is properly stated
  • [ ] Predictions are measurable
  • [ ] At least one path to falsification exists
  • [ ] Novel relative to existing literature
  • [ ] Ethical considerations addressed

FAQ

What is this skill NOT for?

It is not for testing or verifying hypotheses, designing experiments, literature searching, or writing full papers.

How are hypotheses evaluated?

Each is scored 1-5 on testability, falsifiability, novelty, mechanism, feasibility, and impact, then prioritized by total score and risk-reward.
