To sum up, shyness has both environmental and genetic causes. Some people come into the world shy. Others become shy as a result of their experiences in life. It appears that most people have experienced shyness at some time in their lives, and research indicates that the number of shy people is increasing. Therefore, if you are shy, you have a great deal of company
In addition, close to 80 percent report having felt shy at some point in their lives'' (54).  As shyness is so common, it is not surprising that social scientists are learning more about its causes. They have found that shyness can result from both biological and environmental factors.
In fact, in Your Child’s Communication Skills, Jim Henderson and Lydia Zimbardo have found differences between sociable and shy babies that show up as early as two months. In one of their studies, two-month-olds later identified as shy reacted with signs of stress to moving mobiles and tape recordings of human voices. These shy babies had increased heart rates as well as jumpy movements of arms and legs, and they cried a great deal (59).
Furthermore, parents and grandparents of shy children often say that they were shy as children. They report childhood shyness more frequently than parents and grandparents of non-shy children.
A second environmental cause of shyness may be one’s culture. In a large study conducted some years ago in several nations, 40 percent of participants in the United States rated themselves as shy. This percentage is compared to 57 percent of participants in Japan and 55 percent in Taiwan. Of the countries participating in the study, the lowest percentage of shyness was found in Israel. The rate there was 31 percent (Environment 130). 
However, environment can, at least in some cases, triumph over biology. On the one hand, a shy child may in time lose much of his or her shyness. On the other hand, many people who were not shy as children become shy as adults. Both facts point to environmental causes. 
Henderson and Zimbardo note that differences “in the way each culture deals with attributing credit for success and blame for failure” may account in part for the higher rate of shyness reported in Japan than in Israel. In Japan, failure is generally attributed to the individual but success is not, while the reverse is true in Israel. Therefore, Israelis may be more likely to take risks than the Japanese (101).
The first environmental cause may be the child’s home and family life. Children who grew up with a difficult relationship with parents or older siblings are more likely to be inhibited in social interactions. Another factor is that today’s children are growing up in smaller families. They have fewer relatives living nearby. 
Recent research shows that some individuals are born shy. Indeed, Mel Jones and Alena Plotz confirm that between 15 and 20 percent of newborn babies have signs of shyness (90). These babies are quieter and more watchful. 
Also, more children are growing up in single-parent homes or in homes in which both parents work full time. These children may not have frequent visits by neighbours and friends. Because they have less interaction with relatives and other visitors, they may begin to feel shy when they start school (Henderson and Zimbardo 130).
While being shy has some negative consequences, it has positive aspects, too. For example, shy people may be better listeners. Furthermore, Benton asserts that shy individuals are very productive in terms of work and relationships: “Because of their tendency toward self-criticism, shy people are often high achievers, and not just in solitary activities such as research and writing. Perhaps even more than the drive toward independent achievement, shy people long to make connections with others, often through altruistic behavior” (“Timidity” 250).
Adults, too, are becoming more isolated as a result of technology. Face-to-face interactions are no longer necessary in many situations. Instead, people can use machines to do their banking, fill their gas tanks, order merchandise, take college courses, and make friends. As a result, people have less opportunity to socialize in person. Therefore, they become more awkward at it. Eventually, they may start avoiding it altogether. In short, they become shy.
