Want to know ? Classification of Human IQ Levels
What is IQ? Intelegent quotient or IQ is a number which explains the level of intelligence of a person compared with his fellow in a population.
How do I know the level of IQ (Intellegent Quotient) someone? Generally done through a psychotest that has many methods or ways. However, experts differ in determining the size of the question of human IQ levels. Here is the classification of human IQ levels in the opinion of some experts:
The IQ classification is different for each test method used.
#Stanford-Binet classifies normal IQ values ranging from 85 to 115.
#Lewis Terman classifies normal IQ scores in the 90 to 109 range.
#Wechsler classifies normal IQs at 100 with tolerance values of 15 (meaning 85 - 115). Due to this difference, then in addition to the value of IQ obtained, must also note what test method is used. For general classification, when we do not know what method is used. Can use the classification below (result of compromise of three method above).
70 - 79 = Low IQ level or mental retardation 80 - 90 = Low IQ level still in normal category (Dull Normal) 91 - 110 = Normal IQ level or average 111 - 120 = High IQ level in normal category (Bright Normal ) 120 - 130 = Superior IQ rate 131 or higher The IQ level is very superior or genius.
With an average normal human IQ is in the range of 91-110, the following are people who have above average intelligence, perhaps some of them you've known before:
- Leonardo da Vinci Universal Genius, origin Italy, IQ 220
- Johann Wolfgang von Goethe - Germany: 210
- Kim Ung-Yong, physicist, South Korea: 210 Gottfried Wilhelm von Leibniz - Germany: 205
- Blaise Pascal Mathematician & religious philosopher France: 195
- Garry Kasparov, chess Russia: 190
- Sir Isaac Newton Scientist England: 190
- Galileo Galilei Physicist & astronomer & philosopher Italy: 185
- Johannes Kepler Mathematician, physicist & astronomer Germany : 175
- Johann Strauss Composer Germany: 170 Martin Luther Theorist Germany: 170 Plato Philosopher Greece: 170
- Ludwig van Beethoven Composer Germany: 165
- Johann Sebastian Bach Composer Germany: 165
- James Watt Physicist & technician Scotland: 165
- Wolfgang Amadeus Mozart Composer Austria: 165
- Bill Gates CEO, Microsoft USA: 160
- Albert Einstein Physicist USA: 160
- Paul Allen Microsoft cofounder: USA 160
- Nicolaus Copernicus Astronomer Poland : 160
- Benjamin Franklin Writer, scientist & politician USA: 160
- Stephen W. Hawking Physicist England: 160
- Wolfgang Amadeus Mozart: 154
- John Quincy Adams President USA: 153
- Bonaparte Napoleon Emperor France: 145
- Adolf Hitler Nazi leader Germany: 141
But the list above is just a small amount and does not cover everything.
Explanation of IQ levels in general:
A. Idiot IQ (0-29) Idiots are the least retarded group of individuals. Can not talk or just say a few words. Usually can not take care of himself like bathing, dressing, eating and so on, he should be taken care of by others. An idiot child lives in bed for the rest of his life. The average development of intelligence is the same as a normal 2-year-old child. Often the age is not long, because in addition to low intelligence, also the body less resistant to disease.
B. Imbecile IQ (30-40) The imbecile Children Group is a higher level than the idiot child. He can learn the language, can take care of himself with careful supervision. In imbecile can be given light exercises, but in life is always dependent on others, can not be independent. His intelligence is the same as a normal child of 3 to 7 years old. The imbecile children can not be trained in regular school.
C.Moron or Debil IQ / Mentally Retarted (50-69) This group to some degree still can learn to read, write, and make simple calculations, can be given certain routine jobs that do not require planning and solving. Many of the children of this debil get education in extraordinary schools.
D. IQ dull / bordeline stupid group (70-79) This group is above the backward group and below the normal group (as the limit). By difficulty with some obstacles, the individual may undertake a secondary school but it is very difficult to complete the last classes in SLTP
E. Normal low (below avarage), IQ 80-89 This group belongs to the normal, average or moderate group but at the lowest level, they are a little slow in learning, they can finish junior high school but a bit difficult to be able to complete the tasks at senior high school level.
F. Normal, IQ 90-109 This group is a normal or average group, they are the largest group of the percentage in the population.
G. Normal high (above average) IQ 110-119 This group is a normal group of individuals but at a high level.
H. Smart (superior), IQ 120-129 This group is very successful in school / academic work. They are often found in regular classes. Class leaders usually come from this group.
I. Very intelligent (very superior / gifted) IQ 130-139 Very superior children are more capable in reading, have excellent knowledge of numbers, vast vocabulary, and quickly understand abstract notions. In general, health factors, agility, and strength are more prominent than normal children.
J. Genius IQ 140> This group of abilities is extraordinary. They generally have the ability to solve problems and find something new even if they are not in school. This group is located in all races and nations, in all economic levels of both men and women. Examples of these geniuses are Edison and Einstein.
The above description describes the level of intelligence in size cognitively, the old view shows that the quality of intelligence or high intelligence is seen as a factor that affects the success of individuals in learning and achieve success.
But recently has developed another view that states that the most dominant factor affecting the success of individuals in their lives is not solely determined by the high intellectual intelligence, but by the emotional stability factor that is the expert Daniel Goleman called Emotional Intelligence (emotional intelligence).
Based on his observations, many people who fail in their lives not because of their low intellectual intelligence, but they lack the emotional intelligence even intelligence.
IQ - Description -% of the world population 130+ - Very superior - 2.2% 120-129 - Superior - 6.7% 110-119 - Plus average - 16.1% 90-109 - Average - 50% 80-89 - Rata - minus - 16.1% 70-79 - Boundary - 6.7% Below 70 - Very low - 2.2%.
