When people are looking for a solution to a problem or they have to decide between choice options, they often rely on simplifying heuristics rather than on formal logic or rule-based argumentation. Moreover, the use of heuristics is just as common in real-life settings as in psychology laboratories, and it pervades all aspects of life. For example, when reading a piece of text, people judge the writer to be more intelligent if the text is easier to process (Oppenheimer, 2006), rhyming versions of aphorisms seem to be truer than non-rhyming aphorisms with the same meaning (McGlone & Tofighbakhsh, 2000), and arguments are judged to be stronger if they correspond to the reader’s beliefs (Stanovich & West, 2008). Heuristics do not only influence our judgements, but also affect the ways in which we try to tackle problems. For example, children in a classroom might choose the operations to solve a mathematical word problem based on the title of the chapter that the problem appears in (Van Dooren, De Bock, Evers, & Verschaffel, 2009).
