Transparency & Framework

Methodology & Limitations

This platform was built as a training and self-reflection tool, not as a research instrument. To be transparent about that, here is exactly how the challenges are constructed and where their limits lie.

How the Challenges Are Constructed

✓ Every subcategory is built around one clear estimation task — no ambiguity about what is being asked.
✓ Difficulty rises gradually across 10 levels (5 for the reaction test, 9 for grid memory).
✓ Each level introduces a small, controlled change — smaller tolerances, shorter timers, or more similar distractors.
✓ This means your score reflects your underlying calibration, not random chance or guessing.
✓ Units are deliberately mixed across levels — grams vs kilograms, seconds vs milliseconds, degrees vs percentages — to test whether your intuition adapts to context.

How Scoring Works

Two Formulas

📊 Relative Error Formula

Used for measurable quantities like weight, force, angle, duration and count. Score = 100 minus the percentage error between your answer and the true value.

🎯 Proximity Formula

Used for memory, position and reaction tasks. The closer your selection or click, the higher the score.

Both formulas output a standardized score from 0 to 100.

Subcategory and Overall Scores

● A subcategory average of 75 or higher unlocks its mastery badge and lights it up green in the challenge selector.

● Your overall Intuition Score is the mean of your five category averages, expressed out of 100.

● As you play more levels, your score becomes more stable and more representative of your real calibration.

Limitations

⚠️ Not Psychometrically Validated: The tests have no published norms, no reliability coefficients, and no peer-reviewed validation studies.

📱 Device-Dependent: Scores are not comparable across devices. Screen size, touch latency, and hardware performance affect reaction and timing tasks.

☕ Daily Variations: Nothing is standardized across sessions. Day-to-day variability in attention, sleep, caffeine, and mood affects scores more than most people expect.

🎯 Pure Estimation: The tests measure estimation, not general intelligence, personality, or any clinical trait.

🚫 Non-Diagnostic: Scores do not indicate any medical, psychological, or professional characteristic and should not be used for assessment of any kind.

What the Tests Are Useful For

📌 Personal Benchmarking Seeing where your intuition is naturally calibrated and where it systematically drifts.

📈 Tracking Improvement Many users report that after a week of play, time and quantity estimation scores noticeably improve.

🪞 Self-Reflection Understanding your estimation biases helps you know when to trust your gut vs calculate.

📅 Daily Calibration The daily challenge is a short, structured way to check in with your intuitive accuracy.

If you are looking for validated cognitive assessments, consult a licensed psychologist. This platform is a training tool, not a diagnostic one.
