Descriptive presence can affect trust, agenda attention, and the range of experiences inside an institution, but resemblance does not dictate policy choices. Members who share a characteristic can disagree about group interests, while members from different backgrounds can become effective advocates through consultation and coalition building.

Substantive representation requires evidence of action: sponsorship, voting, negotiation, oversight, or resource decisions aligned with a group's interests or expressed preferences. A photograph of the chamber establishes composition; it cannot establish whose priorities members advanced.

The relevant group and outcome must be specified. A delegation may descriptively mirror a state by gender but not occupation, and may substantively represent one policy concern while opposing another. Avoid treating either form as an all-or-nothing quality of an officeholder.
