Richard Cooper - What would convince me that my theory was wrong? is a PowerPoint presentation in 15 slides.
it begins summarizing Lakatos's "A Critique of Naïve Falsification":
* All theories include peripheral assumptions (hard core)
* Anomalies can always be accommodated via adjustments to peripheral assumptions (protective belt)
Adjustments to peripheral assumptions reminds me of
"monster-barring" which, in turn, seems to have a connotation of weaseling out (apparently
lawyers do something like monster-barring)
He later uses ACT-R and Soar as examples.
Harvey A. Cohen (1974) - THE ART OF SNARING DRAGONS seems like an interesting paper that discusses monster-barring in physics.
