Human Perception is so strange

We have impression of strangers base on how they look. Because we don't know the person our first impression becomes quite influential of our opinions of the stranger. Sometimes the face of a person cannot tell much about what kind of person he/she is, yet we will base on a set of memories or experience we had and start to project or imagine what kind of person that stranger is. Of course this is completely subjective and yet almost unavoidable. Which lead me to think whether machine will recognise faces that way. We can imagine that parameters and programs can be set to match certain data or past records in facial recognition software, and by such act certain implications or even conclusion can be made about a person. In a way machine can be completely "objective" in recognising a face without prejudice, yet machine is created by human and certain criteria or preference may be inherent already with softwares are design to recognise faces. In Chinese culture there is the practice of seeing a person face and predicting or projecting the kind of life such a person may have, the idea is the same as palm reading. This kind of practice, even ancient in nature, still based on the use of statistic or pattern recognition. If these criteria are stored in the computer, can the computer do the same job as the face or palm reader?

Back to the idea of imaginaries, just as we imagine what a stranger may be like, we imagine all kinds of things such as social relationship, institutions, places of living, products, foreign lands etc. When we are lack of resources to find out the realities, we fall into imaginations, it is almost a kind of defence mechanism, to fill up the space of unknown.
