I cannot help but laugh at this illustration from the World Economic Forum's Global Gender Gap Report.
A brief glance at this graph and you would come away thinking, "Wow, there is a fantastic correlation between Gender Equality and World Competitiveness rankings! Look at that clustering around the median line!"
No kidding. Could this result be due to the fact that both rankings are compiled by the same organization, with one of the major classes of criteria used to determine the World Competitive Report rankings being measures of how effectively states make use of the talents of their female citizens?
The graph is a comparison of apples and apples.
Japan's rank, by the way, on the Gender Equality list is #93. Some folks are flabbergasted.
Maybe the ranking has something to do with this.
