Why is that so, when literacy rate of India is atleast 20 percent higher as compared to pakistan's literacy rate????
You would not give an IQ test that involved reading to some one that could not read.
"The term IQ, or Intelligence Quotient, generally describes a score on a test that rates the subject's cognitive ability as compared to the general population. IQ tests use a standardized scale with 100 as the median score. On most tests, a score between 90 and 110, or the median plus or minus 10, indicates average intelligence. "
"What is this cognitive ability being measured? Simply put, IQ tests are designed to measure your general ability to solve problems and understand concepts. This includes reasoning ability, problem-solving ability, ability to perceive relationships between things and ability to store and retrieve information. IQ tests measure this general intellectual ability in a number of different ways. They may test:
spatial ability: the ability to visualize manipulation of shapes
mathematical ability: the ability to solve problems and use logic
language ability: This could include the ability to complete sentences or recognize words when letters have been rearranged or removed.
memory ability: the ability to recall things presented either visually or aurally"
So your IQ score is relatively stable, no matter what education you acquire. This does not mean that you can't increase your intelligence. IQ tests are only one imperfect method of measuring certain aspects of intellectual ability. A lot of critics point out that IQ tests don't measure creativity, social skills, wisdom, acquired abilities or a host of other things we consider to be aspects of intelligence. The value of IQ tests is that they measure general cognitive ability, which has been proven to be a fairly accurate indicator of intellectual potential. There is a high positive correlation between IQ and success in school and the work place, but there are
many, many cases where IQ and success do not coincide."
