Earlier quoted context omitted.
The trouble is that while most employers say the same thing you say -- that they hire for critical thinking ability and intellectual curiosity / talent -- almost all of them don't actually want that. Instead they want employees who don't think independently; employees who are pliable and will not complain if given drudgery, told to use poor practices, told to make things of poor quality. Everyone says they don't just…
I don't think companies really don't want employees that think independently. These employees come with a ton of upside. However, not everybody turns out to be a star and in some companies (plenty still foster it) they don't want their average employees to be completely rogue.
I think it's more that most companies don't want employees challenging decisions made higher up in the org chart, star or no star. A lot of people don't like having their decisions challenged, especially when they're wrong or they have a hard time defending those decisions.
