Probably because it’s much harder for adults to change their identities. They have lives, responsibilities and dependants. Unlike children they can’t change their identities on a whim without repercussions, or negative impacts on people they care about. I imagine that many people would rather ignore their “true” identity, than risk losing a spouse they care about, or disrupting their children’s futures.
