METHODOLOGY GUIDES · WRITTEN BY A WORKING META-ANALYST

The Decision Literacy Hub

Methodology guides for systematic review, meta-analysis, and evidence synthesis. Field manuals for researchers who refuse to guess — written by Dr. Esmaeel Saeedy Robat, published meta-analyst (Nature Human Behaviour 2026, forthcoming).

FIVE KNOWLEDGE PATHWAYS

Organized by the work, not the calendar

Articles are organized by the methodological phase they address — not by publication date. Find what you need by where you are in your research.

Question & Protocol

Framing answerable questions and building registered, defensible protocols.

Search & Screening

Comprehensive literature discovery and reproducible study selection.

Appraisal & Synthesis

Risk-of-bias, quantitative and narrative synthesis, GRADE certainty.

AI in Evidence Synthesis

AI-augmented workflows with human verification at every methodological checkpoint.

Applied Synthesis

Evidence work in HEOR, policy, education, and applied research contexts.

How to Frame an Answerable Review Question Across Six Frameworks

The choice between PICO, PECO, SPIDER, ECLIPSE, PCC, and PIRT is not just academic — it determines what evidence you find, what you can synthesize, and what you can defend. A walkthrough of how to choose, with worked examples from health, education, and policy research.

When to Use Meta-Analysis vs. Narrative Synthesis

The decision is not “more rigorous” vs. “less rigorous” — it is about what your evidence can support. Five concrete tests for making the call.

Why Systematic Reviews Fail: The Infrastructure Gap Before Analysis

Most systematic review failures stem from infrastructure absence — not statistical incompetence. The reasoning, with what the evidence shows about preventing it.

120+ articles across 8 knowledge pathways • Updated weekly

New guides, frameworks, and commentaries are published regularly and automatically organized within their respective pathways.

What You’ll Find Here

This is not a news blog. It is an evergreen knowledge base designed to support systematic thinking, methodological rigor, and judgment under uncertainty.

Methodological Guides

Protocol logic, PRISMA-P reasoning, search strategy design, bias assessment, and synthesis approaches. Learn the architecture of defensible evidence reviews.

Decision Frameworks

How to choose methods, interpret evidence, assess certainty, and defend conclusions. Navigate the gap between data and action with confidence.

AI & Judgment

Responsible use of AI in evidence synthesis. The Guided Verification-Driven (GVD) philosophy: AI accelerates, humans verify, judgment prevails.

Knowledge Pathways

Articles are organized into conceptual pathways that mirror the systematic review process from question to conclusion.

Framing Research & Decision Questions

PICO/PECO logic, stakeholder mapping, and defining answerable questions.

Protocol Design & Registration

PRISMA-P structure, pre-specification, and transparent planning.

Search Strategy & Study Selection

Database selection, Boolean logic, citation screening, and study flow.

Bias, Validity & Risk of Error

RoB 2, ROBINS-I, critical appraisal, and certainty of evidence.

Quantitative & Qualitative Synthesis

Meta-analysis, narrative synthesis, and integrating diverse evidence.

Interpretation, GRADE & Reporting

From findings to recommendations, structured transparency.

Evidence for Policy, Business & Practice

Applied decision-making in health, environment, law, and strategy.

AI-Enhanced Evidence Workflows

Leveraging AI responsibly while preserving methodological integrity.

The Four Phases of Evidence Mastery

From foundational decisions to advanced territories, your journey through the landscape of evidence synthesis.
