Culture can be defined as behavior that is learned and transmitted to members of a group. A child learns a particular behavior through observation as well as through positive and negative feedback from his/her family and peers. A minor point to remember is that this feedback can be overt or covert. Much covert feedback involves nonverbal cues that an outsider to that culture would not understand.

Today in the techno-society there is an almost ironclad consensus about the future of freedom. Maximum individual choice is regarded as the democratic ideal. Yet most writers predict that we shall move further and further from this ideal. They conjured up a dark vision of the future, in which people appear as mindless consumer creatures, surrounded by standardized goods, educated in standardized schools, fed a diet of standardized mass culture, and forced to adopt standardized styles of life. Such predictions have spawned a generation of future haters and technophobes, as one might expect.
