Polarization as a function of meaning and consequences

Studied the effect of meaning and consequences on shifts toward extreme judgments (polarization) as a result of group discussion. Since it was hypothesized that high levels of both meaning and consequences would activate pressures to conform to the appropriate cultural norm, greater polarization was predicted under those conditions. Consequences were varied by asking subjects how willing they were to participate in another actual (high consequences) or hypothetical (low consequences) experiment. Meaning was varied by information that the proposed experiment would have high or low social and scientific significance. Sixty male college students discussed their preferences in three‐person groups. Prediscussion, consensus, and postdiscussion scores were obtained; the critical polarization scores were computed on the basis of individual's movement away from the prediscussion mean of their group. Partial support for the hypotheses is provided by a cross‐over interaction (p < .05) in changes from the prediscussion to consensus scores, which indicate greater polarization in the high‐meaning, low‐consequence condition, and in the low‐meaning, high‐consequence condition. The results are discussed with respect to their implications for research in which subjects do not expect real consequences to follow from their statements of opinion.
