However, usability testing is not unlike the age-old question “If a tree falls in the forest and there is no one to hear it, does it make a sound?” In psychology this is called reactivity, sometimes referred to as the Observer Effect. When people are observed, their behavior changes, due to the fact that they are being observed. In usability tests, it is common for participants to attempt to please the person conducting the test. Some participants prefer to give overly harsh criticism, trying to find the faults.

The goal of a usability test is to identify actionable faults in the system from subjective behavior and opinion. The researcher must find what data is, or will be, indicative of how the target user will use the system. Unfortunately, this is more art than science.
