Hi, i'm new here, but there's a question that i'm trying to answer and it would be great if some of you people with expertise could help me.

Here is a link to the wiki page for the un human development index, so you know what i'm on about:

Human Development Index - Wikipedia, the free encyclopedia

Essentially, I was wondering if the best performing countries on the UN's human development index have a different distribution of MBTI types in the population than relatively worse performing countries. I've got no hypothesis about whether they do or not, I just want to find out. Has anyone even done a survey of the distribution of different types in different countries? Anyone know how I could get the data from a bunch of different studies and put them into a bigger sample?
