academia - Voting on a crisis in China

Professor Ding Yuanfu of Beijing University has been polling experts on a possible major crisis in China, and a majority expects this before 2010, reports 'China Elections', noted by China Digital News.
Most likely it will be a social crisis, rather than an economic crisis. "Of the 77 experts who replied to the questions, 51 believed that a crisis with big consequences for China‘s economic and social development would happen. "
There is no indication on who those experts are, I only know that I was not included. I find democratic procedures very useful, but voting on a potential crisis seems a bit like fortunetelling, isn't it?
