I think this is a worthwhile study but also think we place too much emphasis on personality types. My wife studied primary (elementary) school teaching for 4 years and then was a teacher for over 6 years. After she became tired of the profession she was able to self-teach web dev for 9 months using Udemy and now has been working as a software developer for roughly a year now. Nominally a study like this might have put her into the caring profession box a few years ago but she is professionally ambidextrous, and likely other people surveyed will be too.
