I’d guess these effects are largely not causation, but correlation caused by conscientiousness/ambition causing both double majors and higher earnings.
Unless you’re certain of this or have some reason to suspect a factor pulling in the other direction, this still seems to suggest higher expectation from doing a double major.
I definitely agree, especially considering that double majors aren’t even that hard if you plan ahead. (For instance, you can major in math and management science while doing less units than the minimum allowed.)
I’ve edited the original post with a table on good major/minor combinations.
