A self-claim is a statement a person makes about oneself, or that an entity makes about itself. Living Platform for instance contains many such claims which should link to Living Platform itself rather than the Living Platform page.

Likewise, if you are making a self-claim you should link it to your user page rather than to your wiki bio unless it is somehow related to the bio and not to your own self-image.

One cannot self-organize easily unless self-claims are clear. See being for more on the way self-claims tend to define "a being".
