Flynn credits women scoring higher as a result of increased opportunities and education for women within the last century. He also believes that education’s transition from rote memorization to focusing on logic and analytic skills has played a part in the gender IQ shift.
“As we enter the modern worlds, our minds change just as our automobiles have changed,” Flynn explained. “Where women can have an equal chance to interface with the modern world, they equal on IQ and surpass on academic performance.”
He suggested that these advantages also open doors for women to succeed in professional fields, even though there are other social factors influencing women’s success in those spheres.
Previous human studies have found differences in males and females on factors such as brain size, verbal and spatial abilities, as well as brain disorders.
