Apparently you didn't understand my post clearly. .
Apparently I didn't.
To me, the two go hand in hand: Testing and Rank....(and yes, higher up there are recommendations - but in my experience those are conditional based on age, health, etc.....) - so sorry for the misunderstanding.
To be honest, in my experience, ego comes with the person, not the rank. If they brag about their rank, they would have bragged at 5th kyu as well as at 5th dan....and those kind of people brag about a lot more than just their rank! (IMO, of course)
