Interesting you work at Amazon and show how end user experience weights to their pessimal experience.

So.. apply that to Amazon design heuristics like author name search on books, and how Amazon return "in the style of" and "not a book but this guy called Charles Dickens makes jigsaws" as high order matches and consider how the end user experience weights to the pessimal yet Amazon can show on average they make more money doing this..

(Understood that engineers and AWS don't influence UX in the storefront or search)
