Thanks for tracking that down. The Hadza still seem to prefer a significantly higher ratio than Americans so, but yes, the effect is much less extreme.
I have a couple methodological problems with both studies, though. The earlier study found a frontal WHR preference around .9 and tested the .4-1.0 range, which may mean that subjects who would have selected a frontal WHR greater than 1.0 had their preference undervalued.
The study on profile WHR only offered choices in the .55-.75 range, which seems problematic if most Hadza prefer WHRs above .8. More importantly, the illustrations used vary profile WHR by adjusting buttock projection and leaving waist-size identical, which makes weight a huge confounding factor.
Drawing strong conclusions from this evidence doesn’t seem possible.
This issue is discussed in some depth in my Ev. Psych. textbook: Evolutionary Psychology: The New Science of the Mind by David Buss. The Hazda women actually have a higher average WHR compared to the global average. Hazda men still prefer a WHR significantly lower than average for Hazda women.
Buss concludes by saying that preference for a low WHR is universal, but modulates somewhat based on the average WHR of local women. He also mentions that high-status men care more about WHR than low status men, which seems to fit obviously with the normal Ev. Psych account.

Which should at least be unsurprising due to anchoring.
