Is Expert, Expertise?

Do experts really tell it like it is? Most of them are educated beyond the average person while certainly supremely knowledgeable in their fields. What makes me wonder, is how that kind of expertise, matters, when the experts are asked their opinions about things that affect the general public. Are they actually applicable to the average?  If they are queried by media, on their subject area, of course they do have reams of proof given their experience, but does it apply as far as usefulness in public social situations? When an issue comes up, the radio or television interviewers who, let's not forget are chosen for their public popularity in truth, want expert knowledge, run down to the nearest university or call them up for authority on their topics for airing. What they want to know is readily available on their computers, but they also know that everyone listens more closely when so-and-so from the whatever-university speaks it. The professors who are the best for gleanings of this sort, are good speakers because what are professors other than teachers and teachers have to be good speakers to be good teachers. If you've been to university or schooling, you already know that the best teachers are the ones who speak best. You listen and learn. But are they the best source when questions such as what-are-we-going-to-do-about-it come up? I am a fan of polling and drawing out public thought and opinion on certain concerns. I want to hear what the actual thinking is "out there". I don't want to listen to rantings and ravings or saccharine praisings from individuals, but I would love to sift through what my fellow Man opines as digested and presented by people who do that. We always have two sides in the great mixture of societal thinking, apart from the dozing fifty percent Apathetics who do nothing or care to, and think nothing, as they hide behind their bales of hay or "hey, I can't do anything about it, so why should I vote" people. The experts, let's not forget, are usually very financially stable and comfortable folk who are employed in institutions and agencies. They live in the nice neighbourhoods and go about with others of that ilk. They are not your average on-the-street people. The benefit of polling, and there should be a lot more of it, is, that if done correctly, tends to reflect what a societal cross -section thinks it wants, and while the results may seem mundane, it is the norm. The "norm" isn't always politically correct, whatever that means, since "politically correct" could be an artificial pronouncement made by whatever force happens to be in power and it may not be ethical or even correct by general moral behaviours in some societies. Have to be careful about that one these days. Even the experts from universities where most of our current information comes from, could be overly zealous about their pronouncements since their very jobs depend upon what the institutions who hire them, have as their mandates. It gets kind of confusing for we ordinary people who are left with judging, based on our own experiences in life, as to whom to listen to, with any kind of trust.
