I don't work at Amazon, but worked at a similar (European, national) retailer: You really have to walk the line between ratings-per-SKU and aggregate ratings sometimes. In an ideal world, the reading experience of a Kindle book is the same as the physical book. So someone might argue that ratings should be aggregated across all version of the product. Would you expect different ratings for hardcover/paperback versions of books? Probably not, at least assuming people review the content of the book, not its appearance. Similarly, do you really want people to leave ratings on a black shirt in size L, and that rating not apply to all sizes and colors? I assume someone at Amazon thinks about this, and the defaults (fashion => merge, books => merge, electronics => donotmerge) etc. do OK until complaints come in. There's no profit in not being heavy-handed.

Right, the issue though is that there is a much larger gulf between the eBook and print book than there is between the paperback and hardcover. And the delivery mechanism can greatly affect your enjoyment of the book. It's about more than just appearance. Source code in particular, does not often work well on a Kindle's tiny screen.

  Although maybe it does if you read it on a full-size tablet. In general, I mostly avoid buying books I know aren't 95% text in Kindle format unless they're very cheap or are from a known publisher for things like guidebooks. They can work well but it's definitely hit or miss. (I also just don't like ebooks for certain types of references where I want to stick post-its etc.)

  I personally fully agree! But I imagine a PM at Amazon was presented with the question "Should ratings of all versions of books be merged?". Unless they really really cared (or personally had experienced dramatic differences between versions of books before), they probably said "Yeah sure". (I'm also biased a bit in that I assume that implementing this more fine-grained would cost more than $0).

I would expect different ratings, because when you buy a book it is not just the content you are buying. The reason people look at reviews is to decide whether or not to buy, and the physical quality of the book is important for that. If the hardback is fine but the paperback has pages out of order and that fall out when you turn them, then people who bought the paperback are going to (quite justifiably) be leaving reviews with the lowest rating possible. This doesn't help me at all when I'm considering buying the hardback.

  Well, people can explain their low ratings. "A real page turner but the paperback printing and binding were awful." The problem is that, if you rate at the SKU level, you now have different reviews for every size and color of shirt. "The green color isn't at all like what was on the product page." The reality is that for most books (pretty much all fiction, most trade paperbacks without a lot of illustrations/code/etc.), Kindle format is just fine even on a e-paper reader.

    > "The green color isn't at all like what was on the product page." That's a valuable review though; if a green shirt is not as advertised I want to know that before I buy it.

      Yes, but it's pretty much as valuable lumped in with the other shirt reviews whereas if you split out reviews for each individual SKU, many of the items will end up not having reviews at all.

        If a particular variation has no review, I want to know that before I buy it. What good is a bunch of 5 star reviews for a red shirt if the lime green shirt I want to buy is actually the color of baby shit?

I expect a review of a book to be a review of the book. The contents of the book are only one aspect of the book. The digital or physical form of the book is no less important to me when I am looking to buy the book, particularly when the digital or physical form of the book might very well be irredeemable trash (rendering the quality of the contents irrelevant.)

It seems like there's room for compromise. You could simply assign a lower weight to reviews for a different size/format. Or you could split ratings entirely if (and only if) the review averages are significantly different.
