 We are all amateur psychologists, because most of what we do is designed to influence what others think of us. What do people look for when sizing up others during an initial meeting? How do these judgments influence their conduct? And how far will they go to hit it off? This program analyzes the subtle dynamics of meeting new people as Day One in the Human Zoo unfolds. In addition, other researchers explore the impact of first impressions at a job interview, how physical attractiveness affects success, the parameters of personal space, and facial expressions associated with deceit. Dr. Mark McDermott and Dr. Phil Zimbardo used hidden cameras to observe how a group of strangers will interact during the first day of what the subjects know is a psychological experiment. Immediate friendships and hostilities are watched by the professors; these scenes are inter-cut with other researchers exploring such dynamics as the impact of first impressions at a job interview and how physical attractiveness affects success. Actor/comedian Charlie Skelton, among others, intrudes on the personal space of British citizens who do not know they are being filmed, and three test subjects are required to undergo the temptation of robbery and then filmed while they deny their guilt to an inquisitor. The documentary returns in the end to The Human Zoo to dramatize how the group of strangers has bonded or formed private friendships in emotional and occasionally bizarre ways, as when one subject, Richard, who had felt himself to be an outsider all day, became a local hero to some of them when he stole beers from the facility s refrigerator and passed them around to the others.
