One-Way Mirror

Auf UXMatters bin ich über diesen sehr interessanten Artikel gestolpert: The Myth of the One-Way Mirror.

In the fields of physics, psychology, and biology, there is a phenomenon called the observer effect, which refers to how observation changes the object or person being observed. For example, taking pictures or videos of a tribal culture that has never experienced such technology introduces new concepts into the society and fundamentally changes their behavior, because this is not a natural experience they would normally encounter during their daily lives. This is a major concern for user research and focus groups that are conducted in labs with one-way mirrors. When you place people in an environment where they sense they are being observed, their behavior changes. These changes in behavior can drastically affect your ability to accurately understand how your target market feels about your product or service. In our experience, people tend to focus on positive responses and have a very difficult time being completely open and honest about their thoughts and feelings.

Es lohnt sich da mal drüber zu lesen. Wirklich recht interessant.
