Majority/ Minority Size and the Evaluations of Persuasive Arguments

The present study examines the influence of relative minority size on perceptions of argument quality and attitude change. Strong and weak arguments for both cautious and risky positions were presented in conjunction with information describing the size of minority factions as either small or large. Results demonstrated that cautious argument quality influenced perceptions of argument quality only when the majority advocated a cautious position or when the minority faction was large. Results are discussed in light of their implications for normative and informational influences in group polarization.
