From persuasion to reasoned judgement

An argument can be persuasive and still contain a gap. These stations move from claim and reason through the structure of an inference to what remains open.

← Teaching and study

Which reasons support a judgement, and under which conditions must it be revised?

Case study

Fictional exercise written for this material. Not empirical data.

An imagined study group recommends a new learning app: “Since using it, our results have improved. Nobody has proved that it does not help. Therefore everyone should use it.” Previous study time, task differences and alternative explanations are not given.

Materials and schedule

Teaching notes

Approximately ages 16+, advanced school groups, higher education and adult learning.

Read short specialist texts; distinguish statement, observation and interpretation. Responses may be spoken, written or given as an annotated sketch.

Learning objectives

Identify claim, reason and implicit warrant.
Test counterexamples and an argument’s scope.
Formulate an open question without treating missing knowledge as proof.

5 min introduction · 20 comparing two stations · 10 evidence and counterexample · 10 shared reflection

The worksheet contains two selected stations. Read definitions, open sources and separate observation from inference.

Assignment

Separate the three sentences into observation, asserted reason and recommendation. Mark one implicit warrant.
Compare argumentation and argument from ignorance. Explain why absence of disproof establishes neither effectiveness nor ineffectiveness.
Write a qualified recommendation, a possible exception and a testable next investigative step.

Source examination

Open at least one complete Atlas profile and select a reference listed there. Record title, locator where available and documented scope. Separate your inference from what the reference actually supports. A reference alone does not establish every statement in a profile.

Station 1 · AT-CORE-238-032

Argumentation

The linking of claims and reasons in pursuit of justified assent.

Formulate a claim and the reason why someone should accept it. Record the two separately.

What exactly is being justified, and on what grounds?

Read the definition and distinctions in the linked full profile. Which statement is supported by its documented reference, and which arises only from your comparison with the exercise?

Toulmin model of argument

The Toulmin model distinguishes data, claim, warrant, backing, qualifier and conditions of exception within an argument.

Examine the move from data to claim. The model helps frame questions without deciding the answer in advance.

Which warrant remains implicit in a short newspaper argument?

Station 3 · AT-ADD-20261016-0003

Argument from ignorance

An argument from ignorance takes the absence of disproof or confirmation as support for declaring a claim true or false.

Examine the treatment of missing knowledge. Uncertainty and refutation are different states.

How can a statement be rewritten if it infers certainty from the absence of disproof?

Evidence

The degree to which a claim is supported by proof or compelling grounds.

Return to the source and note which part of the claim it actually supports.

Which alternative explanation also fits the available data?

Discussion guidance – not a single prescribed answer

Temporal succession does not establish causation. Improvement might involve more study time; that alternative also remains a hypothesis.
The ignorance-argument diagnosis concerns the move from missing disproof to certainty, not a final judgement about the app.
In the Toulmin model, distinguish data, claim and warrant. Qualification is a refinement, not an automatic admission of falsity.

Feedback rubric

0–2 points: distinguish concepts and analytical levels accurately.
0–2 points: connect an inference to specific evidence and its limit.
0–2 points: examine an alternative interpretation or counterexample transparently.

A feedback guide, not a standardized or empirically validated assessment. Reasoned alternatives are acceptable.

Research and seminar questions

Which assumption connects your evidence to your claim?
Is the absence of a counterargument already positive evidence?
Which objection changes the strength of your judgement, and which changes its content?

Boundary of this exhibition

These working questions are exercises. They are not experimental findings and do not replace specialist assessment of a particular dispute.
