Sorry, as used normally, neither the words "reliable" nor "reputable"
imply the other....

"reputable. 1. held in good repute; honorable; respectable; estimable: a
reputable organization. 2. considered to be good or acceptable usage;
standard: reputable speech."
"reliable. 1. that may be relied on; dependable in achievement,
accuracy, honesty, etc.: reliable information."

One of these is a judgement about a quality, the other is a quality. I
can be reliably crazy while actually being reputably sane, or vice-versa.

It is true that people will often use reputation to estimate
reliability, but if you read the words I used, I observed that it was
irrational to dismiss as unreliable a forcefield when it's been observed
to reproduce pertinent observables. If you haven't observed its
performance, however, then it is reasonable to dismiss a forcefield on
the basis of reputation, at the risk of making an error in that
judgement :-) Your original observation used only the word "reliable"...
perhaps you meant "reputable", now that you're talking about force
fields being "well known" and "seen as" :-)
