Are you afraid, to raise your hand in class, even when you know the answer? If you are, most people would say that you are shy. If you feel shy, you are not alone. Nine out of ten people are at least a little shy. But however shy you are, scientific evidence seems to show that it isn’t your fault. You may have been born that way.
     How do psychologists measure shyness? One way is by observation. They keep detailed records of people’s actions—like how often these people speak to others, or how long it takes someone to say "Hello" to a stranger. Another way to measure shyness is to ask people questions. The test only takes about 10 minutes. It asks question like "Do you like going out a lot?" and "Do you have many friends?" People must answer either "Yes" or "No". These questions can predict how people actually behave in social situations. Suppose the test tells you that someone is shy. Chances are good that person will act shy.
    When scientists measure shyness, they are really comparing degrees of shyness. In other words, when researchers say people are shy, they really mean they are more shy than others.
