Understanding the Pareto Principle (The 80/20 Rule) http://betterexplained.com/articles/understanding-the-pareto-principle-the-8020-rule/ Originally, the Pareto Principle referred to the observation that 80% of Italy’s wealth belonged to only 20% of the population.

None of the papers are linked to there, it's just a plain text list (Why Mr. Buzan? If you claim "Here's all the evidence you need!", don't you think that transparency is called for?). So WikIT has done the work for them by, as far as we can, gathering the links here for review. Mind mapping deserves academic backup as solid as that of concept mapping, assuming studies of a sufficient standard to provide evidence can be found, not just anecdotes. But before we look at that list, we need to consider "efficacy of mindmapping" for what? Mindmapping, as this wiki shows, is used as a tool in a wide range of activities. All the Buzan Online references focus on learning and memory with no mention of the use of mind mapping f...
