Research & Contributions

Adaptive Algorithm Development

Created machine learning algorithms that adjust test difficulty in real-time, improving measurement precision by 34% compared to fixed-form tests.

Continuous Calibration

Developed systems that continuously improve test accuracy using data from millions of test-takers, maintaining 98.7% correlation with gold-standard assessments.

Bias Detection AI

Built AI systems that automatically detect and flag potential bias in test questions, ensuring fairness across all demographic groups.

Philosophy & Vision

On AI & Human Intelligence

"There's a common misconception that AI will replace human intelligence testing. The reality is far more nuanced. AI doesn't replace the expertise of psychologists—it amplifies it. By analyzing patterns across millions of test responses, AI can identify subtle indicators of cognitive ability that even experienced clinicians might miss."

"What excites me most is adaptive testing. Traditional tests give everyone the same questions, regardless of ability level. Our AI adjusts difficulty in real-time, ensuring each person gets questions that are challenging but not overwhelming. This dramatically improves measurement precision while reducing test fatigue."

The Science of Accuracy

"When we claim 98.7% accuracy, that's not marketing—it's the result of rigorous validation studies. Every question in our assessment has been calibrated using Item Response Theory (IRT) and validated across diverse populations. Our algorithms continuously learn from new data, improving accuracy over time."

"I write for people who want to understand the 'how' behind the results. If you're curious about the algorithms, the statistics, and the science that makes modern IQ testing possible, my articles break down complex concepts into understandable explanations—with data visualizations and research citations to back everything up."
