IQ: Refuting Popular Myths


Introduction l.jpg
Introduction

  • Intelligence (IQ): one’s overall cognitive ability, including knowledge, memory, mental quickness, and problem solving

  • Standardized IQ Tests:

    • Vocabulary, arithmetic, pattern completion, puzzles, information, memorizing numbers

  • Most cognitive tasks provide a rough measure of intelligence: ACT, SAT, GRE, exams, papers, social problem solving


Intelligence doesn t exist l.jpg
“Intelligence” Doesn’t Exist?

“There’s no such thing as intelligence. It’s just used to label people as smart or dumb, and these labels are meaningless. The ACTs are worthless, and colleges should stop using them.”

Sorry, Mr. Hippie

  • “Intelligence” is a valid construct (concept)

  • Validity: any construct, such as intelligence, is valid if it predicts relevant outcomes

  • Intelligence tests predict…

    • Occupational status − Pronunciation

    • Success at work − Mental math

    • College grades − Criminality

    • Emotional Adaptation − Learning speed

  • In a few hours, most psychology students could design a simple intelligence test that would predict college grades (r = .50)

  • Intelligence tests correlate r = .30 to .90 with scores on any cognitive task (r = .75 on average)

  • Larger correlations than any other area of psychology


Multiple intelligences l.jpg
Multiple Intelligences? simple intelligence test that would predict college grades (

“Everyone has different abilities. Someone can be bad at one type of task and good at something else. There are many types of intelligence, and most people are good at something.”


Sorry dr sternberg l.jpg
Sorry, Dr. Sternberg simple intelligence test that would predict college grades (

  • Sternberg (3), Gardner (8), Guilford (150)

    • Not supported by research

  • General mental ability (g): All of the different types of intelligence are so highly correlated, they are considered to measure the same thing

  • Smart people do well on most tasks

  • In rare instances, it may be useful to examine fluid vs. crystallized intelligence


Iq is entirely heritable l.jpg
IQ is Entirely Heritable? simple intelligence test that would predict college grades (

“Intelligence is solely the product of good genes, and those that fail to succeed in society are genetically inferior”


Sorry mr murray l.jpg
Sorry, Mr. Murray simple intelligence test that would predict college grades (

  • Like most traits, intelligence is strongly influenced by both genes and environment

  • Children: family environment matters most

  • Adults: genes play a bigger role, as people choose environments that maximize their genetic potential

  • Teratogens, malnutrition, poorly funded schools, and racism may have huge effects


Racist iq tests l.jpg
Racist IQ Tests? simple intelligence test that would predict college grades (

“Psychologists are racists. IQ tests are just used to discriminate against minorities, who score lower on these tests. Psychologists should be ashamed.”


Sorry ms grace l.jpg
Sorry, Ms. Grace simple intelligence test that would predict college grades (

  • African Americans score 10 point less

  • Unscrupulous/ignorant psychologists have occasionally used this to say that minorities are inherently inferior

  • BUT we know IQ is not entirely genetic

  • Lower IQ scores are likely a result of discrimination in education (bad schools)

  • IQ tests just show that we need to level the educational playing field


It s unchangeable l.jpg
It’s Unchangeable? simple intelligence test that would predict college grades (

“Intelligence is genetic and therefore unchangeable. The smart will always be on top, and the slow will always be in their way.”


Sorry mr herrnstein l.jpg
Sorry, Mr. Herrnstein simple intelligence test that would predict college grades (

  • Intelligence is a relatively stable trait, but change is possible

  • “Verbal” or “crystallized” intelligence is based on knowledge of information

  • Flynn effect: IQ increases each generation

  • IQ shifts when people enter adulthood

  • IQ changes reliably with age

Iq is not important l.jpg
IQ is Not Important? simple intelligence test that would predict college grades (

“Who cares about IQ? Success depends more on personality, motivation, hard work, paying attention, and who you know”


Sorry ms coulter l.jpg
Sorry, Ms. Coulter simple intelligence test that would predict college grades (

  • IQ is the best predictor

  • Motivation and personality are important too

  • But it’s hard to measure motivation, and personality measures are easy to fake

  • Generally, IQ tests are incredibly useful

    • Choosing employees or students

    • Helping people who are having academic problems: too smart, too slow, learning disorder
