Riot IQ
Professional online IQ test based on scientific intelligence research
What is Riot IQ? Complete Overview
The Reasoning and Intelligence Online Test (RIOT) is the first professional online IQ test built on over a century of intelligence research. Developed by IQ researcher Dr. Russell T. Warne, RIOT adheres to strict psychometric standards set by the APA, AERA, and NCME. This scientifically validated assessment measures six cognitive abilities through 15 subtests, providing comprehensive intelligence measurement for adults (18+). RIOT serves as an online alternative to gold-standard IQ tests like WAIS and Stanford-Binet, with norming based on a diverse U.S. population sample. The platform serves psychologists, researchers, clinicians, employers, institutions, and curious individuals seeking accurate cognitive assessment.

What Can Riot IQ Do? Key Features
CHC Model-Based Assessment
RIOT is built on the Cattell-Horn-Carroll (CHC) model of intelligence, one of cognitive psychology's most widely recognized frameworks. This scientifically validated model categorizes intelligence into broad abilities that RIOT measures through its 15 subtests, ensuring comprehensive cognitive assessment aligned with modern intelligence theory.
Professional Standard Compliance
RIOT meets all educational and psychological testing standards set by the American Educational Research Association, American Psychological Association, and National Council on Measurement in Education. This makes it the only online intelligence test with full professional validation comparable to clinical assessments.
Bias Reduction Process
Every RIOT question undergoes rigorous sensitivity review by a diverse panel of experts to identify and remove potentially biased content. Statistical analyses further ensure fairness across demographics, making RIOT one of the most equitable intelligence assessments available online.
Comprehensive Cognitive Profile
RIOT provides detailed analysis of six cognitive abilities (Verbal Reasoning, Fluid Reasoning, Spatial Ability, Working Memory, Processing Speed, and Reaction Time) through 15 subtests. Results include 16 T-scores for granular performance analysis across all measured dimensions.
Researcher Tools
RIOT offers a free administration platform for professionals to conduct studies, with four test versions available (Sample, Basic, Full, and Custom). This makes it valuable for psychologists, researchers and institutions needing reliable cognitive assessment tools.
