I basically double majored in international affairs and economics but ultimately became a software engineer. I actually think both my courses of study were valuable. I’m basically self-taught as a developer (though I had mentors) and other than Comp Sci or Physics, there’s probably no other majors I’d pick as a base.

For international relations, it’s just always good to know about diplomacy and history. We had courses where we studied successful negotiations. The military history wasn’t so useful but there’s way more history made without guns than with them.

Econ is a good default major for a lot of fields. You learn to make statistical models and there’s strong math requirements with more of a focus on practical math than theoretical. (There’s even a little coding involved.) There’s classes on how businesses are run at a high level. Behavioral econ is helpful in small, but important ways (like designing little user interface nudges and prompts).

If I could redesign college, I’d make everyone in STEM majors do a minor in one of the humanities (and vise versa). We’d all be better off.
