Panic
? ?A panic is a form
of collective in which a group of people, face with an immediate threat, react
in an uncoordinated and irrational way. Their behavior is uncoordinated in the
sense that cooperative social relationships and beak down. It is irrational in
the sense that people’s actions are not appropriate for the goals they wish to
achieve.
? ?The progress of a panic follows a fairly typical
course. A sudden crisis occurs; people experience intense fear; normal social
expectations are broken; each individual tries desperately to escape from the
source of danger; mutual cooperation breaks down; and the situation becomes even
more threatening as a result. Panics are especially likely to occur in unusual
conditions in which everyday norms have little relevance, such as fires, floods,
earthquakes or military invasions. Some kind of response is necessary in these
situations, but there are few social norms that specify an appropriate reaction.
Thus, when a passenger aircraft makes a crash landing people may attempt to flee
before fire breaks out and cause an explosion, but there only succeed in
stopping themselves and others by creating bottlenecks at the exits. Awareness
of bottlenecks may lead to increased panic, with people fighting and trampling
one another in the effort to escape. Despite intensive training of airline
personnel in emergency evacuation procedures, a high proportion of passenger
deaths are caused by a panic that prevents people from escaping in time.
? ?The most dramatic panics are those that occur in situations of
extreme emergency, but not all panics are quite so frantic or short-lived. A
different form of this collective behavior is the financial panic, which is
typically provoked by rumor that the price of stocks will fall or that a bank
will be unable to repay its depositors. The classic example, of course, occurred
at the outset of the Great Depression in 1929 : as in other forms of panic, the
individuals involved tried to protect their own interests, and in so doing they
worsened the situation for themselves and everyone else. By trying to sell their
stocks as quickly as possible, people ensured that the price of stocks did fall;
by demanding their money back from banks, they ensured that the banks actually
did collapse. |
Which of the following is NOT TURE according to the passage?
A:All of the panics are caused by natural reasons. B:People get into panic possibly because of the rumor. C:In 1929, Americans worsened the Great Depression themselves to protect their own interests. D:Panics often cause a great loss in economy or human resources.
