im Cooper Journal ist ein lesenswerter Beitrag erschienen: Combating availability bias.
If you’re involved in the design of products, you run into this problem all the time. Stakeholders use their own most easily-retrieved examples to compare against, whether it’s the CEO who is influenced by the pundit he read that morning, or the product manager who knows that one guy who is just like your target market, or the designer who is really designing for himself -- the self being the extreme “available example.” Availability biases leads to poor design decisions because they are based on single, potentially skewed, examples; they also result in thrash because each individual involved in the design has his or her own reference example, making consensus difficult.
