What is Cross-Temporal Meta-Analysis

The purpose of this chapter is to summarize changes in personality traits that have co-occurred with the rise of new social media, and to evaluate the plausibility of the hypothesis that new social media are a partial explanation for these dramatic changes. Studies have found a rise in social disconnection among recent generations of young Americans. Self-esteem and narcissism have been rising in college students from the late 1970s to 2010, with simultaneous declines in empathy. Scholars and lay people alike blame the rise of the internet, and in particular, self-oriented and self-promoting “social” networking sites. This new media landscape could lead to increasing social disconnection even as it superficially increases our social connections, and several studies suggest a direct link between social media use and social disconnection. However, since most research thus far is correlational, interpretations are limited, leaving open more optimistic possibilities for new social media.
