UX is like running. new runners often ask me questions like, "how do i breath?" if your design is inspiring your users to question things they've known how to do forever, it's causing them to focus on the wrong things. they know how to breath.
@jbigham I came to a similar conclusion at my last job (after failing to convince a client to not mess with their existing system’s UI): running backwards can be an interesting experience, but you don’t want to be running backwards for your daily jogs. Plus it’s just not that safe to begin with :)
