Common myths about IQ
- IQ is not fixed for life — reasoning skills grow with practice and learning.
- One test is a snapshot, not a verdict on your cognitive ability.
- A high score doesn't guarantee success. Effort, environment and curiosity matter at least as much.
What this test measures
Fluid reasoning across five domains:
- Pattern recognition. Spotting the visual rule in shape grids and sequences.
- Numerical reasoning. Inferring the rule behind a number sequence.
- Logic & deduction. Drawing valid conclusions from given premises.
- Verbal reasoning. Mapping relationships between words and concepts.
- Spatial reasoning. Mentally rotating, folding and mirroring shapes.
How scoring works
We sum correctly answered questions, weighted by difficulty (easy ×1, medium ×1.5, hard ×2). That raw total is mapped to an IQ-style scale with mean 100 and standard deviation 15. Your percentile is derived from a normal distribution at that score.
This is an estimate calibrated to question difficulty, not a clinical norm-referenced score.
