A stranger is a person who is unknown or unfamiliar to another person or group. Because of this unknown status or unfamiliarity, a stranger may be perceived as a threat until their identity and character can be ascertained. Different classes of strangers have been identified for social science purposes, and the tendency for strangers and foreigners to overlap has been examined. The presence of a stranger can throw an established social order into question, "because the stranger is neither friend nor enemy; and because he may be both". The distrust of strangers has led to the concept of stranger danger (and the expression "don't talk to strangers"), wherein excessive emphasis is given to teaching children to fear strangers despite the most common sources of abduction or abuse being people known to the child.
Definitions A stranger is commonly defined as someone who is unknown to another. Since individuals tend to have a comparatively small circle of family, friends, acquaintances, and other people known to them—a few hundred or a few thousand people out of the billions of people in the world—the vast majority of people are strangers to one another. It may also more figuratively refer to a person for whom a concept is unknown, such as describing a contentious subject as "no stranger to controversy," or an unsanitary person as a "stranger to hygiene". A stranger is typically represented as an outsider, and a source of ambivalence, as they may be a friend, an enemy, or both. The word stranger derives from the Middle French word estrangier, meaning a foreigner or alien. The boundaries of what people or groups are considered strangers varies according to circumstances and culture, and those in the fields of sociology and philosophy in a variety of broader contexts. According to sociologist and philosopher Zygmunt Bauman, every society produces its own strangers, and the natures of "strangeness" is "eminently pliable [and] man-made". Alternatively, Lisa Atwood Wilkinson has written that "[b]y definition, whoever is a stranger to me is someone who is not a philos: a stranger is a person who is not related to me by blood or marriage, not a member of my tribe or ethne, and not a fellow citizen." Another asserts that "[i]t has been argued by many a philosopher that we are all strangers on earth, alienated from others and ourselves even in our own country".
Types of strangers
The state of being a stranger may be examined as a matter of degrees. For example, someone may be a partial stranger in cases where they are unable to communicate, or another is unable to understand aspects of an individual, their perspective or experiences. Alternatively, one may be a moral stranger to another who acts "out of fundamentally divergent moral commitments", even though the person may be a close friend or family member. A stranger with whom a person has previously had no contact of any kind may be referred to as a "total stranger" or "perfect stranger". Some people who are considered "strangers" due to the lack of a formally established relationship between themselves and others are nonetheless more familiar than a total stranger. A familiar stranger is an individual who is recognized by another from regularly sharing a common physical space such as a street or bus stop, but with whom one does not interact. First identified by Stanley Milgram in the 1972 paper The Familiar Stranger: An Aspect of Urban Anonymity, it has become an increasingly popular topic in research about social networks and technologically-mediated communication. Consequential strangers are personal connections other than family and close friends. Also known as "peripheral" or "weak" ties, they lie in the broad social territory between strangers and intimates. The term was coined by Karen L. Fingerman and further developed by Melinda Blau, who collaborated with the psychologist to explore and popularize the concept.
Strangers and foreigners A stranger is not necessarily a foreigner, although a foreigner is highly likely to be a stranger:
A foreigner, the dictionary tells us, is someone not from one's own country, while a stranger is someone who is neither one's friend nor acquaintance. Although they overlap, the two meanings are not synonymous: a stranger is often a foreigner, though not necessarily (he may live just around the corner); most foreigners are also strangers, though not necessarily (one can have foreign friends). Foreignness implies passports and questions of citizenship or national belonging, in addition to evoking personal feelings of acceptance or rejection (“how exotic, how foreign” or “foreigners keep out!”). Strangerhood can also involve legal status, but is generally more weighted toward the affective: the “stranger in our midst” is not always a foreigner; he or she may carry our pass- port and still be considered—both subjectively and by others—as not belonging, not “one of us” (or, from the stranger's point of view, “one of them”). According to Chris Rumford, referencing the work of sociologist and philosopher Georg Simmel, "people who are physically close by can be remote and those who are far away may in fact be close in many ways". With the conglomeration of populations into large cities, people now have a historically high propensity to "live among strangers". Adopting a statist view, strangers may be seen as a chaotic challenge to the order imposed and sought by the nation-state, which is then faced with the challenge of assimilating the stranger, expelling them, or destroying them. Although this view may overlook important issues of what authority defines the stranger, and how that determination is made.
Interactions with strangers Interactions with strangers can vary widely depending on the circumstances and the personalities of the people involved. Some people have no difficulty striking up conversations with strangers, while others experience strong discomfort at the prospect of interacting with strangers. At the opposite end of the spectrum, some people are excited by engaging in sex with strangers. Psychologist Dan P. McAdams writes:
