Problem:
Rewrite this in paragraph format. People once claimed that bigger brains mean higher intelligence. They said adults have bigger brains than the elderly, men bigger than women, and "superior races" bigger than "inferior races," so they assumed these groups were smarter. Broca held this belief even though many facts didn't fit: Some criminals had large brains. Many women were highly intelligent. Some famous, capable people had small brains. On average, Asians had smaller brains than some other groups but often scored higher on intelligence measures. Despite this conflicting evidence and no solid data, Broca kept believing brain size and intelligence were linked. After he died, his own brain was found to be only slightly above average in weight. What do modern studies say? There is a small, reliable correlation: people with larger brains tend to score a bit higher on mental tests. We still don't know exactly why. So, Broca and others were not completely wrong, but they greatly exaggerated the strength and meaning of the relationship. Confirmation bias-seeing what you expect to see-helped keep their beliefs alive even as testing improved. Need Assignment Help?
