This lends credibility (the graph) to something I've always suspected, ESFJ's tend to be dumb. Before anyone argues, intelligence within each personality type is a bell curve. If you have less people at the top, it means the average is lower, or the standard deviation is lower, or both. So either they are dumber on average, or they are more average on average, or both. Why do I care? Just a random thought I had.
