Minority influence
A small, consistent dissenting voice can slowly convert the majority.
What it means
The process by which a numerical minority changes the attitudes or behavior of a majority, not through pressure to comply but by prompting genuine private reconsideration. Consistency over time is the decisive factor: a minority that holds its position firmly yet flexibly, without appearing rigid or self-interested, signals confidence and forces others to attend to its message. Unlike majority influence, which tends to produce fast, public, surface compliance, minority influence works slowly and often indirectly, yielding deeper, internalized, and sometimes delayed conversion. It matters because it explains how social change, innovation, and reform originate from committed few rather than the many.
Examples
In Moscovici's studies, a consistent minority calling blue slides 'green' led some majority members to shift their own color judgments.
One engineer keeps raising the same safety concern, calmly and with the same evidence, meeting after meeting; a year later the design has quietly changed and nobody credits her.
A lone juror who states her doubt consistently and without hostility can push the others to reread the evidence and genuinely change their minds, rather than merely humour her.
First described in Serge Moscovici (1969, 1980).
