P UBLIC OPINION ANALYSIS has developed in the past two decades more as a set of effective polling practices than as a scientific theory. Polling has effe tively described a public's opinions and in some cases, succeeded in predicting public behavior. An underlying theory, however, has lagged behind polling in development. All too often a "theory" has been expressed in terms of vague verbal definitions and partial descriptions. Discussions of public opinion have also tended to specialize on political or consumer opinions, or on other special fields. A scientific theory of opinion, however, must encompass the full scope of opinion including all activity and all preparatory adjustments for any behavior studied in the social sciences. Public opinion research has lacked a theory to guide its growth into new realms with increasing precision and power of prediction. The warp of practice and the woof of theory need to be woven together into a more useful fabric of opinion research. This paper attempts to develop a more adequate theory of opinion. The following specifications will be followed here as a guide: "Any scientific theory should offer a predictive system of tested principles or testable hypotheses which specify relations among operationally defined variables." These specifications will be discussed with reference to our theory in this paper. THE FRAMEWORK OF THE MODE-TENSE THEORY OF OPINION The mode-tense theory deals with two important dimensions of human behavior. (1) A respondent's answers about his behavior are classed into the past, the present, and the future tense of time, (relative to the moment of answering). (2) The mode-tense theory specifies that each of the three tenses be subclassified by the three "modes" of the respondent's speech behavior as defined by his using the words "I feel . . . ," or "I know . . . ," or "I do. . ." The feeling, knowing, and doing modes of behavior are operationally defined This content downloaded from 158.143.233.108 on Wed, 03 Jun 2020 19:24:20 UTC All use subject to https://about.jstor.org/terms 572 PUBLIC OPINION QUARTERLY by the poller recording the exact words of the respondent in response to questions which attempt to isolate these modes. In polling, what the polled respondent says he does is often taken to indicate what he actually does. This assumes a high validity correlation between speech and action, between poll response and "life" response. This validity correlation can be improved under poll conditions which get the fullest possible comprehension, articulateness, sincerity, and cooperativeness from the respondent. The mode-tense approach is designed to facilitate these conditions. Since speech behavior in a poll (which might be called "opining") is a verb, this variable can vary in all the grammatical ways there are for con- jugating verbs. It can vary in person and number, in tense, voice, and mood. This varying is controlled by asking the questions so as to get answers in the first person singular, present tense, active voice and indicative mood. The answers are some variant of the ideal type: "I opine. . . ." Then, by tabulating for all persons in the poll, the distribution of that population's opinion on that question is determined for that date. "Polled public opinion" is thus here defined as the distribution of polled responses. The questions asked and the polling technics and conditions complete the operational definition. This should be called "polled opinion," letting the term, "popular opinion" mean opinions of the populace determined in other ways. The term "public opinion," then, may mean either or both the polled or the popular opinions. Whenever the poll questions ask about attitudes, the verbalized response is here defined as "an opinion" in the narrower sense. An opinion is the assertion of an attitude. "An attitude" in turn is defined as preparatory behavior, a readiness to respond in a certain way toward an object whenever the external situation is appropriate. This behavioristic definition of opinion as the verbalizing of incipient and covert behavior may improve the scientist's ability to predict the overt criterion behavior. Affirmation, Intensity, and Formedness as Introspective Opinions. Polling is usually started by asking the respondent to affirm or deny some basal opinion. For example, "Are you for or against X?" usually draws out the pro-con direction of opinion. Later refinements scale the X and ask for the degree or amount of it desired. This affirmation is the basal subclass of opinion about which, according to our theory, eight other mode-tense subclasses of opinion revolve. The central opinion expresses what the respondent thinks or knows in the present tense (and first person singular, active voice, indicative mood). The other eight subopinions (Table 1) qualify it as a logical product qualifies any class-namely by limiting its meaning to what is also the meaning of the qualifying class. Thus the opinion "I think X would make the best president, but I don't expect he'll get it" qualifies the basal affirmation (OTAK in Table 1) with a contrary expectation (+TAK).

(the basal affirmation) ?" This intensity subopinion has been scaled in terms of phrases like "very strongly, strongly, moderately" or in terms of the "give/get ratio."' This latter ratio measures intensity of feeling for an object by what the respondent will give of his time and effort, money, or other sacrifice in exchange for what he affirms in the basal opinion he wants to get.2 Early in polling it was found that respondents with "no opinion" had to be classified separately. Prediction is surer when limited to those who do have an opinion; a large "don't know" percentage in a poll seems a warning of unstable opinion and unreliable prediction. Instead of treating this subopinion as an all-or-none attribute of having or not having an opinion it may be observed in degrees such as: Score Respondent's Behavior (rated by interviewer) 0 No opinion 1 Probing needed to get an opinion expressed 2 A hesitant unready response 3 A normal ready response 4 An abnormally overready response interrupting the unfinished question This score (when better scaled) could measure the "formedness" opinion. It has been called the crystallization or incipiency, or readiness, or preparedness of the basal opinion and of the overt behavior it prepares for. Note that these three subopinions-the affirmation, its intensity, and its formedness-are expressed in the present tense and deal respectively with what the respondent thinks, feels, or is doing about the basal question. They represent the respondent's current introspections as classified in the middle col. in Table 1. They also represent somewhat the historical development of expanding the questioning in polls in order to sample more aspects of opinion. Information, Interests, and Habits as Retrospective Opinions. Next, polls began screening out the uninformed respondents by means of information questions. These may depend on the respondent's classifying himself as to his information about the basal question or they may depend on demonstrated ignorance as in asking "Do you happen to know who is now our Secretary of State?" Information filters are added to polls whenever the 1 Dodd, Stuart C. and Thos. R. Gerbrick, "Word Scales for Degrees of Opinion."

Polls began to probe one's relevant likes and dislikes in the past. They probed the feelings the respondent had built up on anything correlated with the basal opinion. In short, they probed any of his interests from the past that might influence his future behavior. They also probed the respondent's relevant experience. What habits, what skills, what routines has he developed which might influence his future behavior in the respect to be predicted? His past acts obviously would tend to foretell his future acts. The three foregoing subopinions develop the first column of Table 1. For they are retrospective questions finding out what, if anything, the respondent knew or felt or did in the past relative to the basal question. Expectations, Anticipations, and Intentions as Prospective Opinions. A later development in polls, and one still little developed, was to ask the respondent about the future. Here again the knowledge question led off in asking what the respondent expected would happen apart from his own hopes or intentions. "What do you think is most likely to happen?" "What do you think the chances in a hundred are that X will happen?" Such expectation questions tried to get a purely cognitive estimate of perceived probability. Supplementing the respondent's expectations are questions about his anticipations, his hopes and fears, his feelings about the basal questions when projected into the future. These anticipations are partly compounds of the other subopinions. For all the subopinions are apt to be highly correlated together in proportion as the respondent's personality is integrated. His effective anticipations may largely overlap with his cognitive expectations and his conative intentions to act. Also his anticipated feelings in the future will usually show continuity with his present intensity of feeling and his past interests. In fact, all nine subopinions of mode and tense are usually intercorrelated in varying degrees. But they are imperfectly correlated and hence probing each separately may increase their joint predictivity. Finally, a ninth subopinion in polls is the answer to any question as to the respondent's intention to act personally as part of, or as a step toward, the mass behavior to be predicted. Does he express personal responsibility in influencing the criterion behavior of the population by his own behavior? In the absence of biassing pressures a person's expressed intention to act in a specific way may be among the best predicters of such acts. These last three subopinions dealing with expectations, anticipations, and intentions develop the last col. in Table 1. They deal with the future as prospective opinions of the knowing, feeling and doing modes.

This arranges familiar ideas in systematic form and furthers statistical development such as in factor analyses, variance analyses, matrix multiplication, etc. It can help in the inventing of questions for a poll in a new realm by serving as a check list. The poller can ask himself: "Have I invented and phrased questions about each mode separately and about each tense?" "Is such analytic questioning likely to get more predictive answering?"

Each subopinion is jointly characterized as referring either to the past, present, or future tense and as expressed by the respondent in synonyms of feeling, knowing, or doing. The nine-fold opinion is the logical product of two logical sumsthree alternative tenses taken jointly with three alternative modes. It is expected, when predicting a given criterion, that each of the nine subclasses of opinion might be represented by one or more statistical indices and that each index would be reliably scaled in more than all-or-none degrees. To test the mode-tense theory of opinion it may be formally stated as the following set of hypotheses: The summarizing hypothesis is: "How polled people answer questions about their feeling, knowing, or doing in the past, present, or future tends to predict their later relevant behavior." 4 The essence of this hypothesis is that the prediction yielded by any one subopinion in a given situation will be improved by using more subopinions. This summarizing hypothesis is analyzable into nine substantive subhypotheses each of which expects one mode-and-tense subopinion when included in the predictance index to improve the prediction. Then there are five more methodological sub-hypotheses. These subhypotheses expect improved predicting according as the researcher fulfills each of the following conditions: 1) finding the optimally phrased questions and consequent indices to represent each class of subopinion; 2) finding the optimal units for each index; 3) finding the optimal range from origin to terminal points for each index; 4) finding the optimal exponents of the arithmetic indices or multiple regression weightings of the logarithmic indices; and 5) combining the indices for the opinions multiplicatively. Finally, all the above may require some repeating for the three forms of prediction as forecasting in time, estimating from a sample population, and 4The strength of this total tendency may be arbitrarily guessed in the present early stage of research at one half of complete determination by expecting a correlation in general of .71 or higher. This sets a statistically testable goal for the researcher. It is guessed at usually one half of a perfect index of determination (r2) since the modes and tenses are only two of the many dimensions of opinion. The other factors in determining a public's behavior (such as the eight classes of factors in our more inclusive dimensional theory) may well account in general for the other half of the predicted behavior. This correlation, of course, depends on the particular set of indices chosen to represent the nine subopinions, the range of each index, the heterogeneity of the population, and other factors. These indices, ranges and populations will need to be standardized progressively with research such as psychologists have done with intelligence tests.

The predicted mass behavior may be any overt or covert act which many peo- ple do and do often. The predicters are the public's responses in a poll, i.e., the nine subopinions measured before the predicted behavior. The predicting technic is chiefly to test the closeness of fit (and its reliability) of the model to the criterion (Equation 1). This may involve correlating the predicters 5 This theory may be still further formalized in algebraic notation as a mathematical model to further exact testing. In this dimensional form [denoted by square brackets] the mode-tense "predictance" may be written as "a sum of products of powers of basic factors," namely: D t a ~eq. 1, defining [TA~ d f J "JA] "The predict1 1 ance" at time T This defines the mode-tense predictance TA, p set of p persons (1) of the product (it) in each person, of nine (t X a = 3 X 3) mode-tense 1 factors or speech acts (tAa), namely the set of three tense factors (tl) times the set of three mode factors (.a), when each factor is weighted by its exponent (i').

Ideally, the complete procedure should involve going further and specifying the exact curve or model which correlates the predicters with the predicted. If an empirical model is to be developed into a rational model, it should further involve deriving the model mathematically from its assumptions, each of which matches or expresses a social pre-condition. This process of model matching and fitting finds the form and amount of the pre-conditions and their relations to use in predicting in new but similar situations thereafter. In general, the mode-tense theory expects the pre-conditions of the criterion behavior to be more than threshold amounts of each of the nine mode-tense subopinions. The model is specified by Equation 1 (or 3). A theory of human behavior, furthermore, should predict behavior along three chief dimensions. Thus, along the time dimension, the predictive technics should forecast from earlier predicter acts to a later predicted behavior. Along the population dimension, the predictive technics should estimate from the polled sample to the parent population (without any time interval). Along the behavior dimension, the predictive technics should validate the predicter responses in the poll by their multiple regression equation with the predicted mass behavior (when both behaviors are at the same time and by the same persons so that neither forecasting nor estimating are involved). The predictive techniques should predict along these three dimensions of time, people, and their acts, both when each varies alone with the other two held constant, and when they vary in any combination. A scientific theory should also be a system of hypotheses or principles, each of which is testable and has a specified technic for testing it. In the dimensional theory proposed here each hypothesis can be tested in suitably designed polls. The substantive hypotheses relate predicters to the predicted behavior or to each other. These relations define the system which may be expressed as a mathematical model or equation of the variables and their ex- pected relationships. A dimensional model is proposed here defined as a sum of products of powers of nine basic factors. The methodological sub-hypotheses here expect that each specified technique will improve the prediction (Equation 2 or 4). A final specification for a scientific theory is that the variables and their relations be operationally defined as far as necessary to reproduce them reliably. In the "mode-tense" theory, every variable can have the identifying type of operational definition provided by the best currently known techniques or demoscopes or scientific polls. Demoscopes can also help to provide the fuller operational definitions of the generating and of the adapting types. These three types deal with the operations of the present, past, and future, respectively. Among them they state the contents, causes, and consequences This content downloaded from 158.143.233.108 on Wed, 03 Jun 2020 19:24:20 UTC All use subject to https://about.jstor.org/terms A PREDICTIVE THEORY OF OPINION 579 of the term defined in telling how to know it (identifying type), how to make it (generating type), and how to use it (adapting type). Identifying a defined object in the future tense is predicting it; generating the object in the future is controlling it; adapting the object in the future for use in the further future is controlling it still more ultimately. Since prediction and control are the major functions of science, operational definitions thus become the major means of carrying out the functions of science. In testing this mode-tense theory by its predictive ability, an important and prevalent case should be noted. This case is when the predicter and the predicted coalesce. They become the same variable wherever the time interval between the predicter poll and the predicted behavior becomes zero. Whenever the criterion mass behavior is the same as the poll behavior and we want to know simply the public's polled opinions, then the problems of forecasting and of validity both vanish. Predicting shrinks to a matter of estimating the results in the parent population from the sample with a known degree of reliability. Testing this general theory of modes and tenses of opinion will require inventing specific scaled indices defined by the questions asked about each of the nine subopinions.7 This involves searching for indices with lowest intercorrelations in order to maximize their multiple correlation predicting the criterion. Testing will require using the best techniques of predicting' and of polling.9 All the hypotheses may be tested simultaneously or in subsets as opportunity offers. Corroborating tests under diverse conditions will be required to progressively map the limits and the possibilities of this theory. THE CONSISTENCY WITHIN AND BETWEEN THEORIES-SOME INDICATIONS Any scientific theory is first tested by its correspondence to the facts, including its ability to predict them, and second by its consistency within itself and with existing theories. Let us turn to this second broad test of truth. How consistent is this mode-tense theory within itself and with other theories of public opinion? In considering internal consistency, the relations between the variables are 7 Dodd and Gerbrick, op. cit. 8 See John Dollard, "Under What Conditions Do Opinions Predict Behavior," Public Opinion Quarterly, Vol. XII, (Winter 1948-1949) No. 4; Dodd, "A Measured Wave at Interracial Tension," Social Forces, Vol. 29, (March 1951) No. 3; Paul Horst, "The Prediction at Personal Adjustment," Social Science Research Council Bulletin, 48, 1941. 9 See Hadley Cantril, Gauging Public Opinion.

Positive correlations are to be expected on psycho- logical grounds among the three modes of opining in proportion as the personalities are integrated. Positive correlation is to be expected furthermore, among the three tenses in proportion as the polled personalities are con- tinuous or stable in time. But these intercorrelations will not, in general, be perfect, and may often be low. Measuring each of the nine mode-tense subopinions, therefore, is likely to increase the multiple correlation of these predicters with the later predicted behavior. This is the main justification for proposing the mode-tense theory. The essence of this theory is that each mode and tense subopinion will, in general, contribute something to predicting the criterion over and above the other subopinions. This implies intercorrelations that are not too high relative to their criterial correlations. The degree of consistency of this theory with other theories of opinion is hard to determine. Since most other theories or definitions and discussions of public opinion are in non-operational terms, their exact meaning is often elusive. They often seem to be translatable into the operationally defined 10 At present we expect the multiplicative combination as in Eq. 1 to predict better, providing the indices are optimal as specified above. We expect this because the nine subopinions seem to us to be jointly and simultaneously present and conditioning each person's behavior and not present as alternatives that can substitute for each other. Joint presence is symbolized by the logical product in unquantified data and by algebraic products in quantified data, while alternative presence is symbolized by the logical sum in qualified data and by the algebraic sum in quantified data. Another reason we see for expecting the subopinions to be factors and not addends is that if any one of them were to be zero in amount (if it could be perfectly measured on an absolute scale), the resulting total opinion would be non-existent. A product vanishes thus when any factor is zero while a sum does not vanish when one addend becomes zero. The product thus expresses a more intimate or intrinsic or mutual union than a sum. Thus chemists symbolize chemical union in a molecule as the product of atoms and symbolize a physical mixture as a sum. In a product the factors interact and influence each other, while in a sum they are merely piled inertly together, as it were. On the other hand, our current indices of these opinion factors are probably still so crude that additive or linear combining of them may be adequate. This linear treatment has the weight of decades of conventional statistics behind it. The mode-tense theory is here stated so that this issue can be experimentally decided. The multiplicative combination with factors weighted by their exponents or logarithms has been found in two cases where it has been explored. Thus Zimmerman found it between a decision time index of formedness and intensity. Dodd and Griffiths found it between affirmation and intensity when whites expressed their social distances from Negroes, Chinese, and Japanese. But these are only hints of what the relation may be in general. See: L. Postman and C. Zimmerman, "Intensity of Attitude as a Determinant of Decision Time," American journal of Psychology, Vol. 58, 1945, pp. 510-518; S. C. Dodd and K. Griffiths, "The Logarithmic Relation of Social Distance and Intensity," journal of Per- sonality, 1957.

No exhaustive comparisons will be undertaken here, but a few examples will be noted of the relations of the mode-tense theory to Gallup's quintamensional design, to Guttman's Cornell scales, to Dodd's theory of tensions, to Parson's theory of social action, and to some general classifications in the literature. In Gallup's quintamensional design, his open-end and closed-end questions deal with the basal opinion in the mode-tense theory. His intensity and information questions are those subopinions in the mode-tense theory. His "reasons why" question covers our "interests" and "habits" for retrospective reasons and our "anticipations" and "intentions" for prospective reasons. The mode-tense theory then agrees with the quintamensional design but analyzes the respondent's total opinion more fully into nine sub-classes instead of five. In Guttman's scale analysis his "first component" is our basal opinion.11 His second component is "intensity" in both theories. His third component "closure" seems largely identifiable with our "formedness." His dimly discerned fourth component which seems something like "ego-involvement" may prove equatable to our "retrospective" opinions (Column 1 in T'able 1). A major weakness in Guttman's scaling theory has been his definition of an attitude universe as all possible statements of that attitude and then providing no sampling technique permitting one to say that "the arbitrarily selected but 90 per cent reproducible set of statements show that the universe is scalable." The nine modetense classes begin to stratify that universe. They do not specify the frequency of statements in each stratum, but they can help qualitatively in assuring that these major strata at least are represented in the poll. In Dodd's tension theory a tension ratio or valuation is defined as the ratio in a person or in a plurel of intensity of desire divided by the amount of what is wanted.12 Broadly it is the ratio of demand to supply for economic desiderata or of "unit cost," "unit price," "unit worth," for any objects of value to the responder. It is measured as his "give/get" ratio, dividing an index of what he will give or do (for what he wants) by an index of what he wants to get (or keep). Tensions are hypothesized to cause behavior in the sense that any striving behavior, (a) occurs later in time, and (b) correlates with the earlier observed tension ratio, and (c) changes predictably after the tension changes (under specified conditions, of course). By suitable notation for statistical treatment, tension ratios, and tension products are organized in matrices to manipulate their varying distributions among per11 See Uriel G.

This tension theory can become a special case of the mode-tense theory whenever the basic affirmation in Table 1 states what is wanted (the desideratum) and the intensity and formedness cells of Table 1 state what is concurrently felt about it or done to get it. In Parson's theory of social action the part dealing with "motivational orientations" of people deals with opinions especially.'3 Motivations are analyzed into the three "modes": 1) "cathectic" involving affect or feelings; 2) "cognitive" involving perception, etc.; and 3) "evaluative" involving energy expenditure. This over-simplified resume suggests high correlation between this part of Parson's theory and the three modes of speech behavior. Many trichotomies of the past, however, have had one great difficulty (among many lesser ones); they were difficult to observe reliably, because they lacked operational definitions. The scientist was unable to say of a given act or index exactly how much of affection, cognition, or conation it represented. The mode-tense theory cuts this Gordian knot of semantics by operationally defining the three modes by the highly observable speech behavior that can be recorded verbatim on every poll questionnaire. Of course semantic problems still exist but they can now be measured and manipulated and their effect on predicting can be experimentally determined. Thus some people sometimes say "I think-" to express affect, or "I feel-" to express cognition. These individual deviations attenuate but do not obliterate the larger fact that saying "I feel-" usually expresses feelings predominantly; saying "I think-" usually expresses cognition predominantly, etc. These speech modes in the mode-tense theory are expected to predict a large public's criterion behavior better than every individual's behavior. Furthermore, by basing the theory on observed speech behavior most semantic and other arguments about faculty psychology, whether the modes are ele- mentary, compound, or intervening variables, etc., become irrelevant. For whatever the intercorrelation of the three modes may be and whatever their criterial correlations may be, the theory simply claims that the three modes and tenses, jointly in a team, will yield a larger multiple correlation with the criterion to be predicted than they yield separately. This team treatment also permits the use of words that blend modes, such as "satisfy," since the blending can be analyzed by correlational and factor analyses. The consistency of the three modes of behavior with other three-fold 13 See Talcott Parsons and Edward A. Shils, Toward a General Theory of Action.

The sizes of the possible correlations between any two rows in Table 2 are unknown, but might be charted with suitable research.

The three modes seem largely centered in the activity of the three neural regions respectively. Then since the basis of the tense classification is time, the mode-tense theory would be subclassifying opinions by the two most basic dimensions of every empirical science, space and time.'4 TWO EXAMPLES OF THE USE OF THE THEORY Election Prediction. A major problem in polls predicting elections as in any predicting poll, is finding the most predictive set of questions to ask. The mode-tense theory may help here in suggesting "Ask one or more questions of each of these nine kinds. Invent and scale the most relevant questions 14 In studying the three tenses of human activity, note the physicists parallel in subclassifying "energy" into "work," "kinetic energy," and "potential energy." These concepts have the same dimensional formula but mean energy in the past tense, in the present tense, and in the future tense, respectively.

It reminds him to ask all about the respondent's goals, his stimulation, and other situational factors. It suggests asking about the timing-How long? When? How fast? How frequently? How recently? How soon? etc. It prompts spatial questions -How near or far? Where? How dense? How ubiquituous? etc. Among these seventeen classes of predicter variables, it may be expected that in general the nine mode-tense classes will usually be the best predicters. For they are the criterion behavior observed in its preparatory stages. Rumor Control. An example of the mode and tense analysis of opinion going beyond prediction to, develop a bit of control of human behavior is in the field of rumors. In psychological warfare (as in advertising, etc.) one wants to spread rumors favorable to his own side while preventing the spread of the enemy's rumors. To vary or to control such diffusing of messages from person to person requires knowing and manipulating the conditions conducive to rumors. These conditions can be described in terms of the mode-tense theory as follows. Rumors thrive when the people lack information-whether because of censorship, or because of a disaster disrupting information channels, or because emergency news is happening faster than it can be authoritatively collected and published. Rumors thrive when the people intensely desire that lacking information. It is of unusual import to them-it may mean victory or defeat in the war, or emergency threats to their homes and loved ones, etc. Feelings are intensified whether in hope or in fear. These two conditions which are so conducive to rumors mean a rising "feel/know" ratio, AF/AK in Table 1. A successful rumor tends to reduce this feel/know ratio back towards the normal. It makes people think they know something they wanted to know; it builds up their hopes or reduces their fears by airing and sharing them. This means that to spread a rumor, when desired, the feel/know ratio must be increased as a pre-condition. To check a rumor its relevant feel/know ratios must first be decreased. 15See Stuart C. Dodd, "Human Dimensions-A Re-search for Concepts to Integrate Think- ing," Main Currents in Modern Thought; "On Classifying Human Values," American Sociological Revieiw, Vol. 16, (October 1951) No. 5; "Sociomatrices and Levels of Interaction," Sociametry, Vol. XIV, (May and August 1951) Nos. 2 and 3; and "The Intteractance Hypothesis," American Sociological Review, Vol. XV, (April 1950) No. 2.

This means lower ex- pectances, +TAK in Table 1. Thus the mode-tense formula for controlling rumors is chiefly: (a) restore dependable expectations; (b) decrease abnormal feelings; (c) increase information. This means reducing the quantity: (In Table 1) AF/T AK +TAK. Allport and Postman state that the two major factors in rumor spreading are ambiguity and importance.'6 The ambiguity of the situation is represented by lack of information and unsettled expectations in the mode tense formulation, while the importance factor is largely represented by strong feelings. The mode-tense theory of opinion is thus a possible aid in predicting and controlling rumor behavior. 16 See L. Postman and Gordon W. Allport, The Psychology of Rumor.
