I see it as something like this: Scum(an atheist) has invented a widget which he is excited about selling to other atheists. Scum hires a Marketing Firm to make a survey of atheists to find trends, likes, dislikes etc. common among atheists in order to make his widget more appealing to atheists.
Would the Marketing Firm be able to come up with such a list? I think, somewhere, they probably already have. Although, this isn't strictly a Religion and Philosophy topic.
Also, perhaps the term "bad" has too many negative connotations.
And tbf, I think some of the push-back stems from the fact that no target group wants to believe that their habits, buying trends, likes, and dislikes are in some ways predictable. Everyone wants to feel that they are not unduly influenced by the "machine".
