The Surprising Science of Intelligence: Why IQ Matters More Than We Think

When Stephen Hawking was asked about his IQ, he famously replied, "I have no idea. People who boast about their IQ are losers." This sentiment captures a curious paradox in our society-many intellectuals publicly dismiss intelligence testing while privately acknowledging its validity. Despite being one of psychology's most robust fields, intelligence research remains deeply controversial. Yet the evidence is clear: intelligence testing isn't just meaningful-it predicts education outcomes, career success, health, and even how long you'll live. In our increasingly complex, knowledge-based world, understanding intelligence has become not just academically interesting but practically essential for addressing challenges from educational inequality to cognitive aging.
