First let me say that I thought Steve's description of the way
researchers try to go about modeling stuff was extremely good.
I particularly liked the following paragraph from his earlier
post:

"In research, we constantly uncover data that were not
included in the working model that stimulated the experiment.
Unless such data clearly disprove the model, we generally
reexamine our understanding of the phenomenon in question
and modify the model to account for the new information.
Phil has called this dishonest, but he is wrong." --Steve Clark

This is exactly the way it works, in fact you're usually hoping
to get some surprises in your data since (a) it makes work more
interesting (b) it leads to greater understanding of the phenomena
being studied and (c) it opens the possibility of having some neat
new phenomena named after you :-).

Like Steve, I too get frustrated when trying to explain something
basic like this and get met by this priesthood business. I must
say, though, that the priesthood argument is really convenient.
It allows one to remain ignorant of a subject and still have a
ready-made reply for everything.

So, if what Steve describes above really is dishonest, then I'm a
very dishonest fellow indeed since I engage in this practice all
the time, and am actually engaged in the process right now, as one
of my students has been gracious enough to provide a whole mountain
of data that doesn't fit our models. Jokingly, I told him that
the polymer we're studying needs to take my viscoelasticity course
so it knows how to behave.
