These norms provide stability in the long run, preventing the society from decaying into chaos, and ensuring that even monumental change happens slowly. But they also 5 strongly influence individuals to conform to society. For instance, one study in the 1950s showed this very clearly. New students at a university were randomly assigned to live among either conservative students or liberal students. The researchers observed that these new students gradually adapted their values and beliefs over time to fit the 10 norms of their surroundings. 2 Other studies have shown that people followed group norms even when they had direct evidence that contradicted the norm. For example, in one study, people were asked to estimate the length of a line drawn on a piece of paper. People's estimates followed a group norm Soini insmye daug goland that the group 15 even in cases when people could see with their own eyes was wrong. 301 10 aniq 3 Social norms often stifle creativity in groups. To the extent that creativity is the result of "thinking outside the box," groups do not normally reward creative individuals, but instead ignore them or 20 even push them out of the group completely. This often works to the businesses who strive to attract creative talent to detriment of many their organization only to see them become unproductive under the pressure of conformance to norms.

B You are a college student going to study in the US and need travel insurance. You find this review of an insurance plan written by a female international student who studied in the US for six months. 0 There are many things to consider before traveling abroad: pack appropriate clothes, prepare your travel expenses, and don't forget medication (if necessary). Also, you should purchase travel insurance. Imam gavo 0012 1ovo od 1200 sla When I studied at Fairville University in California, I bought travel insurance from TravSafer International. I signed up online in less than 15 minutes and was immediately covered. They accept any form of payment, usually on a monthly basis. There were three plans. All plans include a one-time health check-up. gisinal The Premium Plan is $100/month. The plan provides 24-hour medical support through a smartphone app and telephone service. Immediate financial support will be authorized if you need to stay in a hospital. It had the 24-hour telephone The Standard Plan worked best for me. assistance and included a weekly email with tips for staying healthy in a foreign country. It wasn't cheap: $75/month. However, it was nice to get the optional 15% discount because I paid for six months of coverage in advance. If your budget is limited, you can choose the Economy Plan, which is $25/month. It has the 24-hour telephone support like the other plans but only covers emergency care. Also, they can arrange a taxi to a hospital at a reduced cost if considered necessary by the support center. I never got sick or hurt, so I thought it was a waste of money to get insurance. Then my friend from Brazil broke his leg while playing soccer and had to spend a few days in a hospital. He had chosen the Premium Plan and it covered everything! I realized how important insurance is-you know that you will be supported when you are in trouble.
