As an expert in the field of cognitive psychology and psychometrics, I can provide an in-depth analysis of the concept of an IQ score and whether it is possible to have an IQ of zero.
Intelligence Quotient (IQ) is a measure of cognitive abilities that are considered to be largely innate. It is designed to reflect a person's relative standing in terms of general mental ability compared to others in a population. The concept of IQ was developed to quantify human intelligence and to predict an individual's academic and professional success.
The standardization of IQ tests is crucial for their validity. When an IQ test is standardized, it means that the test has been administered to a large, representative sample of the population, and the scores are then adjusted so that the average score is 100 with a standard deviation of 15. This allows for a norm-referenced comparison, where an individual's score can be compared to the scores of others in the population.
Now, let's address the possibility of an IQ of zero. In the context of standardized IQ tests, an IQ of zero would imply that the individual has no cognitive abilities whatsoever. This is not a realistic scenario, as even individuals with severe cognitive impairments possess some level of cognitive functioning. The lower end of the IQ scale is typically reserved for individuals with significant intellectual disabilities, but even here, scores are not zero.
It is important to note that IQ tests are not perfect. They are designed to measure certain aspects of cognitive ability, but they do not capture the full spectrum of human intelligence. There are many types of intelligence that are not assessed by traditional IQ tests, such as emotional intelligence, creativity, and practical problem-solving skills.
Furthermore, the concept of an IQ score is based on the assumption of a normal distribution of intelligence in the population. This means that most people score around the average (100), with fewer people scoring very high or very low. However, the distribution is not absolute, and there are always outliers. The tail end of the distribution theoretically extends to negative infinity, which means that there is no true lower limit to the IQ score, although in practice, scores do not go below a certain threshold.
The statement that "the lowest IQ that any human would theoretically naturally have is about -1, using a standard deviation of 15" is an interesting one. This suggests that there is a theoretical limit to how low an IQ score can go, but it is important to understand that this is a statistical construct rather than a reflection of actual cognitive functioning. In reality, an IQ score of -1 or any negative number is not observed because IQ tests are designed to have a floor effect that prevents such scores from being assigned.
In conclusion, while it is theoretically possible to conceive of an IQ score of zero within the framework of statistical distribution, it is not a practical or observed outcome in the context of human cognitive abilities. IQ tests are valuable tools for assessing certain aspects of intelligence, but they are not the sole determinant of a person's intellectual capacity or potential for success.

Lower IQ scores can be (and have been) estimated. This is not really a test, though. It should also be noted that zero is not the lowest theoretical IQ - that is basically negative infinity. The lowest IQ that any human would theoretically naturally have is about -1, using a standard deviation of 15.
