Document Summary
We use intelligence tests to give a numerical value to ones mental abilities by comparing them to others. Francis galton (1822-1911) had great enthusiasm in measuring human traits that lead to the movement. His goal was to by means of tests on strength, reaction time, sensory precision and even head size. Despite his efforts, no correlation whatsoever was found between general mental abilities and the traits. Alfred binet if you perform the way a typical 10 year old would, then your mental age is 10 years old, regardless of your real age. Ie, people saw your level of intelligence and not really who you are. Lewis truman- developed the current stanford-binet intelligence test. The test measures iq intelligence quotient- mental age divided by chronological age(real age) times 100. If you are 12 years old(chronological age) and your mental abilities are the same as those who are 12 years old (mental age).
