> I don’t think all of it is shallow, especially given the format: the book is mostly a prose re-writing of the author’s own peer-reviewed anthropology scientific papers.
That's not the issue. The replication crisis is the phenomenon that many scientific results and conclusions which originate from serious, peer-reviewed research, couldn't be replicated by other researchers, and sometimes not even by the original scientist. This is especially concerning because many results with strong statements – unintuitive ones as well as bias-confirming ones – turned out to be non-existent [1]. It doesn't necessarily have anything to do with "shallowness" or "cocktail-party takes", although the strength of the purported effects, combined with pop-science simplifications and reductions, lend themselves well to such memetically spreading factoids.
[1] The "softer" sciences tend to be much more affected by this than the "harder" sciences.
