Our brain is the intellectual center that allows thought, learning, and creativity.

But due to various activities that we do every day, we lose extra cellular fluids and millions of neurons, specialized cells transmitting nerve impulses. This may cause our brain to not function as sharply. It is also one of the factors affecting personality and intelligence.

To avoid being intellectually and emotionally inactive, it is important to stay mentally sharp by working your mental muscles everyday.

You should do activities that involve mental stimulation. These can include playing logic games, as well as taking practice IQ tests or EQ tests.

It is also very important to stay physically healthy. Proper diet is one of the keys. Eating food rich in Vitamin B, protein, and folic acid are just a few examples. It’s important to avoid harmful substances like cigarettes or harmful drugs to maintain the health of your brain, and to be intellectually and emotionally intelligent.

You should also have social interactions. A good conversation with a friend or acquaintance contributes to improving your intellectual well-being and emotional capability. Having a network of connections to other people is beneficial for brain health and well-being.

A healthy brain means being intellectually and emotionally intelligent. If you are, you will be happier. You should always be improving, moving forward and not backwards.

They say, if you dont use it you’ll lose it. And that will surely happen if you don’t do what is necessary for the gifts we’re given. Don’t let the day pass you by without doing something worthwhile. There’s a lot to do to be productive. And self examination will tell you there’s a lot to do to improve your personality and your intelligence.

Test that attempts to find out the innate intellectual ability, and not learned ability.

It is now generally accepted that a kid’s results in an iq test can be affected by it’s environment, cultural and ethnic background, as well as teaching. 

There is widespread  questions about the reliability of IQ tests, but they are still often used as a diagnostic tool when children display learning  problems.

The French psychologist Alfred Binet (1857–1911) devised the first intelligence test in 1905.

The IQ (from  the German Intelligenz-Quotient), was coined by the German psychologist William Stern in 1912 as a proposed method of scoring early modern children’s  intelligence tests.

It is calculated according to the formula: IQ = MA/CA x 100 in which MA is ‘mental age’ (the age at which an average  child is able to perform given tasks) and CA is ‘chronological age’, hence an average person has an IQ of 100 ± 10.

Although the term “IQ” is still in common use,  the scoring of modern IQ tests such as the Wechsler Adult Intelligence Scale is now based on a projection of the subject’s measured rank on the Gaussian bell  curve with a center value (average IQ) of 100, and a standard deviation of 15, although different tests may have different standard deviations.

Intelligence tests were first used on a  large scale in the USA in 1917 during World War I for two million drafted men, and their subsequent widespread use for education and employment decisions has  provoked protests from minority groups who contend the tests are culturally biased and discriminatory.

IQ scores have been shown to be associated with such factors as morbidity and mortality rate, parental social status, and to a significant degree, parental  IQ. While its heritage has been inquired for almost a century, controversy remains as to how much is inheritable, and the mechanisms of inheritance  are still a matter of some argument.

IQ scores are used in many contexts: as predictors of educational accomplishment 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 mean 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 problems with past or present testing methods.
