Why Do We Still Use IQ Tests?

Why do we treat a single number like it can define how intelligent someone is? This video explores where IQ testing came from, what it was originally designed to do, how it was later misused, and why intelligence is far more complicated than one score. Alfred Binet developed an early intelligence test in France to identify schoolchildren who needed extra educational support. He never intended it to permanently label people as “smart” or “stupid,” and he warned against treating intelligence as fixed. But when intelligence testing spread to the United States, the idea changed. Tests were used to rank immigrants, classify people as “feeble-minded,” and support the eugenics movement. In the 1927 Supreme Court case Buck v. Bell, forced sterilization under a Virginia law was upheld, becoming part of a darker history in which supposedly scientific measurements were used to justify taking away basic human rights. Today, legitimate IQ tests can still be useful in specific psychological and educational settings. But they are much narrower than the way internet culture often treats them. They measure certain cognitive abilities, including reasoning, memory, and pattern recognition, but they do not capture every form of creativity, judgment, social skill, practical ability, or human potential. Research also complicates the idea that intelligence is simply a fixed number. The Flynn Effect shows that average IQ test performance has changed across generations. Growth mindset research also suggests that beliefs about learning and improvement can influence motivation, persistence, and academic performance. So the point isn’t that every IQ test is scientifically worthless. It’s that using one score as a complete measurement of a person’s intelligence—or their worth—is a misuse of what these tests were designed to do.
