The idea
Construction inverts critique: fix the claim, choose a valid form to carry it, supply premises you can actually defend, and pre-check the twin fallacy of your chosen form.
In practice
A conclusion needing MP needs a defensible conditional and a defensible antecedent — two burdens, chosen deliberately.
Where people slip
Most weak arguments were never designed; they accreted. Form-first construction is the alternative.
