As an expert in the field of psychology and human intelligence, I can tell you that the concept of "lowest IQ" is not as straightforward as it might seem. The IQ, or Intelligence Quotient, is a measure that is designed to assess human intelligence, but it is not a definitive measure of a person's cognitive abilities. IQ tests are standardized and norm-referenced, meaning they are designed to compare an individual's performance with that of a relevant population.

The lowest score on an IQ test is typically around 40 or below, which is often associated with the classification of intellectual disability (formerly known as mental retardation). However, it's important to note that IQ tests have limitations and do not measure all aspects of intelligence. They are also subject to various influences, including test preparation, cultural bias, and the individual's mental state on the day of the test.

Moreover, the distribution of IQ scores is such that the majority of people fall within the range of 85 to 115, with a standard deviation of 15. This means that a score of 40 is several standard deviations below the mean, which is considered extremely low.

It's also worth mentioning that there are different types of IQ tests, and the scoring can vary. Some tests might have a different scale or method of calculation, which could result in a different score range.

In conclusion, while a score of around 40 or below is often considered the lowest on many IQ tests, it's crucial to understand that this does not capture the full spectrum of a person's intellectual capabilities or potential.

An IQ score of 70 or below is considered a low score. Remember, on most standardized tests of intelligence, the average score is set at 100. Anything over 140 is considered high or genius-level. Sixty-eight percent of all scores fall within plus or minus 15 points of the mean (so between 85 and 115).read more >>
