A psych major with strong statistical training-- a consumer products company can train that person in various market research techniques even if he/she had no exposure to marketing whatsoever.

I’ve hired sociology majors, poli sci majors, etc. for various entry level HR roles. They need to be able to interpret graphs, charts; write a coherent 5 page summary of a 300 page report, look at a variance and break down what the relevant factors are i.e. the things a strong sociology or poli sci major knows how to do.
