| Abstract: | This paper explores the role of perceptions of the opinionsof others as they relate to the formation of public opinion.Two interrelated theories involving such perceptions, the thirdperson effect and the spiral of silence, are tested in the contextof public opinion regarding divestment of financial interestsin South Africa. As hypothesized by the third person effect, perceptions of theinfluence of media reports on others were found to be consistentlygreater than perceptions of influence on self. Findings werestrongly supportive of this component of the ‘third personeffect’ hypothesis. Perceptions of the opinions of otherswere also explored in relation to respondents' willingness toexpress their opinions publicly. As suggested by the spiralof silence theory, respondents were found to be more willingto express their opinions publicly when they perceived a trendin support of their viewpoint, or when there was a greater perceivedlikelihood of achieving success for their issue position. The size of the effect produced from joining these two processesis moderated by the role of issue salience. People perceivingdivestment as a highly important issue are more likely to ascribegreater media influence to others than to themselves, but theirwillingness to express their opinions publicly is least likelyto be influenced by perceptions of the climate of opinion. |
