Diploma in Critical Thinking
Course Overview
The Diploma in Critical Thinking at the London School of Journalism, Humanities & Modern Languages (LSJHML) is a nine-to-twelve-month UK qualification for policy researchers, editorial assistants, junior consultants and career-changers who need a structured discipline in reading arguments, weighing evidence and writing analytical work that holds up to scrutiny. You will work through formal and informal logic, the analysis of statistical and empirical claims, the rhetoric of contemporary public debate, and the construction of your own arguments under tutor supervision.
The Diploma in Critical Thinking is built for people who already use reasoning at work and want to do it better. Editorial researchers learn to spot motivated argumentation; policy juniors learn to interrogate a claim's evidence base; strategy consultants learn to write a memo that does not collapse the first time a partner reads it.
Key Features
- Formal and informal logic foundations — argument structure, validity, common fallacies, soundness vs. cogency.
- Evidence appraisal module — reading studies critically, base rates, correlation vs. causation, the limits of inference.
- Statistical literacy strand — graph reading, descriptive statistics, common pitfalls in survey and polling claims.
- Applied reasoning workshops — current debates in policy, ethics, business strategy and media analysis.
- Argumentative writing project — produce a 3,000-word analytical paper on a current debate, supervised across the year.
- Three study modes — on-campus seminars in central London, online with cohort calls, or distance learning with structured deadlines.
What You Will Learn
The Diploma in Critical Thinking is structured around four strands — formal reasoning, evidence appraisal, applied reasoning and argumentative writing. You graduate able to break down a complex argument into its components, identify what evidence the argument actually rests on, and write an analytical paper that holds an opposing reader's attention.
- Argument structure — premises, conclusions, inference, the standard form.
- Formal logic — propositional and basic predicate logic, validity, common forms.
- Informal logic — fallacies, ambiguity, equivocation, motivated reasoning.
- Evidence appraisal — study design literacy, sample issues, replication and the credibility crisis.
- Statistical literacy — descriptive statistics, polling, graph honesty, base-rate neglect.
- Rhetorical analysis — framing, agenda-setting, prebunking, narrative manipulation.
- Argument mapping — visualising arguments, identifying load-bearing claims.
- Argumentative writing — structure, the strongest opposing view, the burden of proof, voice.
- Applied case studies — climate, public health, economic policy, media narratives.
Who This Diploma Is For
- Editorial researchers, fact-checkers and junior journalists wanting a structured analytical discipline alongside their reporting skills.
- Policy juniors, civil servants and parliamentary staff seeking a credible reasoning foundation.
- Junior consultants and analysts in strategy, public-affairs or research consultancies.
- Career-changers from teaching, the law or technical fields moving into analytical and editorial work.
Career Pathways
Critical thinking rarely names itself in a job advert, but it underpins much editorial, policy and consulting work in the UK. Diploma graduates typically use the credential to support a move into research, analytical or editorial roles. Typical destinations include:
- Policy Analyst (think tank, parliamentary unit, devolved government)
- Strategy Consultant (small or mid-tier consultancy, in-house strategy team)
- Editorial Reviewer (longform magazine, fact-checking unit, editorial standards team)
- Research Associate (think tank, university research project)
- Education Consultant (curriculum design, teacher training)
- Senior Editorial Researcher (broadcaster, longform podcast, opinion section)
The Diploma is the natural prerequisite for the Advanced Diploma in Critical Thinking and pairs well with BA progression in Philosophy, Politics or Journalism.

- IELTS 5.5 overall (no band below 5.0) for non-native English speakers.
- Personal statement.
