As an expert in the field of psychology and human intelligence, I can provide you with an informed response to your question about the percentage of the world population with an IQ of 120 or more. It's important to note that intelligence quotient (IQ) is a measure of cognitive abilities that has been standardized to have a mean of 100 and a standard deviation of 15. The distribution of IQ scores in a population follows a bell curve, known as a normal distribution.
According to the **Descriptive Classifications of Intelligence Quotients** you've provided, individuals with an IQ between 120 and 129 are classified as 'Superior,' and those with an IQ of 130 or above are considered 'Very superior.' The table indicates that approximately 6.7% of the population falls into the 'Superior' category, and 2.2% are in the 'Very superior' category. To find the total percentage of people with an IQ of 120 or higher, we simply add these two percentages together:
\[ \text{Percentage of IQ 120 or more} = \text{Superior} + \text{Very superior} \]
\[ \text{Percentage of IQ 120 or more} = 6.7\% + 2.2\% \]
\[ \text{Percentage of IQ 120 or more} = 8.9\% \]
So, according to the provided classification, approximately 8.9% of the world's population has an IQ of 120 or more.
However, it's important to recognize that these percentages are general estimates and can vary based on the source of the data, the specific IQ test used, and the population being studied. Different countries and regions may have different distributions of IQ scores. Additionally, the concept of IQ and its measurement is a subject of ongoing debate and research, with some arguing that it does not fully capture the breadth of human intelligence.
Furthermore, it's worth mentioning that intelligence is a multifaceted construct, and there are different types of intelligence, such as emotional intelligence, social intelligence, and practical intelligence, which are not measured by traditional IQ tests. These other forms of intelligence are equally important for success and well-being in life.
In conclusion, while the figure of 8.9% provides a general estimate, it's essential to consider the complexities and limitations of IQ as a measure of intelligence. Intelligence is a dynamic and multifaceted trait that cannot be fully captured by a single number or test.
