Dear Huw,

Thank you for your relevant question; I don't see it as criticism at all. There should be no dogmas in science.

Your statement is right, NT types are abundant among software developers. But ST types are even more prevalent. Given that there are more ST than NT types among the general population, the percentage of NT software engineers stands out.

Nevertheless, there are significant discrepancies in the distributions and percentages of software engineers across the 16 MBTI types. Moreover, the software engineering profession has diversified enormously in the last 20 years, compared to mainly computational programming of 30-40 years ago, thus attracting myriad types of people performing specialized jobs. Those discrepancies tend to be exacerbated.

Now, trying to answer your question....
I am an advocate for cross-disciplinary research and borrowing perspectives from other areas, which give us the potential to address important issues in software engineering, thus should be encouraged. Please take a look at:

However, when it comes to human beings, things get really complicated.
Psychology is there to help us.

Thank you for sharing your work, Luiz.

It's interesting that MBTI remains a strong typological schema. If I recall my MBTI distributions correctly, the high percentages of "NT" personalities represents an impressive concentration.

Perhaps for the sake of this quiet list-serve, are you able to elaborate on a question I was considering whilst skimming your paper, please. In your final considerations, you (collectively) write:

"the amount of research on the effects and influences of personality in the field is relatively small. The evidence is weak and in many cases inconclusive. More research is required if we want results that can influence the practice of software development."

My question is, what influence does personality research in the contexts of various practices have, i.e. are there examples of transformative contributions? I have witnessed personality-based knowledge being usefully applied at an interpersonal (consulting) level, but the impression I have is that perhaps you have something broader in mind (such as interviewing for personality types etc)?

I intend no criticism in the question, I'm merely curious.
