Most papers describe how a problem is solved using the authors' methods or design expertise.
However, this paper is about how the authors deliberately caused a problem in an interface. This is not as strange as it seems. Being able to cause a normally infrequent problem when required is a good sign that our techniques offer strong analytic leverage. Furthermore, reliably producing a problem is a prerequisite for experiments on methods to relieve that problem. Consider a typical screen button.
