hypothesis-generation

# Scientific Hypothesis Generation

## Overview

Hypothesis generation is a systematic process for developing testable explanations. Formulate evidence-based hypotheses from observations, design experiments, explore competing explanations, and develop predictions. Apply this skill for scientific inquiry across domains.

## When to Use This Skill

This skill should be used when:
- Developing hypotheses from observations or preliminary data
- Designing experiments to test scientific questions
- Exploring competing explanations for phenomena
- Formulating testable predictions for research
- Conducting literature-based hypothesis generation
- Planning mechanistic studies across scientific domains

## Visual Enhancement with Scientific Schematics

**⚠️ MANDATORY: Every hypothesis generation report MUST include at least 1-2 AI-generated figures using the scientific-schematics skill.**

This is not optional. Hypothesis reports without visual elements are incomplete. Before finalizing any document:
1. Generate at minimum ONE schematic or diagram (e.g., hypothesis framework showing competing explanations)
2. Prefer 2-3 figures for comprehensive reports (mechanistic pathway, experimental design flowchart, prediction decision tree)

**How to generate figures:**
- Use the **scientific-schematics** skill to generate AI-powered publication-quality diagrams
- Simply describe your desired diagram in natural language
- Nano Banana Pro will automatically generate, review, and refine the schematic

**How to generate schematics:**
```bash
python scripts/generate_schematic.py "your diagram description" -o figures/output.png
```

The AI will automatically:
- Create publication-quality images with proper formatting
- Review and refine through multiple iterations
- Ensure accessibility (colorblind-friendly, high contrast)
- Save outputs in the figures/ directory

**When to add schematics:**
- Hypothesis framework diagrams showing competing explanations
- Experimental design flowcharts
- Mechanistic pathway diagrams
- Prediction decision trees
- Causal relationship diagrams
- Theoretical model visualizations
- Any complex concept that benefits from visualization

For detailed guidance on creating schematics, refer to the scientific-schematics skill documentation.

## Workflow

Follow this systematic process to generate robust scientific hypotheses:

### 1. Understand the Phenomenon

Start by clarifying the observation, question, or phenomenon that requires explanation:

- Identify the core observation or pattern that needs explanation
- Define the scope and boundaries of the phenomenon
- Note any constraints or specific contexts
- Clarify what is already known vs. what is uncertain
- Identify the relevant scientific domain(s)

### 2. Conduct Comprehensive Literature Search

Search existing scientific literature to ground hypotheses in current evidence. Use both PubMed (for biomedical topics) and general web search (for broader scientific domains):

**For biomedical topics:**
- Use WebFetch with PubMed URLs to access relevant literature
- Search for recent reviews, meta-analyses, and primary research
- Look for similar phenomena, related mechanisms, or analogous systems

**For all scientific domains:**
- Use WebSearch to find recent papers, preprints, and reviews
- Search for established theories, mechanisms, or frameworks
- Identify gaps in current understanding

**Search strategy:**
- Begin with broad searches to understand the landscape
- Narrow to specific mechanisms, pathways, or theories
- Look for contradictory findings or unresolved debates
- Consult `references/literature_search_strategies.md` for detailed search techniques

### 3. Synthesize Existing Evidence

Analyze and integrate findings from literature search:

- Summarize current understanding of the phenomenon
- Identify established mechanisms or theories that may apply
- Note conflicting evidence or alternative viewpoints
- Recognize gaps, limitations, or unanswered questions
- Identify analogies from related systems or domains

### 4. Generate Competing Hypotheses

Develop 3-5 distinct hypotheses that could explain the phenomenon. Each hypothesis should:

- Provide a mechanistic explanation (not just description)
- Be distinguishable from other hypotheses
- Draw on evidence from the literature synthesis
- Consider different levels of explanation (molecular, cellular, systemic, population, etc.)

**Strategies for generating hypotheses:**
- Apply known mechanisms from analogous systems
- Consider multiple causative pathways
- Explore different scales of explanation
- Question assumptions in existing explanations
- Combine mechanisms in novel ways

### 5. Evaluate Hypothesis Quality

Assess each hypothesis against established quality criteria from `references/hypothesis_quality_criteria.md`:

**Testability:** Can the hypothesis be empirically tested?
**Falsifiability:** What observations would disprove it?
**Parsimony:** Is it the simplest explanation that fits the evidence?
**Explanatory Power:** How much of the phenomenon does it explain?
**Scope:** What range of observations does it cover?
**Consistency:** Does it align with established principles?
**Novelty:** Does it offer new insights beyond existing explanations?

Explicitly note the strengths and weaknesses of each hypothesis.

### 6. Design Experimental Tests

For each viable hypothesis, propose specific experiments or studies to test it. Consult `references/experimental_design_patterns.md` for common approaches:

**Experimental design elements:**
- What would be measured or observed?
- What comparisons or controls are needed?
- What methods or techniques would be used?
- What sample sizes or statistical approaches are appropriate?
- What are potential confounds and how to address them?

**Consider multiple approaches:**
- Laboratory experiments (in vitro, in vivo, computational)
- Observational studies (cross-sectional, longitudinal, case-control)
- Clinical trials (if applicable)
- Natural experiments or quasi-experimental designs

### 7. Formulate Testable Predictions

For each hypothesis, generate specific, quantitative predictions:

- State what should be observed if the hypothesis is correct
- Specify expected direction and magnitude of effects when possible
- Identify conditions under which predictions should hold
- Distinguish predictions between competing hypotheses
- Note predictions that would falsify the hypothesis

### 8. Present Structured Output

Generate a professional LaTeX document using the template in `assets/hypothesis_report_template.tex`. The report should be well-formatted with colored boxes for visual organization and divided into a concise main text with comprehensive appendices.

**Document Structure:**

**Main Text (Maximum 4 pages):**
1. **Executive Summary** - Brief overview in summary box (0.5-1 page)
2. **Competing Hypotheses** - Each hypothesis in its own colored box with brief mechanistic explanation and key evidence (2-2.5 pages for 3-5 hypotheses)
   - **IMPORTANT:** Use `\newpage` before each hypothesis box to prevent content overflow
   - Each box should be ≤0.6 pages maximum
3. **Testable Predictions** - Key predictions in amber boxes (0.5-1 page)
4. **Critical Comparisons** - Priority comparison boxes (0.5-1 page)

Keep main text highly concise - only the most essential information. All details go to appendices.

**Page Break Strategy:**
- Always use `\newpage` before hypothesis boxes to ensure they start on fresh pages
- This prevents content from overflowing off page boundaries
- LaTeX boxes (tcolorbox) do not automatically break across pages

**Appendices (Comprehensive, Detailed):**
- **Appendix A:** Comprehensive literature review with extensive citations
- **Appendix B:** Detailed experimental designs with full protocols
- **Appendix C:** Quality assessment tables and detailed evaluations
- **Appendix D:** Supplementary evidence and analogous systems

**Colored Box Usage:**

Use the custom box environments from `hypothesis_generation.sty`:

- `hypothesisbox1` through `hypothesisbox5` - For each competing hypothesis (blue, green, purple, teal, orange)
- `predictionbox` - For testable predictions (amber)
- `comparisonbox` - For critical comparisons (steel gray)
- `evidencebox` - For supporting evidence highlights (light blue)
- `summarybox` - For executive summary (blue)

**Each hypothesis box should contain (keep concise for 4-page limit):**
- **Mechanistic Explanation:** 1-2 brief paragraphs (6-10 sentences max) explaining HOW and WHY
- **Key Supporting Evidence:** 2-3 bullet points with citations (most important evidence only)
- **Core Assumptions:** 1-2 critical assumptions

All detailed explanations, additional evidence, and comprehensive discussions belong in the appendices.

**Critical Overflow Prevention:**
- Insert `\newpage` before each hypothesis box to start it on a fresh page
- Keep each complete hypothesis box to ≤0.6 pages (approximately 15-20 lines of content)
- If content exceeds this, move additional details to Appendix A
- Never let boxes overflow off page boundaries - this creates unreadable PDFs

**Citation Requirements:**

Aim for extensive citation to support all claims:
- **Main text:** 10-15 key citations for most important evidence only (keep concise for 4-page limit)
- **Appendix A:** 40-70+ comprehensive citations covering all relevant literature
- **Total target:** 50+ references in bibliography

Main text citations should be selective - cite only the most critical papers. All comprehensive citation and detailed literature discussion belongs in the appendices. Use `\citep{author2023}` for parenthetical citations.

**LaTeX Compilation:**

The template requires XeLaTeX or LuaLaTeX for proper rendering:

```bash
xelatex hypothesis_report.tex
bibtex hypothesis_report
xelatex hypothesis_report.tex
xelatex hypothesis_report.tex
```

**Required packages:** The `hypothesis_generation.sty` style package must be in the same directory or LaTeX path. It requires: tcolorbox, xcolor, fontspec, fancyhdr, titlesec, enumitem, booktabs, natbib.

**Page Overflow Prevention:**

To prevent content from overflowing on pages, follow these critical guidelines:

1. **Monitor Box Content Length:** Each hypothesis box should fit comfortably on a single page. If content exceeds ~0.7 pages, it will likely overflow.

2. **Use Strategic Page Breaks:** Insert `\newpage` before boxes that contain substantial content:
   ```latex
   \newpage
   \begin{hypothesisbox1}[Hypothesis 1: Title]
   % Long content here
   \end{hypothesisbox1}
   ```

3. **Keep Main Text Boxes Concise:** For the 4-page main text limit:
   - Each hypothesis box: Maximum 0.5-0.6 pages
   - Mechanistic explanation: 1-2 brief paragraphs only (6-10 sentences max)
   - Key evidence: 2-3 bullet points only
   - Core assumptions: 1-2 items only
   - If content is longer, move details to appendices

4. **Break Long Content:** If a hypothesis requires extensive explanation, split across main text and appendix:
   - Main text box: Brief mechanistic overview + 2-3 key evidence points
   - Appendix A: Detailed mechanism explanation, comprehensive evidence, extended discussion

5. **Test Page Boundaries:** Before each new box, consider if remaining page space is sufficient. If less than 0.6 pages remain, use `\newpage` to start the box on a fresh page.

6. **Appendix Page Management:** In appendices, use `\newpage` between major sections to avoid overflow in detailed content areas.

**Quick Reference:** See `assets/FORMATTING_GUIDE.md` for detailed examples of all box types, color schemes, and common formatting patterns.

## Quality Standards

Ensure all generated hypotheses meet these standards:

- **Evidence-based:** Grounded in existing literature with citations
- **Testable:** Include specific, measurable predictions
- **Mechanistic:** Explain how/why, not just what
- **Comprehensive:** Consider alternative explanations
- **Rigorous:** Include experimental designs to test predictions

Prefer 2-3 figures for comprehensive reports (mechanistic pathway, experimental design flowchart, prediction decision tree)\r\n\r\n**How to generate figures:**\r\n- Use the **scientific-schematics** skill to generate AI-powered publication-quality diagrams\r\n- Simply describe your desired diagram in natural language\r\n- Nano Banana Pro will automatically generate, review, and refine the schematic\r\n\r\n**How to generate schematics:**\r\n```bash\r\npython scripts/generate_schematic.py \"your diagram description\" -o figures/output.png\r\n```\r\n\r\nThe AI will automatically:\r\n- Create publication-quality images with proper formatting\r\n- Review and refine through multiple iterations\r\n- Ensure accessibility (colorblind-friendly, high contrast)\r\n- Save outputs in the figures/ directory\r\n\r\n**When to add schematics:**\r\n- Hypothesis framework diagrams showing competing explanations\r\n- Experimental design flowcharts\r\n- Mechanistic pathway diagrams\r\n- Prediction decision trees\r\n- Causal relationship diagrams\r\n- Theoretical model visualizations\r\n- Any complex concept that benefits from visualization\r\n\r\nFor detailed guidance on creating schematics, refer to the scientific-schematics skill documentation.\r\n\r\n---\r\n\r\n## Workflow\r\n\r\nFollow this systematic process to generate robust scientific hypotheses:\r\n\r\n### 1. Understand the Phenomenon\r\n\r\nStart by clarifying the observation, question, or phenomenon that requires explanation:\r\n\r\n- Identify the core observation or pattern that needs explanation\r\n- Define the scope and boundaries of the phenomenon\r\n- Note any constraints or specific contexts\r\n- Clarify what is already known vs. what is uncertain\r\n- Identify the relevant scientific domain(s)\r\n\r\n### 2. Conduct Comprehensive Literature Search\r\n\r\nSearch existing scientific literature to ground hypotheses in current evidence. Use both PubMed (for biomedical topics) and general web search (for broader scientific domains):\r\n\r\n**For biomedical topics:**\r\n- Use WebFetch with PubMed URLs to access relevant literature\r\n- Search for recent reviews, meta-analyses, and primary research\r\n- Look for similar phenomena, related mechanisms, or analogous systems\r\n\r\n**For all scientific domains:**\r\n- Use WebSearch to find recent papers, preprints, and reviews\r\n- Search for established theories, mechanisms, or frameworks\r\n- Identify gaps in current understanding\r\n\r\n**Search strategy:**\r\n- Begin with broad searches to understand the landscape\r\n- Narrow to specific mechanisms, pathways, or theories\r\n- Look for contradictory findings or unresolved debates\r\n- Consult `references/literature_search_strategies.md` for detailed search techniques\r\n\r\n### 3. Synthesize Existing Evidence\r\n\r\nAnalyze and integrate findings from literature search:\r\n\r\n- Summarize current understanding of the phenomenon\r\n- Identify established mechanisms or theories that may apply\r\n- Note conflicting evidence or alternative viewpoints\r\n- Recognize gaps, limitations, or unanswered questions\r\n- Identify analogies from related systems or domains\r\n\r\n### 4. Generate Competing Hypotheses\r\n\r\nDevelop 3-5 distinct hypotheses that could explain the phenomenon. Each hypothesis should:\r\n\r\n- Provide a mechanistic explanation (not just description)\r\n- Be distinguishable from other hypotheses\r\n- Draw on evidence from the literature synthesis\r\n- Consider different levels of explanation (molecular, cellular, systemic, population, etc.)\r\n\r\n**Strategies for generating hypotheses:**\r\n- Apply known mechanisms from analogous systems\r\n- Consider multiple causative pathways\r\n- Explore different scales of explanation\r\n- Question assumptions in existing explanations\r\n- Combine mechanisms in novel ways\r\n\r\n### 5. Evaluate Hypothesis Quality\r\n\r\nAssess each hypothesis against established quality criteria from `references/hypothesis_quality_criteria.md`:\r\n\r\n**Testability:** Can the hypothesis be empirically tested?\r\n**Falsifiability:** What observations would disprove it?\r\n**Parsimony:** Is it the simplest explanation that fits the evidence?\r\n**Explanatory Power:** How much of the phenomenon does it explain?\r\n**Scope:** What range of observations does it cover?\r\n**Consistency:** Does it align with established principles?\r\n**Novelty:** Does it offer new insights beyond existing explanations?\r\n\r\nExplicitly note the strengths and weaknesses of each hypothesis.\r\n\r\n### 6. Design Experimental Tests\r\n\r\nFor each viable hypothesis, propose specific experiments or studies to test it. Consult `references/experimental_design_patterns.md` for common approaches:\r\n\r\n**Experimental design elements:**\r\n- What would be measured or observed?\r\n- What comparisons or controls are needed?\r\n- What methods or techniques would be used?\r\n- What sample sizes or statistical approaches are appropriate?\r\n- What are potential confounds and how to address them?\r\n\r\n**Consider multiple approaches:**\r\n- Laboratory experiments (in vitro, in vivo, computational)\r\n- Observational studies (cross-sectional, longitudinal, case-control)\r\n- Clinical trials (if applicable)\r\n- Natural experiments or quasi-experimental designs\r\n\r\n### 7. Formulate Testable Predictions\r\n\r\nFor each hypothesis, generate specific, quantitative predictions:\r\n\r\n- State what should be observed if the hypothesis is correct\r\n- Specify expected direction and magnitude of effects when possible\r\n- Identify conditions under which predictions should hold\r\n- Distinguish predictions between competing hypotheses\r\n- Note predictions that would falsify the hypothesis\r\n\r\n### 8. Present Structured Output\r\n\r\nGenerate a professional LaTeX document using the template in `assets/hypothesis_report_template.tex`. The report should be well-formatted with colored boxes for visual organization and divided into a concise main text with comprehensive appendices.\r\n\r\n**Document Structure:**\r\n\r\n**Main Text (Maximum 4 pages):**\r\n1. **Executive Summary** - Brief overview in summary box (0.5-1 page)\r\n2. **Competing Hypotheses** - Each hypothesis in its own colored box with brief mechanistic explanation and key evidence (2-2.5 pages for 3-5 hypotheses)\r\n   - **IMPORTANT:** Use `\\newpage` before each hypothesis box to prevent content overflow\r\n   - Each box should be ≤0.6 pages maximum\r\n3. **Testable Predictions** - Key predictions in amber boxes (0.5-1 page)\r\n4. **Critical Comparisons** - Priority comparison boxes (0.5-1 page)\r\n\r\nKeep main text highly concise - only the most essential information. All details go to appendices.\r\n\r\n**Page Break Strategy:**\r\n- Always use `\\newpage` before hypothesis boxes to ensure they start on fresh pages\r\n- This prevents content from overflowing off page boundaries\r\n- LaTeX boxes (tcolorbox) do not automatically break across pages\r\n\r\n**Appendices (Comprehensive, Detailed):**\r\n- **Appendix A:** Comprehensive literature review with extensive citations\r\n- **Appendix B:** Detailed experimental designs with full protocols\r\n- **Appendix C:** Quality assessment tables and detailed evaluations\r\n- **Appendix D:** Supplementary evidence and analogous systems\r\n\r\n**Colored Box Usage:**\r\n\r\nUse the custom box environments from `hypothesis_generation.sty`:\r\n\r\n- `hypothesisbox1` through `hypothesisbox5` - For each competing hypothesis (blue, green, purple, teal, orange)\r\n- `predictionbox` - For testable predictions (amber)\r\n- `comparisonbox` - For critical comparisons (steel gray)\r\n- `evidencebox` - For supporting evidence highlights (light blue)\r\n- `summarybox` - For executive summary (blue)\r\n\r\n**Each hypothesis box should contain (keep concise for 4-page limit):**\r\n- **Mechanistic Explanation:** 1-2 brief paragraphs (6-10 sentences max) explaining HOW and WHY\r\n- **Key Supporting Evidence:** 2-3 bullet points with citations (most important evidence only)\r\n- **Core Assumptions:** 1-2 critical assumptions\r\n\r\nAll detailed explanations, additional evidence, and comprehensive discussions belong in the appendices.\r\n\r\n**Critical Overflow Prevention:**\r\n- Insert `\\newpage` before each hypothesis box to start it on a fresh page\r\n- Keep each complete hypothesis box to ≤0.6 pages (approximately 15-20 lines of content)\r\n- If content exceeds this, move additional details to Appendix A\r\n- Never let boxes overflow off page boundaries - this creates unreadable PDFs\r\n\r\n**Citation Requirements:**\r\n\r\nAim for extensive citation to support all claims:\r\n- **Main text:** 10-15 key citations for most important evidence only (keep concise for 4-page limit)\r\n- **Appendix A:** 40-70+ comprehensive citations covering all relevant literature\r\n- **Total target:** 50+ references in bibliography\r\n\r\nMain text citations should be selective - cite only the most critical papers. All comprehensive citation and detailed literature discussion belongs in the appendices. Use `\\citep{author2023}` for parenthetical citations.\r\n\r\n**LaTeX Compilation:**\r\n\r\nThe template requires XeLaTeX or LuaLaTeX for proper rendering:\r\n\r\n```bash\r\nxelatex hypothesis_report.tex\r\nbibtex hypothesis_report\r\nxelatex hypothesis_report.tex\r\nxelatex hypothesis_report.tex\r\n```\r\n\r\n**Required packages:** The `hypothesis_generation.sty` style package must be in the same directory or LaTeX path. It requires: tcolorbox, xcolor, fontspec, fancyhdr, titlesec, enumitem, booktabs, natbib.\r\n\r\n**Page Overflow Prevention:**\r\n\r\nTo prevent content from overflowing on pages, follow these critical guidelines:\r\n\r\n1. **Monitor Box Content Length:** Each hypothesis box should fit comfortably on a single page. If content exceeds ~0.7 pages, it will likely overflow.\r\n\r\n2. **Use Strategic Page Breaks:** Insert `\\newpage` before boxes that contain substantial content:\r\n   ```latex\r\n   \\newpage\r\n   \\begin{hypothesisbox1}[Hypothesis 1: Title]\r\n   % Long content here\r\n   \\end{hypothesisbox1}\r\n   ```\r\n\r\n3. **Keep Main Text Boxes Concise:** For the 4-page main text limit:\r\n   - Each hypothesis box: Maximum 0.5-0.6 pages\r\n   - Mechanistic explanation: 1-2 brief paragraphs only (6-10 sentences max)\r\n   - Key evidence: 2-3 bullet points only\r\n   - Core assumptions: 1-2 items only\r\n   - If content is longer, move details to appendices\r\n\r\n4. **Break Long Content:** If a hypothesis requires extensive explanation, split across main text and appendix:\r\n   - Main text box: Brief mechanistic overview + 2-3 key evidence points\r\n   - Appendix A: Detailed mechanism explanation, comprehensive evidence, extended discussion\r\n\r\n5. **Test Page Boundaries:** Before each new box, consider if remaining page space is sufficient. If less than 0.6 pages remain, use `\\newpage` to start the box on a fresh page.\r\n\r\n6. **Appendix Page Management:** In appendices, use `\\newpage` between major sections to avoid overflow in detailed content areas.\r\n\r\n**Quick Reference:** See `assets/FORMATTING_GUIDE.md` for detailed examples of all box types, color schemes, and common formatting patterns.\r\n\r\n## Quality Standards\r\n\r\nEnsure all generated hypotheses meet these standards:\r\n\r\n- **Evidence-based:** Grounded in existing literature with citations\r\n- **Testable:** Include specific, measurable predictions\r\n- **Mechanistic:** Explain how/why, not just what\r\n- **Comprehensive:** Consider alternative explanations\r\n- **Rigorous:** Include experimental designs to test predictions\r\n\r\n## Resources\r\n\r\n### references/\r\n\r\n- `hypothesis_quality_criteria.md` - Framework for evaluating hypothesis quality (testability, falsifiability, parsimony, explanatory power, scope, consistency)\r\n- `experimental_design_patterns.md` - Common experimental approaches across domains (RCTs, observational studies, lab experiments, computational models)\r\n- `literature_search_strategies.md` - Effective search techniques for PubMed and general scientific sources\r\n\r\n### assets/\r\n\r\n- `hypothesis_generation.sty` - LaTeX style package providing colored boxes, professional formatting, and custom environments for hypothesis reports\r\n- `hypothesis_report_template.tex` - Complete LaTeX template with main text structure and comprehensive appendix sections\r\n- `FORMATTING_GUIDE.md` - Quick reference guide with examples of all box types, color schemes, citation practices, and troubleshooting tips\r\n\r\n### Related Skills\r\n\r\nWhen preparing hypothesis-driven research for publication, consult the **venue-templates** skill for writing style guidance:\r\n- `venue_writing_styles.md` - Master guide comparing styles across venues\r\n- Venue-specific guides for Nature/Science, Cell Press, medical journals, and ML/CS conferences\r\n- `reviewer_expectations.md` - What reviewers look for when evaluating research hypotheses"
