Most Jewish girls are smart BH.
OT/PT and Speech are what most girls go into because, frankly, they do not demand a lot of creativity and intensity, they involve a lot of memorizing and patience. The actual job, once learned, does not change that much.
Getting a doctorate, going into the sciences, or earning law degree is something only an exceptionally intelligent girl will attempt, someone who enjoys challenging mental work, and many such girls are also very frum and know halacha well. It’s easy to see how a 22 year old yeshiva boy with little education would be intimidated!
Also, I think it’s good to have some weaknesses and be aware of them. I personally thank Hashem for my very minor weaknesses (auditory stuff, organization, finances) because it will make it very easy for me to look up to my husband!
