Yes, absolutely. Our free IQ test is called the Basic RIOT IQ test. It comes with the caveat of a large margin of error. You can read more about our free IQ test here.

Intelligence is the ability to learn, understand, reason, and apply knowledge to solve problems. It includes a range of cognitive abilities such as memory, reasoning, problem-solving, and adapting to new situations.

An IQ (Intelligence Quotient) test is a standardized assessment that measures cognitive abilities relative to others. Scores are calculated by comparing them to a norm sample, with an average set to 100.

An IQ score indicates how your cognitive abilities compare to a norm sample, which is a large group of individuals carefully selected to represent a broader population in terms of characteristics like age, gender, education level, and socioeconomic status. A score of 100 represents the mean performance within that norm sample, meaning it's the average score achieved by this representative group. Consequently, higher or lower scores indicate performance above or below that average performance established by the norm sample.

Intelligence tests vary in the cognitive abilities they measure. However, most tests primarily assess verbal reasoning, visuospatial ability, and short-term memory. The RIOT measures these abilities, as well as processing speed and reaction time.

IQ testing began in 1905 with the Binet-Simon Scale, developed to assess children's intelligence. Since then, tests like the Stanford-Binet and Wechsler scales have evolved to provide more comprehensive assessments.

Alfred Binet and Théodore Simon developed the first practical IQ test in 1905 to identify children who needed special educational assistance.

Modern IQ tests use a deviation IQ system, where an individual's score is based on how their performance compares to that of a large, representative sample. The average IQ is 100 with a standard deviation of 15, meaning most people score between 85 and 115. IQ scores are statistically derived by converting raw test performance into a standardized scale, allowing for meaningful comparisons across populations.

The CHC Theory is a widely accepted model of intelligence that organizes cognitive abilities. The broadest ability, general intelligence, is used in all cognitive tasks. Other broad abilities, such as verbal ability, visuospatial reasoning, and processing speed--are used in many (but not all) cognitive tasks. Finally, the CHC Theory recognizes the existence of narrow abilities that people use to solve specific tasks.

The Flynn Effect refers to the steady increase in average IQ scores over generations. Researchers attribute this trend to factors like improved education, nutrition, healthcare, and more cognitively stimulating environments.

Intelligence tests are often criticized for cultural bias, but such claims are unsubstantiated. Scientific investigations into the presence of bias on intelligence tests have occurred since the 1970s, and these studies consistently show little or no bias. Today, it is standard professional practice to design tests to prevent any bias from being present and to conduct regular assessments to ensure that no unexpected bias is in the tests.

IQ can fluctuate, particularly during childhood and adolescence, due to factors such as education, environment, and brain development. IQ tends to stabilize in adulthood, though certain cognitive abilities may change with age.

Fluid intelligence is the ability to solve new problems and think abstractly without relying on prior knowledge. It is associated with problem-solving and adaptability and typically declines with age. Crystallized intelligence is the ability to apply learned knowledge and experience, such as vocabulary and factual information. It often remains stable or even improves over time.

Online intelligence tests vary in their quality. Many are designed by non-professionals who lack the training to create accurate tests. A reputable test will be designed by psychologists with expertise in psychological measurement and who publish their analyses in scholarly journals or in a technical manual.

Genetics significantly influences intelligence, but environmental factors, such as education, nutrition, and socioeconomic conditions, also shape cognitive development.

Narrow cognitive abilities, such as solving logic problems, are highly malleable with practice on that particular task. However, the skills built up with this practice only transfer to similar tasks. Training broad abilities (like verbal reasoning or processing speed) can be done, but it takes lengthy practice on many tasks. General intelligence seems to be highly resistant to improvement, though it may be true that engaging in cognitive activities may slow down their decline in old age.
