How do I know you guys arent just lying to everyone?

Some questions are hard to answer but easy to check an answer once you
have one.  That's the kind you'll probably want to ask here.

Scope for checking may come when someone states their search strategy
or gives links to articles on different sites supporting an answer.

For example here's a google answer that was disputed
    http://answers.google.com/answers/threadview?id=537216
and where you may be able to assess the truth of the opposing views.

You don't.  And we're not always right.  But most of the time we are.

I know that there is some kind of Code of Conduct for GA-Researchers
(Can't snig a commenter's earlier posting and post the information an
answer, unless meaningful additional information is provided, for
example).  It is obvious that they are also required to explain their
search strategy, thereby allowing anyone to check for him/herself. 
And even where it is apparent that they know the answer from their
profession, they will as a rule support it with hyperlinks.  If not,
they will say so.
And, if the questioner is unhappy with the answer, or if anyone
clearly refutes it, they will have the posting removed.

I was the original poster of this question and actually I am very
pleased with the answer.

Glad you are satisfied with Bozo's and my comments.  We are only
talking about GA-Researchers, of course.  Mere registered users, like
the three of us, could be BSing, but on a serious question, someone
would give our evil fingers a virtual rap.
I rather doubt that a Researcher will post an answer now, out of
professional modesty, as Efn-ga's having posted just a comment
suggests, so you might close the question.  Apparently, GA keeps
statistics on unanswered questions, and it looks better for the
Researchers if there are fewer of them.  (I better go back and do the
same for a couple of mine!)

Short answer: you dont.

Long answer: the knowledge of many outweighs the few. This allows the
collective knowledge to come through, and provide you with the best
answer avaliable. Many people of many backgrounds and specialties use
this service, and thusly there is a large pool of knowledge to draw
from. It also means that the right answer is here somewhere, and will
usually find its way to you.
