Sociologists throughout the history of the discipline have been interested in the transition from traditional forms of social organization to modern society, which is characterized by capitalism, free markets, individualism, bureaucratic social organization, and a weakening of community and family ties.
The transition to modernity created a mass-society, or a society in which the growth of bureaucracy and the quest for material wealth has weakened traditional forms of solidarity and changed the nature of social relationships. Mass-society is characterized by bureaucracy, which is a very impersonal way of dealing with each other.
Max Weber theorized bureaucracy and said that people were going to be living in an iron cage, meaning an impersonal, cold, calculated bureaucratic iron cage, in which people are not engaging each other emotionally and intensely, but rather going through the bureaucracy to engage each other. Living in this bureaucratic shell can be quite stifling, and to some extent, might characterize society today.
Your personality is influenced by the society you inhabit and by the social relationships that you have. Each period, or form of social organization, whether it is traditional or modern mass society, has its own associated social character. A social character is a typical pattern of personality and behavior common to members of a society, at a historical point in time.
The social character today is different than it was hundreds or even 50 years ago. Looking at just one category--gender, for example--you can see huge changes in patterns of behavior and personality over the last century. The social character today is certainly different than it was in the traditional era, before the Industrial Revolution and the beginnings of capitalism. Capitalism radically changed people in society, as well as radically changed their social character--they had to be transformed into a laboring society.
One way to conceptualize changes in social character with the transition from traditional society to modernity society is inner-directedness versus other-directedness.
Inner-directedness is a social character that ordains in premodern, traditional societies. Inner-directedness is inherently conservative and resistant to change. People are focused steadfastly on the maintenance of tradition and time-honored ways of doing things, and are therefore repeating the traditional patterns of behavior--they are inner-directed. There is little change in society--you know your place when you're born, and you have little pretense for social mobility. In fact, in inner-directed societies, there are very few institutional channels to even promote social mobility.
Other-directedness, on the other hand, is the social character that ordains in modern societies. People are no longer bound to tradition and time-honored ways of doing things. Society now, relative to traditional pre-modern societies, is incredibly flexible--you can experiment with different personalities, identities, careers, and potential selves.
Societies are continuously in motion and socialization occurs in this context. People become much more other-directed, or directed at winning the approval of others and making good self-presentations and impressions in the eyes of ever-shifting groups of others, as they move about society. Other-directedness is a social character that is outwardly focused on being popular, well-liked, and fashionable.
Postmodernity is the stage of social development in which society has moved beyond modernity and industrial production to a post-industrial society. If modernity--capitalism and modern society--was ushered in by the Industrial Revolution, then, scholars argue, we are currently in a postmodern period, a post-industrial society, ushered in by computer technology and the information revolution. The economy is no longer grounded in heavy industry, but rather, it is grounded in information processing.
People want to be seen and treated in a socially differentiated fashion in postmodernity. Before, in the modern period, there was all kinds of mass production, with everyone consuming mass-produced items. Now, this isn't the case. People have unique identities, cultures and cultural politics.
IN CONTEXT
All of your basic needs have been met--you’re not starved materially, so now that those needs have been satisfied, you can focus on other, lighter things, like culture and cultural movements and equality. This is a luxury in wealthy, advanced capitalist societies--it's myopic to talk about post-modernity with respect to African societies; it doesn't make sense. However, it might make sense in the context of an advanced capitalist post-industrial society.
