AO3: STRENGTH (holism): Research support by Gould
Previous research by Yerkes suggested that intelligence (as measured by IQ) is innate. THIS IS BIOLOGICALLY REDUCTIONIST. Gould wanted to investigate this
It was found that Yerkes study was invalidated by its cultural bias.
This shows how it is important to consider the role of multiple factors influencing traits before we take an ethnocentric approach - this is because intelligence may be defined differently in different cultures
