Opening Questions • What do you think is an appropriate measure of intelligence? • How important do you think it is to know how intelligent you are?
IQ Scores & Ratings • What is a good IQ score? What is a high IQ score? What is a low IQ score? These are common questions, particularly after someone finds out their score from an IQ test. • Lewis Terman (1916) developed the original notion of IQ and proposed this scale for classifying IQ scores: • Over 140 - Genius or near genius • 120 - 140 - Very superior intelligence • 110 - 119 - Superior intelligence • 90 - 109 - Normal or average intelligence • 80 - 89 - Dullness • 70 - 79 - Borderline deficiency • Under 70 - Definite feeble-mindedness
IQ Summary • IQ scores reflect general capacity for performing intellectual tasks, such as solving verbal and mathematical problems. • The average IQ score is 100. The standard deviation of IQ scores is 15. • So, this means: • 50% of people have IQ scores between 90 and 110 • 2.5% of people are very superior in intelligence (over 130) • 2.5% of people are mentally deficient / impaired / retarded (under 70) • 0.5% of people are near genius or genius (over 140)
High IQ & Genius IQ • Genius IQ is generally considered to begin around 140 to 145, representing ~.25% of the population (1 in 400). Here's a rough guide: • 115-124 - Above average (e.g., university students) • 125-134 - Gifted (e.g., post-graduate students) • 135-144 - Highly gifted (e.g., intellectuals) • 145-154 - Genius (e.g., professors) • 155-164 - Genius (e.g., Nobel Prize winners) • 165-179 - High genius • 180-200 - Highest genius • >200 - "Unmeasurable genius" • More notes on High IQ and Genius IQ: • Einstein was considered to "only" have an IQ of about 160. • Mensa is a society for people with high IQ, in the top 2% (1 in 50).
