0.) some people have been historically advantaged over each other for non-meritocratic reasons.

1.) one of the ways people have been advantaged is itself in the notability of their actions.

2.) Therefore, using notability as a prerequisite for inclusion perpetuates a non-meritocratic historical bias.
