Spoilt for Choice
Choice,we are made to believe,is a right. In daily life,people have come to expect endless situations
about which they are required to make decisions one way or another. In the main,these are just annoying
moments at work which demand some extra energy or brainpower,or during lunch breaks like choosing which
type of coffee to order or indeed which coffee shop to go to.But sometimes selecting one option as opposed to
another can have serious or lifelong consequences.More complex decision-making is then either avoided,
postponed,or put into the hands of the army of professionals,lifestyle coaches,lawyers,advisors,and the like,
waiting to lighten the emotional burden for a fee.But for a good many people in the world,in rich and poor
countries,choice is a luxury,not a right. And for those who think they are exercising their right to make
choices,the whole system is merely an illusion,created by companies and advertisers wanting to sell their
wares。
The main impact of endless choice in people's lives is anxiety.Buying something as basic as a coffee pot
is not exactly simple.Easy access to a wide range of consumer goods induces a sense of powerlessness,even
paralysis(瘫痪),in many people,ending in the shopper giving up and walking away,or just buying an un-
suitable item that is not really wanted in order to solve the problem and reduce the unease.Recent surveys in
the United Kingdom have shown that a sizeable proportion of electrical goods bought per household are not
reilly needed.The advertisers and the manufacturers are,nonetheless,satisfied.
It is not just their availability that is the problem,but the speed with which new versions of products
come on the market.Advances in design and production mean that new items are almost ready by the time
that goods hit the shelves.Products also need to have a short lifespan so that the public can be persuaded to
replace them within a short time.The classic example is computers,which are almost outdated once they are
bought.At first,there were only one or two available from a limited number of manufacturers,but now there
are many companies all with not only their own products but different versions of the same machine.This
makes selection a problem.Gone are the days when one could just walk with ease into a shop and buy one
thing;no choice,no anxiety.
The plethora(过剩)of choice is not limited to consumer items. With the greater mobility of people
around the world,people have more choice about where they want to live and work一a fairly recent phenome-
non.In the past,nations migrated across the earth in search of food,adventure,and more hospitable environ-
ments.Whole nations crossed continents and changed the face of history.So the mobility of people is nothing
new. The creation of nation states and borders effectively slowed this process down.
Which of the following best expresses the writer's view on choice?
A.Better more choice than no choice.
B.Better no choice than more choice.
C.All choice is easy.
D.More choice,more anxiety.
