Isn't that what an index fund is? "Undeclared" stock - you'll get whatever the average of the market is buying.

Just because they're an undeclared major doesn't mean they're not learning anything. You still take courses for those first two years - you just don't know what they're leading up to. It's not all that unlike founding a startup knowing that you'll have to pivot to get to a viable product.

(I was a de facto physics major for my first 3 semesters, switched back to being actually undeclared for my 4th (flirting with philosophy and sociology majors in the process), actually declared as a physics major in my 5th, and then switched to a CS major in my 8th and last. Just because you think you know what you're doing doesn't mean you actually do.)
