The Cognitive Reflection Test (CRT) challenges you to replace an instinctive but incorrect answer with deliberate reasoning. It illustrates how often your quick intuition yields to slower, analytical thought when confronting deceptively simple numerical or logical riddles that disguise surprising answers through minimal context and everyday wording, revealing your cognitive style.
This interactive page presents the three-item CRT in a streamlined format. You answer each question, watch the progress bar grow, and immediately receive a donut-chart breakdown of correct versus incorrect responses alongside tailored feedback. All processing occurs locally, so no answers leave your browser, ensuring privacy while delivering instant, visually clear results.
Apply this concise screen whenever you need a quick, private snapshot of how readily you reconsider intuitive answers during budgeting, planning, or troubleshooting sessions; avoid treating the score as professional advice, and remember results do not constitute a clinical diagnosis or substitute for comprehensive cognitive evaluation or professional guidance from qualified specialists.
Technical Details:
A lightweight reactive engine binds form inputs to computed properties. Each selection updates progress indicators and recalculates the score in real time without reloading the page. Upon completion, a compact charting layer renders a donut visualisation using the score array, resizing responsively to any viewport.
All logic, data, and charts run entirely in your browser. The bundle loads one small stylesheet, one script for interaction, and one vector charting asset. Because no network calls occur after initial load, results remain private and performance stays consistent even when offline, enhancing reliability in classroom or workshop settings.
Instant Progress Feedback
The progress bar displays your completion percentage immediately after each answer, helping you pace responses and maintain engagement through visible milestones.
Question Navigation List
A scrollable question list highlights the current item and marks answered ones with a check icon, letting you review or change choices in any order.
Local Score Calculation
The calculation engine tallies correct responses client-side, instantly updating your score without server latency or data transmission, protecting privacy while speeding feedback.
Responsive Donut Chart
A responsive donut chart visualises correct versus incorrect proportions, adapting radius and legend placement automatically when you resize the window or rotate devices.
Badge-Based Result Levels
Coloured badge levels translate raw scores into intuitive labels—Low, Medium, High, Very High—making interpretation quick without external guides or lengthy explanation.
Offline Capability
Because all assets cache and run locally, the tool remains fully functional offline, supporting workshops in venues with limited or unstable internet connections.
Calculations & Scoring:
The score equals the number of correct answers out of three. A simple conditional transforms the score into a descriptive level.
Formula
score = Σ(responsei == correcti) for i = 1‒3Example
If you answer two questions correctly, score equals 2; the badge shows “High”.
Interpretation
| Score | Level |
|---|---|
| 0 | Low |
| 1 | Medium |
| 2 | High |
| 3 | Very High |
Data Privacy: all responses remain in the browser; nothing is sent or stored remotely.
Step-by-Step Guide:
Follow these steps to complete the assessment smoothly.
- Click the Begin Test button to start.
- Read the displayed question and select an option using the radio buttons.
- Watch the progress bar update after each selection.
- Use the left-hand questions list to revisit or change answers at any time.
- After answering all items, review the coloured badge and donut chart for your results.
FAQ:
Find quick answers to frequent questions.
Is my data stored?
No. All answers and scores are processed only in your browser and disappear when you close the page.
What does my score mean?
Higher scores suggest you often override intuitive answers with reflective thought. They do not measure intelligence or guarantee better decisions.
Can I retake the test?
Yes. Refresh the page or click Begin Test again; previous responses clear automatically.
Why only three questions?
The original CRT uses three well-validated items that efficiently indicate cognitive reflection without causing fatigue.
Does speed matter?
No time limit exists. Focus on accuracy rather than speed; reflective thinking may take longer than intuitive guesses.
Will the chart work offline?
Yes. The charting asset loads with the page and functions without internet connectivity.
Troubleshooting:
Resolve common issues with the guidance below.
- No content loads – ensure JavaScript is enabled in your browser.
- Progress bar stays at 0 % – answer at least one question to trigger updates.
- Chart does not appear – confirm all three questions are answered; the chart renders only after scoring.
- Badge colours look dull – disable dark-reader extensions that override page styles.
- Scroll jump in question list – use a modern browser; older versions may not support smooth scrolling.
Advanced Tips:
Enhance your practice with these expert suggestions.
- Discuss each problem aloud to slow intuitive guessing.
- After viewing results, re-attempt only missed questions for targeted reflection.
- Pair the test with journaling to note patterns in reasoning errors.
- Compare scores over weeks to observe improvement trends.
- Introduce time boxing to study how pressure affects your responses.
