One example in the book would be the Pirahã who famously don't have words for numbers, they can describe 1 'that', 2 'pair', a few, and many, but not much else. It wouldn't be hard to imagine the harm that would be caused by taking a Whorfian approach would have on such a tribe. In this subchapter he does make the point that it's culture that drives the linguistics, and the subtitle of which is pretty pertinent, 'Tribe without Paper or Pencils Mysteriously Weak at Portraiture'.
Lera Boroditsky is a good mention as well, she authored both of the mentioned studies on Mandarin. The first was 'Does Language Shape Thought?: Mandarin and English Speakers’ Conceptions of Time' (2001) (1). Other researchers have tried to replicate this study (2) and were unable to do so, although they note that all documented examples of linguistic relativity can't be dismissed just from one flawed study, and explicitly note that the effect of the mechanisms is unknown and that the issue is with the claim that language is the mechanism. Boroditsky followed up with 'Do English and Mandarin speakers think about time differently?' (2010) (3). It still seems to be an active area of research and I don't think we'll get a conclusive answer any time soon.
