Socio Sexual Hierarchy in the Hundred Acre Woods
Alpha:
"natural self-confidence and strength of character"Christopher Robin. He is on top of the world, not threatened by toys and woodland creatures, though if there were other boys in the stories, we would see him in competition. Tigger is an Alpha of the carefree variety.
Beta:
"the lieutenants, the petty aristocracy"Rabbit from the books. Rabbit knows how to get things done. He takes very good care of his friends-and-relations. He understands the hierarchy and his place in it.
Delta:
"the great majority of men"Winnie the Pooh. Owl, perhaps, though he has some Gamma tendencies.
Gamma:
"the obsequious ones, the posterior puckerers, the nice guys who attempt to score through white-knighting, faux-chivalry, flattery, and omnipresence"Piglet
"Gammas who find themselves in charge almost invariably behave like petty, micromanaging dictators; Gamma male behavior is very similar to normal female behavior in a lot of ways."Rabbit from the Disney abominations. When he thinks he's in power, he's a petty tyrant.
Omega:
"the losers.... That which doesn't kill them can make them stronger, but most never surmount the desperate need to belong caused by their social rejection. ... [T]he pain of their constant rejection renders the suffering of others completely meaningless in their eyes."Eeyore from the books.
Sigma:
"the lone wolves"Heffalumps. Possibly also Woozles.
