πŸ“Œ Key takeaways

What did Stephen Hawking say about IQ?

When asked about his IQ, Hawking reportedly replied that he had no idea and that 'people who boast about their IQ are losers.' He preferred to be judged by his scientific work. This attitude makes the commonly cited number especially ironic.

Is the 160 IQ figure verified?

No. The 160 figure is widely repeated but has no documented testing source. It is best treated as an unverified estimate rather than a measured result.

What were Hawking's scientific contributions?

Hawking showed theoretically that black holes emit radiation, now called Hawking radiation, blending quantum mechanics with gravity. He made major contributions to our understanding of black holes, singularities, and the origins of the universe. He also became a global science communicator through his bestseller A Brief History of Time.

How did he work despite his illness?

Hawking was diagnosed with motor neurone disease (ALS) in his twenties and gradually lost most physical movement. He continued his research for decades, eventually communicating through a speech-generating device. His persistence and clarity of thought, not a test score, defined his career.
