Hallucination, Error, and Uncertainty


Learn to separate fluent presentation from reliable knowledge by identifying fabrication, factual error, unsupported claims, material omissions, contextual mismatch, invalid inference, false precision, and unresolved uncertainty.

Unit overview

Unit 10 begins the course's focused study of epistemic responsibility. Generative AI may produce coherent content that includes invented details, incorrect claims, unsupported conclusions, missing qualifications, contextually unsuitable advice, invalid reasoning, or unjustified precision. You will learn to divide an output into verifiable claims, classify different forms of error and uncertainty, consider possible consequences, and apply the author-approved TRACE framework to document findings, corrections, escalation, and stopping.

Identify the claim

Separate factual claims, interpretations, recommendations, calculations, citations, and uncertainty statements.

Classify the problem

Distinguish fabrication, factual error, unsupported claim, omission, mismatch, invalid inference, and false precision.

Correct responsibly

Determine required evidence, assess consequences, document corrections, preserve uncertainty, and stop when verification is inadequate.

Central idea: A polished response should be treated as a set of provisional claims, not as established knowledge. Verification effort should increase with consequence, uncertainty, novelty, and the difficulty of correction.

Unit learning outcomes

By the end of Unit 10, you should be able to:

  1. Distinguish hallucination, fabrication, factual error, unsupported claim, material omission, contextual mismatch, invalid inference, and false precision.
  2. Separate an AI-generated passage into independently assessable claims.
  3. Distinguish facts, interpretations, recommendations, predictions, calculations, citations, and uncertainty statements.
  4. Explain why fluency, confidence, detail, formatting, and citations do not establish reliability.
  5. Identify internal inconsistencies, unverifiable specifics, inappropriate certainty, and missing qualifications.
  6. Assess the possible consequence, reversibility, and verification burden associated with an error.
  7. Determine what kind of evidence or qualified review each claim requires.
  8. Distinguish correction from concealment, paraphrase, or unsupported replacement.
  9. Preserve justified uncertainty rather than forcing an unsupported answer.
  10. Apply the author-approved TRACE framework to a bounded output or workflow.
  11. Define escalation and stop conditions when verification is unavailable or consequences are unacceptable.
  12. Begin Assignment 5 and extend Assignment 1 with evidence from Unit 10.

Unit 10 lessons

Complete the five lessons in order. The filenames are local to the dedicated Unit 10 folder.

Lesson 1 of 5 · 70–85 minutes

10.1 Hallucination and Error Types

Distinguish fabrication, factual error, unsupported claims, omissions, contextual mismatch, invalid inference, and false precision.

Lesson 2 of 5 · 70–85 minutes

10.2 Claim Identification and Decomposition

Break fluent passages into factual claims, interpretations, recommendations, calculations, citations, and uncertainty statements.

Lesson 3 of 5 · 70–85 minutes

10.3 Credibility Cues and False Confidence

Examine how tone, detail, structure, technical language, numbers, quotations, and references can create unwarranted confidence.

Lesson 4 of 5 · 75–90 minutes

10.4 Consequence, Correction, and Uncertainty

Prioritize verification by consequence, identify appropriate corrections, preserve uncertainty, and design escalation or stopping.

Lesson 5 of 5 · 90–120 minutes

10.5 TRACE Error and Uncertainty Audit

Apply TRACE to a complete output, document evidence needs and corrections, and create the initial record for Assignment 5.

Folder convention: Keep unit-10.html and t-01.html through t-05.html in the same dedicated Unit 10 Moodle folder.

Assignment 1: Journal continues

Reflect on confidence, credibility cues, error types, verification burden, correction, uncertainty, and how TRACE changed your evaluation of AI output.

Recommended final submission: End of Module 6, Week 11.

Participation options

Option A: Approved AI

Generate or compare bounded, low-risk outputs using synthetic, public, supplied, or authorized information.

Option B: Supplied outputs

Use supplied passages, claims, citations, calculations, annotations, and correction records.

Option C: Non-AI analysis

Complete the same claim decomposition, error classification, consequence, and TRACE analysis without an AI platform.

Responsible-use boundaries and support

Boundaries

  • Do not use health, legal, financial, safety, employment, disciplinary, or other high-consequence claims for live experimentation.
  • Do not upload confidential, personal, proprietary, privileged, unpublished, or culturally governed information.
  • Do not treat generated citations, quotations, calculations, or source descriptions as authentic until verified.
  • Do not conceal errors by merely rewriting them more fluently.
  • Do not claim certainty beyond the available evidence.

Support and accessibility

  • Use supplied outputs if live AI is inaccessible, unsuitable, or unwanted.
  • Contact the course coordinator for claim-set and assignment questions.
  • Use library services for source planning and verification support.
  • Seek qualified disciplinary or professional review when claims exceed your competence or authority.
