First of all - I wouldn't count being a businessperson as liberal arts.
One way you can look at it is how many people drop out of technical subjects because they find them too hard to move to humanities and liberal arts vs. the opposite. Anecdotally, for me the former number has been much larger. The latter number has been 0.
Similarly, I've had many technical friends who took liberal arts courses and generally did very well in them. I also have many liberal arts friends who took technical courses and did not do well in them. In addition, the technical people I've met have been much much more hard-working than liberal arts people. (An exception I'd make is creative arts - people I've encountered in that field have generally been extremely hard-working. Also no one I've met has moved from say math to music because they found math too hard.)
Now it might just be because liberal arts people just don't like the technical subject matter on average as much as technical people like the liberal arts subject matter. But even if that's true, one is then right to choose technical people over liberal arts people.
Lastly, I also know liberal arts majors who are smarter than many technical folk I've encountered but I'm talking about the general trend here.
