"Derek Freeman, whose own research was on the Iban of Borneo"
As we all know, Freeman spent far more time than Mead in Samoa, including living with a Samoan family for 3 years before his Cambridge doctorate, learning Samoan, being formally adopted into the Samoan social hierarchy, returning for many more years, working as a professor at the university of Samoa, and being granted access to the Samoan national archives to research precisely the question under discussion here.
Mead, on the other hand, lived in the US naval station for 8 months, didn't learn Samoan, and surveyed a group of perhaps 100 Samoans.
So can we correct this little deception?
