Which global trends do leaders perceive as over- or underestimated

 Interesting survey in the latest 'Global Risk' report from the World Economic Forum:

Outlook on the Global Agenda 2011
 
The survey was asking 560 thought leaders accross the world on whether these trends will have an impact in the next 12-18 months, and whether this impact was either over or underestimated.

The result is quite striking, in that sustainability and climate change is seen as overestimated, but more societal trends like income inequality and the growth of youth population were seen as underestimated.
