  In the last decade Human-Computer Interaction (HCI) has started to focus
attention on forms of persuasive interaction where computer technologies have
the goal of changing users behavior and attitudes according to a predefined
direction. In this work, we hypothesize a strong connection between logical
fallacies (forms of reasoning which are logically invalid but cognitively
effective) and some common persuasion strategies adopted within web
technologies. With the aim of empirically evaluating our hypothesis, we carried
out a pilot study on a sample of 150 e-commerce websites.
