Although human thinking is often biased by erroneous intuitions, recent de-bias studies suggest that people's performance can be boosted by short training interventions, where the correct answers to reasoning problems are explained. However, the nature of this training effect remains unclear. Does training help participants correct erroneous intuitions through deliberation? Or does it help them develop correct intuitions? We addressed this issue in three studies, by focusing on the well-known Bat-and-Ball problem. We used a tworesponse paradigm in which participants first gave an initial intuitive response, under time pressure and cognitive load, and then gave a final response after deliberation. Studies 1 and 2 showed that not only did training boost performance, it did so as early as the intuitive stage. After training, most participants solved the problems correctly from the outset and no longer needed to correct an initial incorrect answer through deliberation. Study 3 indicated that this sound intuiting sustained over at least two months. The findings confirm that a short training can boost sound reasoning at an intuitive stage. We discuss key theoretical and applied implications.
