• IQ began as a measure of mental age, but fell out of use due to political correctness and the difficulty of determining mental age for highly intelligent people.
• IQ is still useful in some situations, such as tracking academic performance and determining how many grades children with high IQs can skip.
• Analysis shows that a 4th grade student with an IQ of 145 can score as high as he wants and begin working at the high school level by age 11, and at the college level by age 15.
• The analysis also shows how wasteful the current education system is, as above average people pay a progressive tax in terms of their time to below average people when it comes to spending too much time in the education system.
