I work as a Data Scientist, but my grad degree is in Political Economy. On the math/stats side I'm definitely weaker than some of my colleagues (and I appreciate their skill, and learning from them). But I often see people with much stronger math skills than myself make very critical errors when trying to make inference on data generated by humans.

I think a nice team can have some balance, with enough overlap that we can find common ground. I'd be uncomfortable without knowing I can rely on some of my peers on some of the heavier algorithmic or SDE stuff.
