Prof Paulsen on "The Cal Tillisch High School Chemistry Lab Method of Constitutional Interpretation"
Over at Balkanization.
The joke is that his high school lab partner, Cal Tillisch, used the following approach to an assignment: "First, draw the desired curve. Then, plot the data. If time permits, do the experiment."
He adds: "I used it as a parable about how not to do constitutional interpretation -- and as a description of how some interpreters (courts, law professors, certainly many first year law students) seem actually to do Constitutional Law, at least from time to time: Pick the desired result, choose an interpretive methodology to match, and then, time permitting, do some research to find supporting evidence."
