Cognitive Reflection Test – CRT-7 Assessment

The Cognitive Reflection Test (CRT-7) measures how often you pause an intuitive impulse and apply deliberate reasoning. Each item challenges quick but misleading answers.

The tool presents seven classic riddles through a reactive interface. You pick one option per question, track progress, and receive a concise score with an interactive donut chart summary.

Use this screen to gauge decision habits before exams, interviews, or strategy sessions. *Do not treat the result as an IQ substitute.* Results do not constitute a clinical diagnosis.

Technical Details:

The assessment runs entirely in the browser using a lightweight client framework and a charting layer. State updates render instantly without page reloads, and no responses leave your device.

Adaptive Navigation

The interface jumps to the next unanswered item when you select a choice, keeping momentum high. Example: choose “5 cents”, and the list scrolls forward. Caution: mis-clicks advance automatically; use the sidebar to return.

Instant Scoring

The score badge recalculates every time the final answer lands, classifying performance into four level bands. Example: four correct answers show “4 / 7 · High”. Caution: partial results remain hidden until all items are complete.

Interactive Donut Chart

A responsive pie visualises correct versus incorrect counts and resizes on window changes. Example: resize the browser; the chart scales smoothly. Caution: disable animations on low-power devices for battery savings.

Client-Side Privacy

All logic executes locally and never transmits data. Example: reload the tab—answers vanish because nothing was stored. Caution: closing the tab deletes unfinished progress.

Accessibility Aids

ARIA labels, keyboard focus states, and readable colour contrasts support diverse users. Example: press Tab to cycle radio buttons. Caution: screen readers may mispronounce mathematical symbols; enable verbose mode if available.

Calculations & Scoring:

The tool counts correct selections and maps the total to a performance level.

Formula

score = Σ(correct answers)

Example

If you answer items 1, 3, 4, 6 correctly, score = 4.

Interpretation

All answers stay in your browser; no personal data is stored or transmitted.

FAQ:

Troubleshooting:

• Interface not loading – disable tracker blockers and reload.
• Chart missing – ensure JavaScript is enabled.
• Keyboard focus lost – press Tab twice to reset outline.
• Unexpected scroll – check mouse-wheel sensitivity settings.
• Badge colours look dull – switch to high-contrast mode in your OS.

Advanced Tips:

• Read each question aloud to slow intuitive bias.
• Time yourself; slower deliberate pacing often yields more correct answers.
• Attempt the quiz after mental tasks to observe fatigue effects.
• Compare scores over weeks to track reasoning improvement.
• Discuss tricky items with peers to reveal hidden assumptions.
