below, a good model developer will constantly test his model against real
data to find where its predictions deviate from actual data. Once the
reasons for the deviation are understood, the model can be improved to
reduce discrepancies from actual data. Thus the model does not serve as a
backup for the data, but its development cycle is intimately connected
with the real data. One question a policymaker can ask to ascertain
whether due diligence is being given to model development, is "Has the
model's performance improved over time?"...."

John Polkinghorne uses the word "corrigible" to encompass the above. It
is a good word to describe one important aspect of science.
