"Intelligence is not fixed—it's a skill we can measure and improve."
Pioneered the fluid intelligence assessment methodology that forms the core of our multi-dimensional testing approach.
How four specialists revolutionized intelligence testing by combining their expertise to create the most comprehensive cognitive assessment ever developed
For decades, intelligence testing has been limited by a fundamental flaw: traditional IQ tests measure only a narrow slice of human cognitive ability. They focus primarily on logical reasoning and pattern recognition, completely ignoring other critical dimensions of intelligence.
Only measures logical-mathematical intelligence, ignoring other cognitive strengths
Traditional tests take 2-3 hours, making them impractical for most people
Professional IQ testing costs $200-500, putting it out of reach for many
In 2019, four leading cognitive scientists came together with a revolutionary idea: what if we could measure intelligence across multiple dimensions, not just one? What if we could create a test that was faster, more accurate, and more comprehensive than anything that came before?
Fluid intelligence and pattern recognition assessment methodology
Working memory and processing speed measurement
Statistical validation and cultural fairness assurance
Continuous accuracy improvement through adaptive algorithms
By combining these four areas of expertise, we created an assessment that measures logical reasoning, working memory, processing speed, spatial reasoning, verbal comprehension, and cognitive flexibility - all in just 3 minutes.
Our AI analyzes your responses in real-time and selects questions that precisely match your cognitive level
Each question measures a specific cognitive domain - from pattern recognition to spatial awareness
Your results are analyzed across all cognitive dimensions to provide a complete intelligence profile
