Cloud Atlas 'astonishingly different' in US and UK editions, study finds (2016)

Ouch.
And it's standard to "translate" i.e. minorly adapt, but not to abridge or "simplify" as you suggest.
I haven't reviewed the (pages and pages apparently) of differences, but the example they give is this:
>In the UK text, for example, Mitchell writes at one point that: “Historians still unborn will appreciate your cooperation in the future, Sonmi ~451. We archivists thank you in the present. […] Once we’re finished, the orison will be archived at the Ministry of Testaments. […] Your version of the truth is what matters.”
>In the US edition, the lines are: “On behalf of my ministry, thank you for agreeing to this final interview. Please remember, this isn’t an interrogation, or a trial. Your version of the truth is the only one that matters.”
"Mitchell was presented with a substantial list of changes for the US edition".
And the article makes clear that the author was uninterested in tracking the changes: "'It’s a lot of faff – you have to keep track of your changes and send them along to whichever side is currently behind – and as I have a low faff-tolerance threshold, I’m still not very conscientious about it, which is why my US and UK editors now have their assistants liaise closely.... I really never dreamed back then that anyone would ever notice or care enough to email me about it, or that the book would still be in print 13 years later, let alone sell a couple of million copies and be studied or thought about by academics.'"

I presume the editors assumed that most uk kids would have heard of the philosopher’s stone while (so I have been told) the analysis was that American kids would see “philosopher” and say “yuck”.
Out of curiosity which country are you from? Sounds like you haven’t heard of the philosopher’s stone — would be amused at the editors’ judgement if you turn out to be from the UK.
Though I don't know if I would agree that knowledge of such a fictional or mythological object is any more or less sophisticated, so much as a cultural difference in what types of fiction or mythology are more culturally common.
I also don't know anything about what my "sign" is in astrology and I don't think that makes me less sophisticated than those who do. I just have different kinds of useless knowledge.
