01

Prerequisite

What needs to be finished first

Complete firstAssessable claim

The main claim is a clear statement whose validity can be discussed.

Turn a topic heading into a claim first.
02

Preparation

What needs to be ready before start

Materials

Statement cards with IDs, sources, support and attack arrows, and markers for jointly supporting reasons.

People / roles

People holding different positions, subject reviewers and facilitator.

Pre-read

Collect one clear main claim and relevant statements with sources; define terms and scope.

Time needed

45–90 minutes initial mapping; evidence checking separately

Setup

Display the main claim; prepare statement cards with IDs and distinct support and attack links.

03

Core question

The one question this method answers

Which reasons support the claim, which objections weaken it and what evidence is missing?

04

Flow

Phases with goal, actions, output and pitfall

Argument mapping represents claims and their reasoning relationships. Reasons can support independently or only jointly; objections target a claim or its inference, while evidence supports specific premises.

Argument Mapping· worksheet

Fictional example

Argument mapping represents claims and their reasoning relationships. Reasons can support independently or only jointly; objections target a claim or its inference, while evidence supports specific premises.

Main claim

Which precise claim are we assessing?

Fictional, C: we should first test course launch with a small pilot group.

Reasons and links

Which premises support which statement independently or jointly?

P1: the flow contains untested steps. P2: early trials can reveal such failures before broad use. P1 AND P2 support C. P3: a pilot group is available, supporting feasibility of C.

Objection and target

Which claim or inference is attacked by which objection?

O1 attacks C: a pilot could jeopardise the launch date. O2 weakens P2: the pilot group might not cover important usage situations.

Rebuttal

Which response addresses which specific objection?

R1 to O1: a two-day pilot fits the existing buffer if the team confirms capacity. O2 remains open.

Evidence and status

Which source supports which premise and what assumptions remain open?

Fictional test plan E1 supports P1; schedule E2 supports P3. R1 lacks capacity confirmation. C remains conditionally recommended; investigate representative scenarios for O2.

All example details are fictional and illustrate the application.

  1. 1

    Claim

    Claim

    Goal

    Main claim

    Inputs for this step

    • Initial question
    • Terms

    Actions

    • State a precise main claim with scope and clarify ambiguous terms.
    • Distinguish factual claim from action recommendation.

    Output

    Main claim

    Can the claim meaningfully be challenged or supported?

    Quality check

    Can the claim meaningfully be challenged or supported?

    Pitfall

    The centre contains only the topic digitalisation. State a concrete proposition or recommendation.

    Timing: 5–10 minutes

  2. 2

    Reasons

    Link reasons

    Goal

    Reasoning structure

    Inputs for this step

    • Claim
    • Supporting statements

    Actions

    • Capture reasons as individual statements and link each to the claim it supports.
    • Group jointly necessary premises; connect independent reasons separately.

    Output

    Reasoning structure

    Is it clear which reasons work only jointly?

    Quality check

    Is it clear which reasons work only jointly?

    Pitfall

    A list of keywords replaces logical relationships. Read each arrow as a because statement and add missing premises.

    Timing: 15–25 minutes

  3. 3

    Objections

    Examine objections

    Goal

    Objections and rebuttals

    Inputs for this step

    • Reasoning structure
    • Opposing positions

    Actions

    • Add strong objections to claims or inferences and attach rebuttals to their targets.
    • Represent positions fairly and retain unresolved disagreement.

    Output

    Objections and rebuttals

    Does the objection address the actual claim?

    Quality check

    Does the objection address the actual claim?

    Pitfall

    An easily refuted caricature replaces the opposing view. Have its proponents confirm the opposing position.

    Timing: 15–25 minutes

  4. 4

    Judgement

    Evidence and judgement

    Goal

    Reasoned judgement

    Inputs for this step

    • Map
    • Sources and counterevidence

    Actions

    • Attach sources to specific premises; assess reliability and inference separately.
    • State the result as supported, qualified or open and assign missing-evidence checks.

    Output

    Reasoned judgement

    Are source quality and inference checked separately?

    Quality check

    Are source quality and inference checked separately?

    Pitfall

    A credible source is assumed to validate any conclusion. Check whether the source supports that premise and whether the conclusion follows.

    Timing: 15–30 minutes

Stop criteria

When to pause, resolve prerequisites, or choose another approach

Many reasons do not replace sound reasoning: examine premise truth and inference separately and actively seek counterevidence.
