Do Stenning & van Lambalgen actually model the Wason-task 'fallacies' as closed-world reasoning with negation-as-failure?

The claim that the "irrational" Wason selection-task results are better understood as closed-world reasoning with negation-as-failure — humans "reasoning to an interpretation, then from it" — is currently load-bearing for claim-logic-programming-account-rivals-probabilistic-account-of-conditional-reasoning, but the vault holds it only at second hand.

What is confirmed vs. unverified

What to read to answer it

Why it matters

This gates whether claim-logic-programming-account-rivals-probabilistic-account-of-conditional-reasoning can move off seedling. It is also the difference between "a second formal account of the Wason data exists" (safe to assert) and "that account characterizes the data as closed-world reasoning" (currently unread). The capture's own bottom line agreed: it "needs the S&vL primary read before it's publication-solid."
