“Corruption” is defined by Transparency International (TI) as “the abuse of entrusted power for private gain.” Each year TI publishes a “Corruption Perceptions Index” which scores the world's nations out of ten for their public sector honesty and the just-released 2011 report paints a bleak picture. Only six countries scored 9.0 or better, and just 49 of the 186 countries assessed in the report scored better than 5.0. Analysis shows more than 80% of human beings on Planet Earth exist under regimes which score 4.0 or less. December 9 is World Anti-Corruption Day.
