Callarman stated, First, things are changing so rapidly that what you hear today may not be true tomorrow. Second, the people who answer the surveys may tell you what they think you want to hear, rather than what they really believe (T. E. Callarman, Some Thoughts on China, Decision Line, March, 2006, pp. 1, 43 44).
