The term self-concept is a general term used to refer to how someone thinks about or perceives themselves. It is an important term for both Social Psychology and Humanism.
IQ stands for Intelligence Quotient. It is a score that combines the mental age of a person with his chronological age. For testing purposes, the mental age is determined by a series of standardized test questions, known as the IQ test. It is estimated that well-known scientist Albert Einstein had an IQ of 160 or more.
A normal intelligence quotient (IQ) ranges from 85 to 115 (According to the Stanford-Binet scale). Only approximately 1% of the people in the world have an IQ of 135 or over. Genius or near-genius IQ is considered to start around 140 to 145. Less than 1/4 of 1 percent falls into this category. Around a century ago, it was a common practice to tag high IQ people with the genius label.
