A research being funded by some organisation is not bad as such neither does it mean that there is something wrong with the study. But here we're talking about the research findings that we get to see on the internet and how much of it is believable. Most of the research findings that we see here don't give out the name of the market research agency that undertook the research, so how do we know how reliable the source is. Moreover, since you're talking about pointing out gross errors in those studies, tell me how do we do that without vital informations all of which are never given out, e.g., primary and secondary endpoints, study design (sample size, sampling method, location, duration, demographics). Obviously if they don't give out these informations I don't see any reason to treat them as authentic.
Sorry for the late reply. I seem to have missed this.
The research will gain relevance if it is quoted somewhere, where it can be critiqued. Then such lack of information will be brought out. If anybody does not want to undermine one's credibility, then that person should not quote such "research" in the first place.
