Attitude and Attitude Change: The Social Judgment-Involvement Approach

The book argues that an attitude is not a single point on an evaluative scale but a structured range: a latitude of acceptance, a latitude of rejection, and a latitude of noncommitment, all organized around a personal anchor. Persuasion is judged against this structure. The more ego-involved the person, the narrower the acceptance latitude and the wider the rejection latitude. This rejects the assumption that attitude change is a simple function of message strength, source credibility, or repetition. The Sherifs hold that the same message can be assimilated, contrasted, or produce genuine change depending on where it falls relative to the receiver's existing latitudes and anchor, which are themselves anchored in reference groups.

The book consolidates the social judgment-involvement approach, including latitudes of acceptance, rejection, and noncommitment, assimilation and contrast effects, anchors, and ego-involvement. These concepts extend the Sherifs' earlier collaboration with Carl Hovland in Social Judgment (1961) and their work on ego-involvements with Hadley Cantril. The framework has been applied in persuasion research, political communication, advertising, and risk communication, where the practical question is often why messages aimed at highly committed audiences backfire. It is also a standard reference point in the two-step tradition of attitude research, sitting between the Yale message-learning approach and later cognitive-response and elaboration-likelihood models, though it remains less mechanistically specified than those successors.

Hovland's Yale program, developed at Yale in the 1940s and 1950s, treated persuasion as a function of source, message, channel, and receiver variables that could be manipulated to increase or decrease effectiveness. The Sherifs shifted the explanatory weight to the receiver's pre-existing structure of attitudes. Where Hovland asked what makes a message persuasive, the Sherifs asked why identical messages produce acceptance in some receivers and boomerang effects in others. The 1961 volume Social Judgment, co-authored with Hovland, marked a partial convergence, but Attitude and Attitude Change (1965) is the more distinctly Sherifian statement, foregrounding ego-involvement and reference groups rather than message variables. The two traditions are best read as complementary rather than competing.

A frequent misreading treats high ego-involvement as simple resistance to all persuasion. The framework actually predicts a pattern: messages within the latitude of acceptance are assimilated and may produce movement toward the message, though typically less than for low-involvement receivers, while messages in the latitude of rejection are contrasted and can shift the person away from the advocated position. The practical implication is counterintuitive—persuaders targeting highly involved audiences should position messages near the edge of the acceptance latitude rather than at their own preferred position. This is often lost when the framework is reduced to a slogan about involvement breeding resistance, which misses the assimilation side of the theory.

The book is a mid-career synthesis of the Sherifs' long-running project: attitudes are properties of persons-in-groups, anchored in the standards of reference groups rather than in isolated individual dispositions. It follows their textbook Social Psychology (1956) and Social Judgment (1961), and it is closely related to the edited volume Attitude, Ego-Involvement, and Change (1967), which collected conference papers applying the same framework. Across these works the same move recurs: the meaning, stability, and changeability of an attitude depend on the groups that provide its frame of reference. Attitude and Attitude Change is therefore best understood as a statement of a framework developed over decades rather than as a standalone contribution.

The framework's core insight—that receivers evaluate messages relative to their own positions, and that involved receivers may contrast rather than accept—has survived in persuasion research, though later models specify the underlying processes more precisely. Cognitive response theory and the elaboration likelihood model replaced or supplemented latitudes and anchors with constructs such as thought listing, argument quality, and processing motivation. The Sherifs' emphasis on ego-involvement and reference groups has been partly absorbed into research on social identity and on resistance to persuasion. The book is now cited more as a historical statement of the involvement tradition than as a current operational model, and its specific predictions about latitude widths have been only partially tested in subsequent work.
