Yes, it's the detailed deconstruction of the Freeman-Mead controversy, which I always feel Freeman basically cheated on in the first place by only starting it once Margaret Mead was safely dead. This book does nothing to change my feelings that Freeman's case was always a bit dodgy (different informants, different periods, different genders, and doubtless different questions asked - of course they were not going to have identical findings, but honestly, is it really the habit of experienced anthropologists to take as gospel what their male informants tell them a) about the virtuousness of their unmarried sisters and b) about their own sexual exploits? and assume that these automatically trump what girls themselves told someone else decades previously?).
Shankman reveals just how dodgy (and bizarrely obsessive, since he published two books about it) Freeman's case was. I didn't realise that his entire case was about tearing down only Coming of Age in Samoa, which Mead deliberately wrote as a popular account of her Samoa fieldwork (very much her anthropological apprenticeship), on which she also published a ethnographic field report which one gathers is as dry and professional as anyone might wish, and which he ignored. Also totally leaving out all her other, subsequent, work on different cultures, in museum anthropology, in syntheses, etc.
This book is not uncritically hagiographical about Mead and Coming of Age in Samoa, but on the whole, she comes out of this a great deal better than Freeman, including being open to listening to views she didn't agree with and even advocating for their hearing.
Vast swathes of Mead's career were not all Freeman left out in his critique. Shankman's micro-readings and comparisons indicate: selective quotation, misinterpretation of what he does quote, leaving out anything that might contradict his picture, and not giving anyone access to his sources, such as an interview with a very elderly Samoan woman who had been one of Mead's informants. I.e. it all looked very scholarly, and he made a big thing of how many sources he had consulted and FACTS he had ascertained, but it had shot off at some fairly extreme angle from the actual processes of academic argument and debate. For someone who made a big deal of how SCIENTIFIC he was, Freeman does seem to have rather ignored Popper's notions about falsifiability, in spite of frequently name-checking him.
It is clear that, at the very least, Freeman was a troubled man with a lot of problems. During his fieldwork in Sarawak there was some kind of weird episode involving Tom Harrisson, and in later years he was given to writing long letters to people who disagreed with him, including threats to destroy their careers in the discipline.
What he did vis-a-vis Mead, as Shankman states, was to create a good story which could be presented in a way that was attractive to the media (controversy!) even though right from the get-go fellow-anthropologists were more hesitant to accept Freeman's conclusions, or downright critical. His line intersected with concerns of the period in which he published his attack on Mead, and although it doesn't seem that there was actually a lot of difference between Mead's and Freeman's positions on the interactions of nature and culture, he presented her as a simplistic cultural determinist and made his position very attractive to biological determinism, which was having a serious resurgence at the time.
Shankman, whose area is also Samoa, is additionally interesting on changes in Samoan society between the time when Mead was working and when Freeman was, and in particular, examines the response of Samoans themselves to both anthropologists.
This is a very rich book - including Shankman's personal encounters with both Mead and Freeman, though as a junior colleage, indeed, his first meeting with Mead was as an undergraduate, in both cases. It's illuminating about that difference between how work is regarded by people in the field and non-experts (about which I have some striking examples myself that I could give, and have on occasion) and how certain works (both Mead's and Freeman's) became popular in specific historical contexts, and in particular the role of the media and being media-savvy.
Though on that point, there is an amusing bit of meta of which Shankman is obviously not aware in his citation of some contentions on sexuality in the Jazz Age from The Technology of Orgasm... which also has its moments of wild segues from possibility > likelihood > certainty in constructing its case.
I also wonder whether Shankman is possibly overlooking the attractions of attacks on a Powerful (and indeed sexy) Mother Figure and the feeding of misogynistic attitudes into the furore and the proliferation of the meme of Mead Wuz RONG.
