We live in a world today where people are being grouped according to classes. Depending on the wealth you have, your friends and your intelligence and so on.
Intelligence can be measured by taking IQ tests and IQ scores have been shown to be associated with such factors as morbidity and mortality, parental social status, and to a substantial degree, parental IQ. While its inheritance has been investigated for nearly a century, controversy remains as to how much is inheritable, and the mechanisms of inheritance are still a matter of some debate
IQ scores are used in many contexts: as predictors of educational achievement or special needs, by social scientists who study the distribution of IQ scores in populations and the relationships between IQ score and other variables, and as predictors of job performance and income.
The average IQ scores for many populations have been rising at an average rate of three points per decade since the early 20th century with most of the increase in the lower half of the IQ range: a phenomenon called the Flynn effect. It is disputed whether these changes in scores reflect real changes in intellectual abilities, or merely methodological problems with past or present testing.
Several IQ test are available online to help one determine or know his intelligence. One can choose whatever type of test he will get and the results are reliable. It’s very important to be aware of your intelligence for we live is a world that requires intelligence to survive.
