The Scots who play rugby and soccer are actually relatively wise to most of their counterparts. Of course, this is not saying much in terms of soccer, and in both cases their main problem is that they are just hopelessly incompetent. As for the politicians, yes they are exceedingly foolish, but fortunately, they do not have that much authority under the current constitution.
Vis a vis the other areas, I'd agree with golf (but again that's not any great accomplishment when you compare it to the alternative....) but demur on finance (once quite good, but today--outside of the Royal Bank of Scotland--a shambles) and engineering (great history, shaky present, very uncertain future).
I, for one, am glad that golf is the one of these disciplines that continues to prosper!
