## What is Ockham?

**HOW TO THINK. NOT WHAT TO THINK.**

Every day, we make judgements about what to believe, whom to trust and which decisions to make. But how good are we at separating evidence from assumption, recognising weak arguments and knowing when to change our minds?

Ockham helps you find out.

Unlike conventional IQ tests and brain-training games, Ockham focuses on critical thinking: how you evaluate information, question assumptions, draw conclusions and make judgements when the answer isn't obvious.

**DISCOVER HOW WELL YOU THINK**

Start with a free 12-question assessment covering six critical-thinking skills. Receive your Critical Thinking Score, explore your answers and understand the reasoning behind every question.

No registration. No subscription. No time pressure.

**SIX SKILLS THAT MATTER**

• Evidence Evaluation — distinguish credible evidence from unsupported claims.

• Argument Analysis — recognise strong arguments and identify weak ones.

• Inference and Deduction — draw conclusions that follow from the facts.

• Bias and Flawed Reasoning — identify assumptions, biases and misleading arguments.

• Quantitative Judgement — interpret numbers and comparisons accurately.

• Decisions Under Uncertainty — make considered judgements when information is incomplete.

**GO BEYOND YOUR FIRST ASSESSMENT**

Unlock Standard (24 questions) and Deep (48 questions) assessments to explore your reasoning in greater depth.

Encounter different questions, track your progress over time, revisit previous results and learn from detailed explanations.

**ONE PURCHASE. LIFETIME ACCESS.**

Your first Quick Assessment, complete score and every answer explanation are free.

For those who want to go further, a single in-app purchase unlocks repeat assessments, deeper testing, full history and PDF summaries.

No recurring fees. No advertising. No compulsory account.

**BETTER THINKING BEGINS WITH BETTER QUESTIONS.**

Question assumptions. Follow the evidence. Remain intellectually open without being gullible.

Ockham doesn't tell you what to think. It helps you examine how you think.
