Red Flags to Watch For

The limits that matter most.

What you'll leave with

By the end of this lesson, you'll understand clearly which categories of decision should always involve human judgment and qualified professionals — and why this is wisdom, not timidity.

Why this matters

This lesson is not about fear. It is about the difference between using AI as a tool and mistaking it for an authority.

AI can help you understand a medical situation. It should not be the source of your treatment decision. AI can help you understand a legal concept. It should not be your lawyer. AI can help you think through a financial question. It should not be your financial advisor.

The distinction is practical, not philosophical.

The idea

There are specific categories where AI's characteristic failure mode — confident fluency with possible inaccuracy — is genuinely dangerous. In these categories, being wrong has real consequences that are difficult or impossible to reverse.

This is not about whether AI is smart. It is about stakes and accountability. A qualified professional carries accountability for their advice. AI does not. When something goes wrong, there is a person responsible for a doctor's recommendation. There is no equivalent accountability in an AI output.

The teaching block

Decisions that always need human judgment and qualified advice:

• Medical decisions: diagnoses, treatment options, medication choices, dosage changes
• Legal decisions: contracts you are about to sign, rights you may be waiving, legal disputes
• Financial decisions: investment choices, significant purchases, retirement planning, debt management
• Safety decisions: anything involving physical risk to yourself or others
• Mental health: AI can provide general information but is not a substitute for care or crisis support

What AI can appropriately help with in these domains:

• Understanding language and terms before a professional appointment
• Preparing questions to ask your doctor, lawyer, or advisor
• Getting a general orientation to a topic so the conversation with a professional is more productive
• Processing information after a professional consultation to make sure you understood it

The practical version of this: use AI to understand. Use qualified humans to decide.

AI asking you clarifying questions, generating options, or explaining concepts does not make it qualified to advise you on a high-stakes decision. Fluency is not expertise. Confidence is not accuracy.

The difference is not in the topic — it is in what you are asking AI to do with the topic.

Try this now

Think of the last time you asked AI (or might ask AI) a question in one of the high-stakes categories above. Was the question in the "understand" category or the "decide" category?

If you are not sure, that uncertainty is itself useful information. When you are unsure which side of the line a question falls on, that is a signal to involve a professional.

Quiet takeaway

Module 5 complete. You now have calibrated judgment about when to trust AI, when to check it, and when to go to a human instead. That judgment is what separates thoughtful AI use from reckless AI use.
