No, there is no correlation between the speed at which someone speaks and their IQ.
According to research, speech rate is not an indicator of intelligence. Language use varies among individuals for numerous reasons, and these variations should not be considered deficiencies. In other words, speaking quickly doesn't mean someone is smarter, just as speaking slowly doesn't mean someone is less intelligent. As the reference states, "There is no inherent connection between the rate of speech and levels of intelligence, truthfulness or kindness. Language use differs for all sorts of reasons, and differences are not deficiencies."
| Feature | Fast Talker | Slow Talker |
|---|---|---|
| Intelligence | Not inherently linked to higher IQ | Not inherently linked to lower IQ |
| Communication | Can be perceived as energetic or nervous | Can be perceived as thoughtful or hesitant |
| Contributing Factors | Personality, context, emotional state | Personality, context, emotional state |
Instead of focusing on speech rate as a marker of intelligence, it's more accurate to assess intelligence through validated IQ tests and other comprehensive assessments.
