To the Editor.
—We read with amusement the letter by Drs Shulkin and Bari1 in the September issue of the Archives concerning deteriorating vision as a risk of attending medical school. Their argument seems to boil down to: medical students tend to do a lot of reading: a lot of reading tends to cause myopia (sic?); therefore, medical students tend to become myopic. Having been myopic and medical students, we really favor the following sequence: myopes like to do a lot of reading; medical students do a lot of reading; therefore myopes tend to become medical students. However, you may prefer this sequence: myopes tend to have a higher IQ than the general population; so do medical students; therefore myopes tend to become medical students (or vice versa, if you like).A course in logic is sometimes preferable to one in statistics.
