Indeed, we have seen that, under the force of these general cognitive mechanisms, deciding on appropriate objects, classes, and relations is sometimes influenced by irrelevant surface clues or everyday meanings of these concepts, thus leading to inappropriate choices. Intuition is a powerful tool, which helps us navigate successfully through most everyday tasks, but may at times get in the way of more formal processes. We hope this article may contribute to better understanding of this problem, and point the way to thinking about its resolution. ^c
