I've also heard this described as "Engineer's Disease": "We think because we're an expert in one area, we're automatically an expert in other areas." (https://news.ycombinator.com/item?id=10812804).

I think the core lazy assumption that enables is the idea that all the other fields are properly understood as just like your field. Sometimes it's so bad that a software engineer will outright dismiss the ideas of actual experts as misguided, and insist on some "disrupting" the fields with some half-ass software-thinking.
