Nomination Bench

Social network studies ask respondents to name peers, then spend months resolving those names to people. This bench resolves at collection time, while the one person who actually knows is still in the room, and it abstains instead of guessing. The panel on the right shows what that single choice does to the youth an intervention would recruit.

In the last 30 days, who did you talk with about staying healthy?

Up to five people. First names, nicknames or street names are all fine. Leave a row blank if there is no one else.

What the bench is arguing

The respondent is the disambiguating oracle

Resolving nominated names after fieldwork is a modelling problem. Resolving them during the interview is a question. Asking "which Mike?" costs four seconds and beats any posterior estimate, because the person who made the nomination is the only one who knows.

cf. Peer Disambiguation in Self-Reported Surveys using Graph Attention Networks, 2025

Abstention has to be a recorded state

Matched, ambiguous and unmatched are three outcomes, not two. Collapsing ambiguity into a best guess makes an unresolved nomination indistinguishable from a confirmed one downstream, and nothing later in the pipeline can recover the difference.

three states, never two

Resolution policy selects the intervention

Peer change agent selection runs on degree and position. Force-matching sends ambiguous nominations to whoever is already most named, which inflates the already-central and quietly changes the roster of youth an intervention recruits.

The unmatched row is a finding, not an error

A name no one on the roster carries usually means a real person outside the frame: a peer at another site, someone who stopped coming, an adult. Discarding those rows silently shrinks the network to the convenience sample and hides the boundary.

absent is not the same as missing
