Brainstorming versus factual research: when AI is the right tool

AI is a superb tool for generating, drafting, structuring and explaining. It is the final authority for nothing. Learn to sort your tasks into the two piles before you start, and the checking takes care of itself.

In this lesson you will

  • Sort a task into "AI is the right tool" or "AI is a starting point that must be checked"
  • Write brainstorm prompts that keep the model away from factual claims
  • Say clearly what AI is never the final authority on

Most of the frustration with AI comes from using it for the wrong pile of tasks. Ask it for twenty ideas and it is brilliant. Ask it for the one true fact and it is a gamble. The tool did not change between those two requests; the job did. Sorting jobs before you start is the single habit that removes most of the risk.

Two piles. The left column needs no checking because there is nothing to be wrong about; the right column is always checked.
AI is the right tool (generate, shape, explain)AI is a starting point only (facts about the world)
Brainstorming ideas, names, anglesPrices, limits and plan details
Drafting from your own notes and factsLaws, rules, deadlines and eligibility
Rewriting for tone, length or audienceMedical, financial or legal specifics
Explaining a settled conceptAnything about a real person
Structuring: outlines, tables, checklistsQuotes, citations and references
Practising: quizzes, role-play, language drillsRecent events and anything that changed this year

Keep the brainstorm out of the fact pile

A brainstorm goes wrong when the model slips facts into it — a product that does not exist, a statistic to make an idea sound better. You can tell it not to.

Your turn

A brainstorm that stays a brainstorm

Give me [NUMBER] ideas for [TASK]. One line each, numbered. Do not include any statistics, prices, product names or claims about real companies or people — ideas only. If an idea needs a fact to work, write "(needs checking: …)" after it.

Hint: The last sentence is the useful one: it makes the model label the ideas that would need lesson 4's check.

The final authority for nothing

This is the sentence to keep: AI is the final authority for nothing. Not because it is usually wrong — it is usually right — but because it has no way of knowing when it is not, and neither do you from the text alone. For anything that matters, the last step is a source that is not a model: the vendor's page, the statute, the document, the person. AI gets you to that step faster. It does not replace it.

Lesson FAQ

Is AI good for research?

It is good for the first hour of research — explaining the area, listing the questions, naming where the answers live. It is not good as the answer, because it cannot tell you when it is wrong. Use it to get to the sources faster, then read the sources.

What should I never rely on AI for?

Anything where being wrong has a cost you cannot undo: medical, legal and financial specifics, quotes attributed to real people, and deadlines. Use it to prepare your questions for a qualified person, not to replace them.

Can I use AI for brainstorming without checking anything?

Yes, as long as the output is ideas rather than claims. Tell it to leave out statistics, prices and real names, and to flag any idea that depends on a fact. The ideas are yours to judge; only the facts need checking.
