In theory, we make decisions on the basis of high expectation of yields with low deviations. Risks should be evaluated before the project is put into effect. Bullet trains surely have brought about some benefits such as the global reposition of Chinese high technology and the showing off of the Chinese advanced manufacturing industry. However, many low-income civilians, for example, migrant workers, are unwilling to choose the new mode of transportation because they don’t think it is worth spending so much on fares for the not so necessarily high velocity. Maybe profit is not so good as expected, for bullet trains are not so welcomed and hence become popular among ordinary civilians. Besides, train delays and accidents bring some suspects on the problem of safety. To compromise a little on the speed and lower the cost may be a wise choice. On one hand, it increases the confidence on the safety of the train, and on the other hand, it will be more welcomed by citizens and may bring more passengers, thus increase profit or incur sentiment of happiness in the public.
As for the nuclear power plants, if it were not for the Japanese tragedy, most of us would think it was an acceptable means to provide power as it had been taken into usage for many years without big accidents. From the point of halo effect, for the moment most of us surely don’t want to take the risk of giving life to exchange for power, no matter how important that has been to our daily life and to our modern industry.
What is risk? The possibility of results that deviate from what we have expected and may bring about negative impacts. Nothing is for sure, but to determine in what degree to accept the risk is troublesome.
