What AI Can and Cannot Do – A Practical Guide

Lesson 5: Choosing When to Use AI and When Not To

Lesson Objectives

By the end of this lesson, students should be able to:

  • Apply the four-question AI decision framework to any task
  • Distinguish between tasks where AI is the right tool and tasks where it is not
  • Explain their decision reasoning to a colleague
  • Build a personal "AI use map" for their most common professional tasks

Lesson Content

The core decision framework – four questions.

Question 1: Is this task language-intensive? AI's strengths are primarily language-based – writing, synthesis, explanation, code. If the task is primarily about judgment, physical action, interpersonal relationship, or real-time data, AI adds less value. If it is primarily language-based, proceed to question 2.

Question 2: Does this task require current or highly specific factual information? If yes – current events, live data, highly specific technical specifications, regulatory details – the answer is either (a) supplement AI output with verified current sources, or (b) do not use AI for the factual core of this task. AI handles well-established, general information reliably; specific and current information requires verification.

Question 3: How severe are the consequences of an error? Low-severity, easily-correctable tasks (internal drafts, brainstorming, first outlines) tolerate AI's error rate well. High-severity tasks (legal filings, medical guidance, financial disclosures, safety protocols) require more stringent verification or human expert input, even if AI is involved in drafting.

Question 4: Does this task require a judgment call that belongs to a human professional? If the task output is a professional recommendation, advice, or decision that carries accountability – and where your expertise is what the client, employer, or audience is paying for – AI is an input tool, not a decision maker. Human professional judgment is the required output.

Quick reference: high-value AI use.

  • High-value: Language-intensive, general information, low-severity, routine – drafts, summaries, explanations, code templates, brainstorming.

Quick reference: use with caution.

  • Use with caution: Language-intensive, specific/current information, medium severity, some professional judgment needed – research synthesis with verification, analytical drafts with expert review.

Quick reference: exclude or use minimally.

  • Exclude or minimal: Non-language primary, high-severity, clear professional judgment required, current information critical – medical advice, legal conclusions, safety-critical specifications, real-time data-dependent decisions.
