«Disclaimer

This article is my PERSONAL OPINION about the state of the affairs in the software engineering field. This is not intended to be a scientific paper so many statements are intentionally bold and direct to make the text short. I did my best to point the psychological reasons of software project failures based on my own observations and available sources, but I am not a professional psychologist nor statistician and I am PROBABLY TOTALLY WRONG. Additionally I have no data to back these statements, so treat it with a dose of scepticism.»
