The Cognitive Reflection Test (CRT-3) gauges how readily you override fast, intuitive answers with slower, analytical thinking. Each question looks deceptively simple yet reveals the balance between gut reactions and deliberate reasoning.

Across three classic brain-teaser scenarios, you choose one option from four plausible values. Correct selections indicate reflective processing; intuitive traps signal reliance on first impressions. Your combined score classifies reflective ability on a four-level scale.

Use this quick self-check during study sessions or workshops to spotlight reasoning habits and track progress over time. Avoid treating the result as an IQ measure. **Results do not constitute a clinical diagnosis.**

Technical Details:

The assessment converts each response into a binary correctness vector, sums the vector for a raw score (0-3) and maps that score to a qualitative band.

The underlying concept—cognitive reflection—captures the mental pause where analysis supplants intuition. The algorithm therefore rewards accurate overrides rather than response speed.

  • Three independent multiple-choice items.
  • Binary marking: 1 = correct, 0 = incorrect.
  • Raw score Σci where c∈{0,1}.
  • Band lookup assigns Low to Very High.

Calculations & Scoring:

The following explains exactly how your raw score and performance band are derived.

Sum of correct responses.

(c1,c2,c3)=(1,0,1)
— Answers convert to binary values for summation.

S=1+0+1
S=2 The vector sum yields your raw score.

S=2
— Store the total for band assignment.

Your raw CRT-3 score equals S = 2.

Piecewise mapping from score to band.

S=2
— Begin with the calculated total.

2 → High
— Lookup table returns the band.

L=High
— Present the qualitative result.

Your performance band is High.

Step-by-Step Guide:

Follow these steps to complete the assessment smoothly.

  1. Click the Begin Test button to reveal the first question.
  2. Read the scenario and options carefully before choosing an answer.
  3. Select your initial instinct; the progress bar updates instantly.
  4. Reflect briefly and change the selection if deeper reasoning suggests another choice.
  5. Use the side list to revisit any item; answered rows show a check-mark icon.
  6. After all three items are answered, review your score, band badge and donut chart.

FAQ:

Common questions about the CRT-3 assessment are answered below.

What does the score show?

The raw score counts how many intuitive traps you avoided. Higher numbers suggest stronger reflective control in concise problem-solving situations.

Is my data stored?

No. All answers remain in your browser’s memory and optional URL code. Nothing transmits to servers or analytics services.

Can I retake the test?

Yes. Refresh the page or clear the URL parameter to reset responses and attempt the questions again.

Does speed affect results?

Timing is not measured. Only accuracy matters, allowing you to focus on the balance between instinct and analysis.

Is this an IQ examination?

No. The CRT-3 targets a specific reasoning facet and should not replace formal intelligence or aptitude evaluations.

Troubleshooting:

Resolve common issues quickly with the suggestions below.

Progress bar stays at 0 %.
Select an option for each question; unanswered items prevent progression.
Chart not visible.
Resize the window or rotate your device; the charting layer re-flows automatically.
URL code looks odd.
Only digits and dashes are valid. Delete extra characters and reload.
Accessibility reader skips content.
Enable semantic-mode in your reader or copy results to plain text for narration.

Advanced Tips:

Enhance your insights with these expert suggestions.

  • Time each attempt informally to observe instinct-to-reflection latency.
  • Discuss reasoning paths with peers to uncover hidden heuristics.
  • Log results over weeks to monitor improvements in analytical override.
  • Attempt variant questions to generalise reflective habits.
  • Use private-browsing mode when demonstrating to students to avoid cached answers.
