I just read somewhere that the Nords are the second smartest human race in tamerial. That doesn't make sense how can they be smarter than imperials and redguards if their just a bunch of stupid drinking barbarians. And throughout are history barbarians in the dark ages were always stupid. And also their suppoused to be really strong so doesn't that usually mean that their suppoused to be stupid. And when I talk to Nords in oblivion their so [censored] stupid, like Jayred ice veins in the shivering isles goes "They say the gate keepers magic, well I don't believe in magic!!!" I mean how can walking skeltons and a giant inhuman monster conivince you theres no such thing as magic.
I have never seen any documentation either ingame or on TIL which indicates that Nords are inherently more stupid then any other race. Instead I've found that, like the rest of the races, intelligence varies on a case-by-case basis. The reason for so many "stupid" Nords is probably because the devs like to use the "drunken barbarian" stereotype to inject some humor into the game and, unfortunately for the Nords, they're really good at playing barbarians.
As for Jayred Ice Veins, well, he was in the Shivering Isles which means he was probably insane.
If this is made up, I lol.
I may add something about their Aryan purity, just to see how it fits and if anyone notices.
Nords do have an affinity of sorts with vocalized sounds. For proof, look up the Thu'um at TIL.
