Typecasting and Profiling
One must have heard so many stories about someone getting profiled and there would be others who might have gone through the experience at international airports. Stories have been told so many times that we ourselves have kind of created a profile of immigration and security officials of foreign lands.
I would like to extend here, to one of the blog posted by Shekar Kapur. His blog recollects an incident at a US airport.
You would notice how he himself typecasts the officials and very conscious about everyone around, to such an extent that he initially believes all airport officials are monitoring his moments.
Thus, I believe Typecasting and Profiling are among the few of basic traits in human and come as standard configuration. Some are knowledgeable enough to suppress (or override) and others ignorant (or arrogant) to express.
