Who is this critical thinking course for, and who is it not for?

It is for anyone whose work involves deciding on the basis of information: managers approving proposals, analysts reading reports, buyers comparing suppliers, HR staff weighing evidence and anyone who uses AI research or summaries in their job. It also helps team leaders who review other people's AI-assisted work.

It is not a philosophy or formal logic course, not a degree and not a job guarantee. You will not study symbolic logic or academic argument theory. The goal is practical critical thinking skills you use on a real report, chart or AI answer the same day.

What will I learn in the critical thinking course?

Six modules, each finishing with a judgement you write down and can defend.

1. Checking what AI tells you

Tracing a claim back to a primary source, and spotting invented facts, quotes and references. Even model makers say their techniques reduce hallucinations without removing them.

2. What sits behind an AI answer

Training data, retrieval and model limits explained plainly, so you know when an answer is likely to be out of date or guessed.

3. Evaluating sources

Judging a source's authority, date, purpose and bias, and telling a primary source from a summary of a summary.

4. Weak arguments and misleading numbers

Common fallacies such as false cause and cherry-picking, plus percentages without a base, averages that hide spread and charts with a cut axis.

5. Bias, including automation bias

Confirmation bias, and automation bias: the pull to accept an answer because a system produced it confidently. You practise habits that counter both.

6. Deciding and explaining

Using AI as an adviser for options and counter-arguments without handing over the decision, asking questions that expose assumptions and writing a short decision note others can check.

Do I need experience to build critical thinking skills here?

No. There are no prerequisites and no coding. It helps if you have used at least one AI assistant, but the first module shows you how. Some tasks involve simple percentages and averages; nothing goes beyond arithmetic you would do in a spreadsheet.

How does the personalised path adapt to me?

The diagnostic gives you a short AI-written market summary containing one invented statistic, one misleading chart description and one sound point. What you catch decides where you start. Someone who misses the statistic begins with checking AI output; someone who catches everything goes straight to bias and decisions.

Examples follow your role: a buyer weighs two supplier claims, a marketer reads a campaign report, a manager judges a business case.

What do I practise?

One example from module four: Saltmarsh Foods, a fictional food distributor, receives a proposal saying a new delivery app cut late deliveries by 40 per cent at another firm. You list the questions you would ask before believing it, and say what evidence would change your mind.

The rubric is shown first. It checks that you asked for the base numbers behind the percentage, that you questioned whether the other firm is comparable, that you named at least one other cause for the change, and that your conclusion is proportionate to the evidence rather than a flat yes or no.

How long does the critical thinking course take?

Each lesson takes 10 to 15 minutes. Your path is shaped by the diagnostic and moves at your pace, so we do not quote a total number of hours.

What do I get at the end?

A final practical assessment: you review a realistic AI-assisted report and write a decision note. Passing earns a recognised certificate. It is not an accredited qualification.
