it's very weird when people take correlation and present it as causation. I feel there are at least few steps in statement that people with that gene mutation are more susceptible to burn out. Like people with that gene mutation "like to be independent", "like variety", and therefore lack of those in regular 9-5 software development leads to burn out. How it is presented as a causation has only one practical application. Gene xyz is bad, don't hire people with gene xyz.
