    Are you shy? If you are, you are not alone. In fact, close to 50 percent of people are shy. Almost 80 percent of people feel shy at some point in their lives. These days, shyness is becoming more and more common. Now scientists are trying to understand shyness. They have some interesting ideas about why people are shy.

Is it possible to be born shy? Many scientists say yes. They say 15 to 20 percent of babies act shyly. These babies are a little quieter and more watchful(小心提防的) than other babies. Interestingly, these shy babies usually have shy parents. As a result, scientists think that some shyness is genetic.

Family size might lead people to be shy as well. Growing up alone, they often play by themselves. They are not able to learn the same social skills as children from big families.

You may also be shy because of where you were born. When scientists studied shyness in different countries, they found surprising differences. In Japan, most people said they were shy. But in Israel, only one of three people said so. What explains the differences? One scientist says the Japanese and many Israelis have different opinions of failure. In Japan, when people do not succeed, they feel bad about themselves. They blame(责备) themselves for their failure. In Israel, the opposite is true. Israelis often blame failure on outside reasons, such as family, teachers, friends or bad luck. In Israel, freedom of opinion and risk taking are strongly supported. This may be why Israelis worry less about failure and are less shy.

For shy people, it can be difficult to make friends, speak in class, and even get a good job. But scientists say you can get over your shyness. They suggest trying new things and practicing conversation. And don’t forget, if you are shy, you are not the only one.
