Note. Each genre of communication may exhibit all contexts, contents, and functions in this table (e.g., rumor also functions to impart cultural mores and gossip also functions to help the group make sense of ambiguity), though each genre’s quintessential contexts, contents, and functions are listed here. Rumor activity in ambiguous contexts therefore functions to make sense; it is a response to the core human motivation to understand (Fiske, 2004). The resolving of ambiguity is always a sense-making explanation of events that are unclear for some part of a group or community. As G. W. Allport and Postman put it in their seminal text, The Psychology of Rumor, “in ordinary rumor we find a marked tendency for the agent to attribute causes to events, motives to characters, a raison d'etre to the episode in question” [italics in original] (1947b, p. 121). Explanations primarily attempt to make reality perceptible and mean- ingful (Antaki, 1988); rumors are a collective effort at such explanations when a group—or subset of a group—is faced with uncertainty (Di- Fonzo & Bordia, 1998). To some extent, these explanations must pass some group norm of plausibility. When group standards of plausibility are high, rumor discussions look very much like fact finding. When the group standards are low, rumor discussions look very much like contagion or panic. Rumor is thus part of “normal collective information seeking” [italics in original] (R. H. Turner, 1994, p. 247) wherein the group is trying to define an ambiguous situation with a “lower degree Note. UM/H = low, medium, or high.

Effects are in decreasing order by the percent- age of respondents (n ranged from 66—73) who had ever observed the effect in their overall experience. Mean severity ratings are on a scale in which 1, 2, and 3 indicate small, medium, and large average effects, respectively. F indicates an external ramifica- tion, A indicates effects related to internal attitudes, and B indicates effects associated with internal behaviors (see text).

Our experienced sample had observed a large majority of the effects during their long tenures; each of the top 11 effects had been witnessed by at least 78% of the sample. The most commonly experienced— 90% or greater—rumor effects included detrimental consequences for employee morale, press reports, productivity, stress levels, and trust held by employees and customers. Effects were rated, overall, as moderately severe: 13 of the 17 effects were given an average severity rating between 1.50 and 2.50 (indicating medium severity). The most severe of these—those with an average rating at or above 1.75— Note. N = 63. Printed values are multiplied by 100 and rounded to the nearest integer.

Second, contrary to the MUM effect, when the rumor was about the ingroup and the recipient was a member of the ingroup, both positive and negative rumors were equally likely to be transmitted. In other words, participants did not hesitate to transmit negative rumor to an ingroup recipient. We expected the fact-finding motivation to underlie this effect. To test this idea, we conducted a mediation analysis that tested the effect of rumor recipient (ingroup vs. outgroup) on likelihood of transmission, when the rumor was negative and about the ingroup. We predicted that participants were more likely to transmit a negative rumor about the ingroup to ingroup recipients (as compared with out- group recipients) because they wanted to know if the rumor was true. Our prediction was partly supported: The effect of rumor recipient on likelihood of transmission was partially mediated by the fact-finding motivation.* Self-enhancement motivation in conditions of positive versus negative rumor about the ingroup or the outgroup when the recipient is from the ingroup or the outgroup.

Choices included a “don't know” op- tion, however, which garnered between 35% and 77% per question (M = 52%), thus limiting the 82% accuracy figure to those responses for which the employees felt “reasonably” certain of their answers (Walton, 1961, pp. 48-49). ‘Prasad (1935) presented a “representative set” of 30 rumors, 23 of which were verifiable (i.e., dealt with empirical as opposed to metaphysical events). of 244 rumors.’ One hundred thirty-seven rumors were true; 107 were false. To assess more closely the types of change occurring in true and false rumors, we computed the frequency of the verity-precision combinations for this sample; these are presented in Figure 6.2. The results are very similar to those of Student Survey 1. We first observe that the overwhelming majority of rumors were all or mostly true or false; there appeared to be little middle ground for rumors that had since been proven true or false. Of the all or mostly true rumors recalled, most by far resembled converts. Of those that proved all or mostly Note. ST = serial transmission. Note.
