In a coment, David Richerby pointed out that in his university in the UK everybody was entitled to attend to any lectures, except for Medicine. I have also found that Dusseldorf has the same policy, but no reasons are quoted.
I can think of two possibilities:
- Potential missuse of the information in the class "oh, I saw a rash like that the other day, it is nothing". (But no one has died because "the condition number of that matrix is not SO bad...").
- Sensitive information, like some details about patients, necessary for the education.
But they don't seem too strong. They would both apply to med students, or just people that signed up for a few courses, but are not going to be doctors (think some biologist that may be interested in taking Pathology).
Does anyone know of an official reason for this policy?
