Controller - your charts are really meaningless without normalizing based on the general population. You're surprised at how even the distribution has been, but that in itself is significant since, for example, INTJs are less than 1%of the population. The fact that INTJs are about as common here as other personalities either means that they're MUCH more likely to wake up, or that they're much more likely to talk about it online, or some combination thereof (I'm in the "combination of the two" camp).The chart I think you are reffering to was showing how common the different letters where, E VS I, N VS S, etc.
In my last comparison between the different types, I took how common they are into consideration. And I made the point you just made.
