Completely agree. In my experience every client I've worked with that wanted 'User Testing' or 'A/B Testing' would have lofty goals of having an awesome product backed by science, but at the end of the day were unwilling or unable to actually execute it in a way that did anything other than smush the data into the shape they wanted. They already have results in mind, they just want some data to support their conclusion so they can put it up on a slide for 10 seconds in a meeting.
