David;
Aha ! .… Science isn't about the truth !!
And we do know a lot about the framework, or the contexts.

Its an interesting topic. I think its all about balance.
It seems, the shorter the answer, the less balance delivered.
Perhaps an engineering tradeoff approach is required !

Its been an interesting discussion for me (I wish I could get out of it !

)
Mark's approach, and his answers certainly show good balance.
And I totally support your honesty (truth) approach, at all times.
Cheers
