This chapter presents the first experimental study assessing the refutational dimension of the straw man fallacy. This chapter investigates three aspects: the perceived disagreement in straw man fallacies, the role of puisque as a marker of disagreement, and the question wording. The results show that people notice a disagreement when conveyed through a straw man. We will also see that puisque has a mixed role when it comes to the marking of the disagreement. Even though is a strong forewarner, it seems to highlight disagreement only in certain circumstances (when the experimental questions are linked to the argument and formulated negatively). As for the question wording, we see that it does not affect the perception of disagreement in the type of experimental setting used in this book.
