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).

Einstein's Intelligence QuizEinstein wrote this quiz last century. He said that 98% of the people in the world cannot solve the quiz.
