HOW THE INTELLESTIS IQ TEST WAS DEVELOPED
The Intellestis IQ Test was developed in collaboration with Dr. Arvesa Studenica (PhD in Cognitive Psychology) and is grounded in established psychometric research traditions. Our goal was to design a short, engaging, and fair measure of reasoning ability that reflects key principles of modern intelligence testing.
Our Foundation
- The test follows the Cattell-Horn-Carroll (CHC) framework, focusing on fluid intelligence (Gf) — the ability to reason, solve novel problems, and identify patterns without relying on prior knowledge.
- Item design draws on proven formats from widely recognized reasoning assessments, such as Raven-style abstract matrices, 3D mental rotation tasks, and non-verbal number/logic sequences .
- Verbal content has been minimized to reduce the influence of language skills or cultural background, ensuring fairness across diverse test-takers.
Important Disclaimer:
The Intellestis IQ Score is a proprietary simulated result based on performance in logic and visual reasoning challenges. It is intended for self-reflection and entertainment purposes only, and does not represent a clinically validated IQ measurement.
Item Families
The Intellestis IQ Test consists of 25 items across several reasoning domains:
- Abstract/Matrix Logic – visual pattern recognition and rule-based problem solving.
- 3D Spatial Rotation – mental manipulation of objects in three-dimensional space.
- Number Series – identification of numerical rules and sequences.
- Logical Deduction – rule-based reasoning with minimal text load.
Each family uses a single rule system with a clear progression from easier to more complex items. Distractor options are carefully constructed “near misses” that each break only one rule, ensuring a single correct solution and psychometric clarity
Test Design Principles
- Fairness & Accessibility – minimal language requirements, culture-free visuals, and consistent formatting.
- Difficulty Gradient – a smooth progression from onboarding items to advanced challenges that distinguish top performers.
- Standardization – uniform visual grammar (line weight, layout, colors) to reduce unnecessary cognitive load and keep the focus on reasoning skills.
- Timing – items are optimized for timed conditions, measuring how effectively participants apply rules rather than re-learn new ones for each item.
Scoring
- Raw scores (0–25) are mapped to a provisional IQ-like scale ranging from 80 to 145 resulting in the Intellestis IQ Score
- This score distribution is designed to reflect standard IQ interpretations (Average = 100, SD = 15), while clearly stated as a simulated, non-clinical score .
- Performance bands range from Low Average through High Average up to Very Superior (see scoring table in our report).
Ongoing Validation
The Intellestis test is undergoing continuous refinement:
- Large-scale pilot studies are planned to evaluate reliability and fairness.
- Advanced psychometric models (e.g., Rasch and 2-Parameter Logistic models) will be applied to calibrate item difficulty and discrimination.
- Future studies will assess convergent validity by comparing Intellestis results with established non-verbal IQ measures .
