I think they are claiming that their model more closely matches observed behaviour in certain specific controlled environments. It is a big leap from there to assume that the features of the model map in any useful way to actual features of human reasoning.
I think it’s useful inasmuch as it turns “unknown unknowns” into “known unknowns.” Knowing what you’re ignoring in your approximation seems valuable.
