Maybe I’m missing something obvious, but… what makes a focus-group groundhog day attack more useful than just, you know, having multiple focus groups?
It eliminates variation between focus groups. If people are as deterministic as depicted in MoR chapter 27, the slightest variation in behavior would be a clue about how to refine the ad.
That sounds like it would lead to overfitting.
