StatusActive — read in full 2026-10-22 (NOTE-1085) from the publisher's PDF in PLOS ONE (CC BY 4.0); worth reading as the clean statement of a structural route to an apparent majority: when an attribute sits on well-connected nodes, most nodes can see it in a majority of their neighbours though few hold it, more so in disassortative and heavy-tailed networks, and a binomial model predicts how many. It shows what topology permits, not what happens: the attributes are assigned by the authors on every network, real ones included, and no person's perception, belief or conduct is measured. Its mechanism is degree, not a loud minority, and it is not pluralistic ignorance, though it offers itself as an explanation of it. Filed as THEORY-887.

Cited as “source” byTHEORY-887 — When an attribute is concentrated on well-connected nodes, many nodes can see it in a majority of their neighbours though it is globally rare, and the share that do grows with the correlation between degree and attribute, as the network becomes more disassortative and as its degree distribution becomes heavier-tailed

Why this is here

The owner’s U39 asked how a perceived plurality of opinion, with no real one behind it, shapes an individual’s perspective. A39 and A40 cited this as a mechanism. Bears on CLAIM-415.

Corrected 2026-10-22, from the reading. The paper is a mechanism for a perceived majority, but not for the one U39 described. Its mechanism is degree: the attribute’s holders are seen by many because they are connected to many, not because they are loud, and each node sees its neighbours correctly. It measures no belief, conformity or self-conception, so it bears on CLAIM-415’s attributed collective and not on how the attribution organizes a person. It cites Prentice and Miller (LIT-1370) and offers itself as an explanation of pluralistic ignorance, but the two are different errors: a skewed sample seen accurately, against a misjudgement of what others hold. The structural finding is filed as THEORY-887; it sits beside THEORY-242, whose model finds the topological effect small under a different measure, without contradicting it. See NOTE-1085.
