🧠 The Science Behind IQ: Is Intelligence Fixed or Fluid?


Video: The Problem With IQ Tests.








IQ is often misunderstood as a static, inherited trait. But science paints a more nuanced picture.

What IQ Tests Measure

IQ tests like the Wechsler Adult Intelligence Scale (WAIS) assess:

  • Verbal comprehension: vocabulary, understanding language
  • Perceptual reasoning: solving puzzles, spatial reasoning
  • Working memory: holding and manipulating information
  • Processing speed: how quickly you process simple info

These tests are designed to gauge general cognitive ability, but they don’t capture creativity, emotional intelligence, or wisdom.

Genetic Influence: The Fixed Part?

Twin studies estimate that genetics explain between 34% and 65% of IQ variability, depending on the test and age group (Educational Neuroscience). Genetics sets a range, but not a fixed point.

Environmental Influence: The Fluid Part

Environmental factors like:

  • Quality of education
  • Nutrition and health
  • Socioeconomic status
  • Parental involvement
  • Stress levels and mindset

can dramatically influence IQ scores and cognitive development. The Flynn Effect shows IQ scores rising globally over decades due to these factors, not genetics.

Neuroplasticity: The Brain’s Secret Weapon

Our brains are plastic — they can change and rewire throughout life. This means cognitive abilities can improve with training, learning, and lifestyle changes.

📜 A Brief History of IQ Testing and Its Evolution

a close up of a book with a poem on it

IQ testing began in the early 20th century with Alfred Binet, who designed tests to identify children needing educational support.

Early Milestones

  • 1905: Binet-Simon scale introduced in France.
  • 1916: Lewis Terman adapted it into the Stanford-Binet test, popularizing IQ as a quotient.
  • 1939: Wechsler Adult Intelligence Scale (WAIS) developed, measuring multiple cognitive domains.

Evolution Over Time

  • Early IQ tests focused on academic skills and verbal reasoning.
  • Modern tests include non-verbal components and measure working memory and processing speed.
  • Criticism has grown over cultural bias and narrow definitions of intelligence.
  • The concept of multiple intelligences (Howard Gardner) expanded the view beyond IQ scores.

IQ tests remain widely used but are now seen as one piece of the intelligence puzzle, not the whole story.

🔍 What Exactly Does Your IQ Score Measure?

  • Nutrition, sleep, and stress management are critical.
  • Parental mindset matters: a growth mindset buffers stress effects on infant brain development (Harvard Gazette).
  • Socioeconomic status affects access to resources that nurture intelligence.

Interaction: Genes x Environment

  • Genes set potential; environment determines how much of that potential is realized.
  • In affluent environments, genetic influence on IQ is stronger; in deprived settings, environment dominates.
  • Teacher quality can amplify or limit genetic potential.
