Yeah, well there is a lot of social science research that suggests that when we hear flattery, it "works" as in it enhances our view of the flatterer, even when we don't actually believe their buttering-up words. See here. Even obviously manipulative comments are surprisingly effective:

I think that's kind of disturbing in some ways but maybe Stopdog has a really fine-tuned b.s. detector. Maybe other people who are on the receiving end of flattery don't want to hear it, don't believe it and to paraphrase Groucho Marx, don't want to be in a club that would have them as a member!
