Estimating a student's likelihood of changing major and implications for college selection

My daughter is interested in two not-overly-common majors, and the fields are pretty different from each other.

I was happy to use this as a first cut for colleges to consider, because I figure any school that has both of those will have lots of other interesting stuff for her to choose from should she change her mind down the line.

(Neither of them are competitive-entry majors, though, at least not at the schools remaining on her list. That would throw the entire line of reasoning into a mild panic.)
