6 Interesting Facts about IQ Tests

IQ tests have been in use right since the 19th century for measuring intelligence of individuals. This standardized test has been used across the years by educators and psychologists to foretell a person’s academic performance and career success, and also to diagnose mental retardation and disabilities in learning. Although there were some questions about its reliability and accuracy over some decade, IQ test remains the most commonly used test for judging mental ability. Here are some interesting facts about IQ tests.

1. Variation in Women’s and Men’s IQ Scores

Studies have shown that there is a slight variation in the IQ test scores of women and men. Both are virtually equal in terms of IQ, men tend to score higher in certain subjects such as spatial awareness, while women tend to score higher in emotional intelligence and language development.

2. Relation to Breastfeeding

Breastfeeding has been proven to raise children’s IQ and improve their academic performance. In a 2008 study conducted for 6.5 years, it was seen that children who had been breastfed had higher scores and showed overall better academic achievement.

3. For Diagnosing Mental Retardation

Though today IQ tests are used to find intelligence level and predict academic success, they were once used primarily to diagnose mental retardation. According to Binet-Simon’s test, an IQ score below 70 was supposed to be a sign of mental retardation.

4. For Measuring Certain Intellectual Skills

The traditional IQ test measures only certain intellectual skills, like mathematical, analytical and spatial skills. It doesn’t measure artistic, creative, emotional, leadership and social skills or other abilities that can also define a person’s intelligence.

5. Environmental Factors Affecting IQ

Many environmental factors like socio-economic status, malnutrition, support structure, stress and attitude have an effect on IQ. It has also been observed by scientists that quality of education can also hugely impact IQ scores. Moreover, students of poorly funded schools usually score less than students of financially stable schools.

6. Birth Order has No Effect

The theory that the eldest children are more intelligent and have higher chances of succeeding in life than their younger siblings is just wrong. The intelligence of a child is not dependent on the order in which s/he is born, but is more dependent on her/his personality, age difference, gender, parental age and family size.
