I agree that celebrity endorsements are effective. The question is why are they effective. I disagreed that celebrity endorsements influence perceived quality. This is different than perceived value which includes many factors, one of which is perceived quality.

A google search provides very little studies that address endorser on perceived quality of the product. The couple I found provided mixed results, with questionable applicability to western audiences (E.g. https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2814907).

Those who are asserting that its obviously true that endorser influences perceived quality apparently do not have the literature behind them.

I think you're (unintentionally) equivocating on value vs quality. The grandparent comment used "quality" in the colloquial sense for value as best I read it. I doubt that anyone running a company thinks that having thier name next to gory images makes people think the skill of the shoe stitching (quality in your meaning?) is worse, but that it reduces the alignment of the pnumbra between the company and the individual reducing the value of company's brand / ability to sell products to the consumer.

That's a plausible reading of the disagreement
