There might be a correlation, but I doubt causation. I would argue people with ADHD, like myself, tend to end up in situations where extreme pressure and chaos is more common. Thus, we have more exposure than the average person. I imagine it can be a trainable trait in many people.

Yeah, I think this is the key point. I am better at handling chaos because I grew up around chaos (my mom has adhd and so do I) so I am much better at handling things falling apart.
