In everyday language, the notion of a generation is commonly used as an explanation of differences in experiences and outlooks between older and younger people in society. The idea of a âgeneration gapâ, for example, assumes clear distinctions between age groups who have grown to adulthood at different periods of historical time. In a similar way, generation is often used as a measure or marker of social change, so that a person might say âOh that would never have been the case a few generations agoâ, or âMy grandchildrenâs generation will expect something different from lifeâ. Both of these everyday, popular uses of generation rest upon an assumption that the experiences and outlooks of age groups are likely to be dissimilar and, further, that such dissimilarities are understandable by reference to the different âlocationsâ of age groups in time. In sociology, similar links are made between a personâs location in an historical social structure and their views or conceptions of the social world, via the concept of cohort. Sociologically, cohort contextualises the lives of individuals; first, within the specific interval of historical time into which they are born, grow up and old; and, second, within the company of their coevals (other individuals of the same, or similar, calendar age). As a consequence of their cohortâs location in historical time, individuals and their coevals share an exposure to certain experiences and opportunities and are excluded from others.
As noted earlier, survey evidence shows the importance of age in predicting attitudes and behaviour, but such data âonly describe our problemâ (Abrams 1972: 109). Theories seeking to explain why younger age groups demonstrate a tendency to hold more progressive attitudes than older age groups can be traced back to the ancient Greek philosophers (Nash 1978). More recent examples include the writings of Ortega y Gasset (Spitzer 1973) and the work of the French Annates school (Esler 1984). However it is Karl Mannheimâs (1952) essay âThe Problem of Generationsâ which is widely regarded as the most systematic and fully developed treatment of the cohort aspect of the ageing process from a sociological perspective (Bengtson, Furlong and Laufer 1974). Accordingly, it is Mannheimâs theory which centrally influenced the conduct of the study reported in this book. In his essay, Mannheim uses âgenerationâ in the sense of âcohortâ. In the following discussion, I place âsocialâ before all instances of Mannheimâs use of âgenerationâ. In this manner, account is taken of the need to be careful in use of terminology, whilst links are maintained with sociological, and cultural, traditions which refer to âgenerationâ, meaning cohort. A second reason for introducing the concept of social generation is that Mannheimâs theory represents an elaboration of the concept of cohort. Recognition that individuals belong to a cohort sensitises us to the fact that their location in historical time exposes them to certain experiences, crises and events and excludes them from others. Mannheim takes this idea further. He suggests that there is a key period of exposure, namely, during youth, which has lasting ideological effects. In other words, Mannheimâs argument is that, as a result of differential exposure and exclusion due to location in historical time, there exist different social generations, each having distinctive world views. This, in turn, leads people of different ages to experience the same social and cultural events differently.
Mannheimâs theory of âgenerationsâ
Mannheimâs (1952) essay on cohort processes is regarded as seminal because it firmly locates cohort within socio-historical contexts, and moreover, is part of a wider sociological theory of knowledge. For Mannheim, âknowledgeâ (defined by him as a style of thought or world view) is seen as socially conditioned by its location in a socio-historical structure. While discussions in the sociology of knowledge have focused on class location (Abercrombie 1980), Mannheim also identifies cohort location as a key element in the social determination of knowledge. Cohort location, like class location, points to âcertain definite modes of behaviour, feeling and thoughtâ (Mannheim 1952: 291). In the case of class location, an individual or groupâs position emerges from the existence of an economic and power structure within society. The structure from which cohort location emerges is the âexistence of biological rhythm in human existence - the factors of life and death, a limited span of life, and ageingâ (Mannheim 1952: 290). Although recognising the influence of biological factors, Mannheim stresses the overriding and ultimate importance of social factors, so that biology is seen to be embedded within social and historical processes. Mannheim is not, of course, implying that mere chronological contemporaneity produces a common consciousness: indeed his contention is that âall people living at the same time do not necessarily share the same historyâ (Troll 1970: 201). Consequently, contemporaries may experience the same social and cultural phenomena or historical events differently.
For Mannheim, chronologically contemporaneous individuals (that is, all persons now alive) are stratified by the tendency for the formative experiences and early impressions of youth to âcoalesce into a natural view of the worldâ (Mannheim 1952: 298). The individual carries this with them throughout the life span. People are thus crucially influenced by the socio-historical context that predominated in their youth, and in this way, social generations have distinctive historically determined world views. Mannheim is proposing that in order to share social generational location in a sociologically meaningful sense, individuals must be born within the same historical and cultural context and be exposed to particular experiences and events that occur during their formative adult years. This is the general level of social generational location identified by Mannheim. He also provides a more specific and sophisticated analysis of social generational location. First, he recognises that geographical and cultural location will act to internally differentiate social generations, so that not every member will be exposed to exactly the same experiences. Second, he distinguishes between those social generational groupings who actually participate in the key social and cultural events of their time and place and those who do not. Thirdly, he recognises that within âactualâ social generations, there may arise differing and opposing responses to social and cultural events, in that there may develop opposing social generational âunitsâ.
Mannheimâs discussion of social generations is integrally concerned with the issue of social change (Laufer and Bengtson 1974). Thus he maintains that the likelihood of a cohort developing a distinctive consciousness (of becoming a social generation) is dependent on the tempo of social change. In turn, social generations are regarded as a key element in the production of social change. The âfresh contactâ of new cohorts with the already existing cultural and social heritage always means a âchanged relationship of distanceâ and a ânovel approach in assimilating, using and developing the proffered materialâ (1952: 293). The progression of social change is made smoother by the presence of âintermediaryâ (or buffer) social generations. The implication here is that social generations with the least difference in world views or styles of thought are always adjacent to one another, whilst those with the greatest difference are non-adjacent. In times of accelerated social change, however, when normality is disrupted, the ânew broomsâ have even greater opportunity and access than the natural, gradual change over, brought about by the ageing and eventual death of all members of a cohort, allows.
The strength of cohort and social generational perspectives, such as Mannheimâs, is their grasping of the defining concern of sociology as a discipline, that is, the relationship between history and biography within society (Mills 1970). Yet a range of conceptual and methodological difficulties arise when conducting empirical research on cohort and social generational processes.
The empirical study of the formation, development and retention of world views over the life course is made problematical by the complex entangling of two further âtimeâ elements, in addition to cohort or social generational experiences : those of ageing or individual biography and of historical or period events. Consequently, researchers may emphasize any one, or a combination, of these three central influences. Stage in life course effects, as in ârebellious youthâ or âconservative old ageâ, may be invoked. Period effects (historical, political or economic events or crises) may be seen to influence the world views of people of all ages and cohorts. Finally, explanations may centre around cohort effects, which arise from the importance of adolescent and early adulthood experiences within particular historical contexts for the formation of world views, which then persist over the life span. Empirically, it is difficult, if not impossible, to separate these three central influences (Alwin et al 1991).
The authors of one major recent study (Alwin et al 1991) favour the âgenerational-persistence modelâ as a âusefulâ summary of what is known about the formation and development of socio-political orientations over the life course. The âgenerational-persistence modelâ (or more properly, the cohort-persistence model) has three components. First, the notion of a period of vulnerability to influence, occurring in late adolescence and early adulthood. Second, the notion that each new cohort experiences that time of life differently, and that there are unique residues within the individual because of those experiences. Third, the notion that, after some early period of influence and change, attitudes become crystallised and increasingly stable with age (Alwin et al 1991: 264). Research evidence is particularly supportive of the first and third components of the model. The importance of late adolescence as a key period of socialization is widely accepted (for review, see Braungart 1984). Moreover, research has found that people of all ages tend to report historical events and changes that occurred in their youth as especially important or meaningful (Schuman and Scott 1989; Stewart and Healy 1989). Evidence also strongly supports the notion that, once formed, world views are retained over the life span (Braungart 1984). Whilst considerable evidence exists in support of the first and third components of the model, opinion as to the long term effects of social generational or cohort experiences (the second component) is rather mixed. In reviews of available evidence, some conclude that there is a degree of support for long term social generational effects (for example, Roberts and Lang 1985), albeit âmeagreâ (Alwin et al 1991). Others argue that little systematic evidence exists for the lasting effects of social generational experiences (for example, Schuman and Reiger 1992). Still others find that social generational differences may vary as a function of particular issues (for example, Glass et al 1986; Kalish and Johnson 1972; Sears 1983). Alwin et al (1991) reach the conclusion that evidence (including their own) supports the âgenerational-persistence modelâ. However, they argue that the model may give too much emphasis to cohort processes and neglect other variables. They also suggest that the model may give too much emphasis to the stability of orientations over an individualâs life course, in the face of evidence which shows that changes do occur over time.
