Research methods dialogue

Risk evidence comes from experiments, observational studies, models, case studies, expert judgement and lived experience, and each answers some questions well and others poorly. Methods dialogue is the comparison of those designs: what each assumes, where each fails and how evidence from different designs can be weighed together. This page sets out why methods choices carry governance consequences, how their quality can be checked, and who decides which evidence counts.

01In brief

The short answer.

Research methods dialogue is the comparison of study designs, from experiments and observational studies to models, case studies and expert judgement: what each assumes, where each fails and how evidence from different designs can be weighed together. Choices of method carry governance consequences, because they decide which evidence counts.

04The question

Research methods dialogue: how the risk develops.

Comparative methods and limitations. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mechanism

Hierarchies are misapplied

Evidence hierarchies built for clinical questions are applied to policy problems where trials are impossible or unethical. Relevant evidence from other designs is discounted, and decisions wait for evidence that cannot exist.

Mechanism

Assumptions stay hidden

Every model and estimate rests on assumptions about data, mechanisms and context. When these go unstated, users cannot judge transfer, and disputes about results are really unacknowledged disputes about assumptions.

Mechanism

Flexibility inflates findings

Many analytic choices remain open after data are seen. Choosing among them by result produces findings that do not replicate, and the problem compounds across a literature that favours positive results.

Mechanism

Context does not travel

An effect estimated in one setting depends on its institutions, population and timing. Transferring it without stating those conditions misleads decisions elsewhere, especially when evidence moves between very different settings.

05Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
PreregistrationRecording a study's hypotheses, design and analysis plan in a public registry before data are collected or analysed.
ReproducibilityObtaining the same results from the same data and code; replicability means obtaining consistent results from new data.
Certainty of evidenceA judgement of how confident one can be in a body of evidence, made with a stated framework such as GRADE.
Sensitivity analysisRepeating an analysis under different assumptions to show how much the result depends on them.
06Indicators

What is measured, and how well.

Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.

07Canvas

From sources to decisions.

The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

Pipeline canvas · Research methods dialogue as a run graphDesign, not a record
Research methods dialogue: systematic evidence synthesisA question is framed with its owner and a protocol registered; records are searched, screened and checked for eligibility by two reviewers; data are extracted, synthesised and graded for certainty before a brief is written.

10Core questions

What methods dialogue asks.

  • What kind of claim can this method support: correlation, causation, mechanism, possibility?
  • How do results change when a different but defensible method is used?
  • How can quantitative and qualitative evidence be combined without losing the strengths of either?
  • What are the known failure modes of the methods most used in this field?
11Mechanisms

Why methods comparison matters.

Analyses of the same data by different expert teams often reach different conclusions, because each team makes defensible choices about variables, models and assumptions. This variation is a real source of uncertainty that single studies hide. Comparing methods openly reveals it and helps users judge how robust a finding is.

Different methods also answer different questions. A randomized evaluation can show whether an intervention worked on average in one setting; a case study can show how and why it worked; a simulation can explore what might happen elsewhere. Confusion arises when one kind of evidence is asked to answer another kind of question.

12Methods and limits

Practices for comparing methods.

Methods comparison is most useful when it is routine rather than reserved for disputes. Several practices make it so, each with its own cost.

  1. 01

    Methods seminars

    Sessions where researchers present and challenge each other's methods. Limits: depend on openness and good faith.

  2. 02

    Multi-team analyses

    Several teams analyse the same question independently. Limits: resource-intensive.

  3. 03

    Causal inference frameworks

    Explicit causal assumptions and identification strategies, from causal inference and impact evaluation. Limits: assumptions cannot always be tested.

  4. 04

    Mixed-methods synthesis

    Combining statistical and qualitative evidence, with probability and statistics. Limits: no single agreed approach.

14Questions

Questions and answers.

Is a randomised trial always the strongest evidence?
No. It answers some causal questions well where it is feasible and ethical. Many policy questions need observational, quasi-experimental, modelling or qualitative evidence, judged against their own quality criteria.
What is preregistration?
Recording a study's hypotheses, design and analysis plan before seeing the outcome data. It separates planned from exploratory analysis and makes selective reporting visible.
Why do methods disagree?
Often because they rest on different assumptions or answer slightly different questions. Methods dialogue makes those differences explicit, so users can see which conclusion depends on which assumption.
Is one method best for studying risk?
No. Each method has strengths and limits. Robust conclusions usually draw on several.
Why do expert teams reach different conclusions from the same data?
Because many analytical choices are defensible, and different choices lead to different results. This is a real source of uncertainty.
Can I present my methods at a seminar?
Write to dialogues@globalriskforum.com. Seminars are scheduled only when their records are created; no date is promised in advance.
Are seminar records published?
Records are published in agreed form after participants have checked them for accuracy, and they state any attribution rule that applied.
