Person-affecting view

A person-affecting or person-based view (also called person-affecting restriction) in population ethics captures the intuition that an act can only be bad if it is bad for someone. Similarly something can be good only if it is good for someone. Therefore, according to standard person-affecting views, there is no moral obligation to create people nor moral good in creating people because nonexistence means "there is never a person who could have benefited from being created". Whether one accepts person-affecting views greatly influences to what extent shaping the far future is important if there are more potential humans in the future. Person-affecting views are also important in considering human population control.

A weaker form of person-affecting views states that an act can only be bad if it is bad for some existing or future person.

Person-affecting views can be seen as a revision of total utilitarianism in which the "scope of the aggregation" is changed from all individuals who would exist to a subset of those individuals (though the details of this vary, see the section below).

Some philosophers who have discussed person-affecting views include Derek Parfit, Jan Narveson, John Broome, Jeff McMahan, Larry Temkin, Tatjana Višak, Gustaf Arrhenius, Johann Frick, Nick Beckstead, and Hilary Greaves.
