The more we know someone, the higher are our expectations We want them to deeply understand our habits and our wishes. We would like them to react and be a little bit more like us.

The same applies to robots: the more they will look like human beings, the higher will be our expectancies. This is an issue found in "almost human looking" robots or realistic humanoid robots. Our brain focuses on what is not natural and it identifies the robots more like fake human beings rather than good looking robots.

Maybe for now, keeping robots looking as simplistic as possible will be the salvation for the scientists involved in their way to convince future owners.
