I think mentally we're perhaps a bit more German than our neighbors. Hitler for example (supposedly) said Norwegians are the purest Aryans, but they're unruly compared to the orderly society of Germans.
Swedes are like a breed of a more balanced temprament between chill and orderly, we don't go full German so to speak, but subconsciously are very consensus minded.
The Folkhem idea also shaped society to become more equal and homogenous in many ways.

Also, practically everyone grow up with the same movies and children's programs. All the Astrid Lindgren books/movies, Sällskapsresan, Donald duck and friends on Christmas etc. help shape a collective image of Sweden and being Swedish.
