Ask What Supports the Answer

Critical thinking involves examining the reasons behind a claim, the evidence supporting it and the assumptions connecting the two. It helps you distinguish a convincing explanation from one that simply sounds confident. The purpose is to reach a considered judgement while remaining willing to revise it when better information becomes available.

This matters when information comes from an AI tool as well as from a person. For example, an AI-generated recommendation may appear clear while leaving out an important condition. Asking what evidence supports the recommendation, which assumptions it relies on and what could challenge it creates a more useful basis for evaluation. This course introduces the reasoning habits behind that approach.

Who Will Benefit from This Introduction?

The course may suit students, people starting work, employees reviewing information and anyone interested in more deliberate everyday decision-making. You do not need previous AI or programming experience to enrol. The syllabus focuses on reasoning and evaluation rather than building AI systems or training in a named software product.

If you want to learn critical thinking online free of charge, compare the modules with the situations in which you use information. The AI emphasis is particularly relevant when you want to examine how automated outputs, data and assumptions can influence a judgement. For broader study of workplace responsibilities, you can also explore our management courses and diplomas.

What You Can Develop

Explain the core principles of critical thinking.
Recognise assumptions and evaluate the reasoning behind an argument.
Analyse information with greater attention to evidence and context.
Question potential bias in data, arguments and AI outputs.
Use structured reasoning to support personal, academic and workplace decisions.

For further explanation of the subject, read our guide to critical thinking skills and examples. It provides wider context for the reasoning habits introduced by this course, while this page sets out the specific three-module programme.

Study, Reflect and Complete Your Assignments

Access the learning materials online and choose a study routine that fits your commitments. As you progress, try explaining a claim in your own words, identifying the assumptions behind it and considering what information would change your view. This is a useful way to connect the ideas with information you encounter outside your studies. Complete the course assignments and achieve the required marks, following the instructions provided in the learning platform.

After successfully completing our free course, you may choose to purchase a QLS-endorsed Certificate of Achievement, a CPD-accredited certificate issued by the CPD Standards Office, or both. Each certificate is optional and has its own price; purchasing one does not require you to purchase the other. Free enrolment, access to materials and completion of your learning do not depend on buying a certificate. Check our current certificate options and fees before ordering, as the amount payable depends on your selection, course level, format and delivery option. A course certificate records successful completion; it does not confer a professional licence or an Ofqual-regulated qualification.

By the end of this course, learners will be able to:

Define and explain the principles of critical thinking.
Recognise assumptions, evaluate arguments, and draw logical conclusions.
Analyse information objectively and question biases in decision-making.
Apply critical thinking in personal, academic, and professional contexts.
Develop stronger problem-solving and strategic reasoning skills.

Free Study and Optional Certification

Course Content

Topics Covered in the Course

Three Modules on Reasoning and AI

The syllabus moves from core thinking principles into structured analysis and the questioning of bias. Each module builds on the previous one, connecting clear reasoning with the need to evaluate information thoughtfully.

Module 1: Foundations of Critical Thinking in the Age of AI

Begin with the principles of critical thinking and their relevance when information and recommendations increasingly involve AI. This module establishes a foundation for reasoning, encouraging attention to how a conclusion is reached rather than only whether it appears plausible. You will consider the value of examining claims, distinguishing assumptions from supporting information and approaching an explanation with purposeful questions. The focus is on developing a more deliberate way of thinking that can support later analysis. These foundations provide the context for exploring analytical thinking and AI logic in the next module.

Module 2: Analytical Thinking and AI Logic

Explore the relationship between analytical skills and AI logic, with attention to how structured thinking supports personal decisions and workplace strategies. Breaking an issue into connected parts can make it easier to identify what is known, what is assumed and what still needs investigation. You will consider how the reasoning behind a conclusion affects its usefulness and why an orderly explanation still needs to be examined carefully. The module connects analytical thinking with everyday judgement, helping you approach information systematically without treating an automated recommendation as a decision that no longer needs human consideration.

Module 3: Identifying and Questioning AI Bias

Examine bias in data, arguments and AI, and practise questioning assumptions when forming a conclusion. This module encourages you to consider what information is included, what may be missing and how a particular viewpoint can influence an explanation. Recognising possible bias creates a reason to investigate further, rather than a shortcut to dismissing every result. You will explore how careful questioning can support a more balanced and informed judgement. This final module connects the foundations of reasoning with the practical challenge of evaluating information whose limitations may not be immediately obvious.
