METHODOLOGY
How we score
A short, honest look at where your results come from — and where the limits of precision lie.
Our approach
Every quiz is built on axes — simple measurable spectrums like “inward ↔ outward energy”. Your answers are averaged per axis, and your type is the quadrant closest to you, not a label.
What quizzes can — and can’t — tell you
A short quiz is a snapshot, not a diagnosis. It shows tendencies, not destiny: results change as you do. The Logic Sprint is a warm-up, not a clinical IQ measure; the Stress Thermometer is a self-check, not a medical assessment.
How the percentages work
The percentages in your result are normalized weights of your answers: they always sum to 100% and show the ratio of your tendencies, not an absolute quantity.
The IQ battery: five domains
The battery mirrors the structure of the major validated batteries (the Cattell–Horn–Carroll model, the Wechsler family): fluid reasoning — 3×3 matrices, visuospatial reasoning — three-dimensional rotation, quantitative reasoning — number series, working memory — forward and backward digit sequences, processing speed — timed symbol search. Item formats come from validated instruments (ICAR — Condon & Revelle, 2014; the classic Wechsler-family formats); the items themselves are generated by us and carry no published norms.
How the IQ score is computed
Each subtest maps onto the standard IQ scale (mean 100, SD 15): on six-option items the share of correct answers is first corrected for guessing, in symbol search wrong answers subtract from right ones, and in digit sequences only administered trials count. The combined score is not an average of subtests: the sum of z-scores is re-standardized with their intercorrelations taken into account (r̄ = 0.5), the way full-scale scores of the major batteries relate to their subtests. Every score ships with a ± band — the precision limit set by test length. Population parameters are provisional a-priori values: until real completions accumulate the estimate is approximate, carries no percentiles, and is not a clinical measurement.
