Are today’s young people more narcissistic than previous generations? And how else are they different – or the same?
Last week’s story in the New York Times science section focused largely on the disagreement around these questions. Of course, it’s challenging for a newspaper article to cover all of the issues, especially when covering science, and thus difficult for readers to have all of the information they need to judge for themselves.
So that’s what I thought I’d do here. Interested readers, bloggers, etc. can look at the data and make their own judgments. Reasonable people can disagree, but it is best to do so in the context of all the findings. Even if you can’t read all of the articles, just getting a feel for the scope of the research should provide a better view of what we know about generational changes.
The research findings fall into 5 main areas: 1) narcissism, 2) positive self-views and other traits related to narcissism, 3) cultural products such as language use, 4) positive trends connected to individualism, and 5) the validity of the Narcissistic Personality Inventory (NPI).
1. Increases in narcissism: Four cross-sectional, one retrospective, and four over-time datasets are consistent with higher narcissism among those in more recent (younger) generations. These use three different measures of narcissism (the NPI, the California Psychological Inventory, and a clinical interview for Narcissistic Personality disorder) and occur across several age groups and cultures:

2. Traits related to narcissism have also increased, such as extrinsic values, unrealistic expectations, materialism, low empathy, agentic (but not communal) self-views, self-esteem, self-focus, choosing more unique names for children, less concern for others, less interest in helping the environment, and low empathy. Studies consistently show increases in these traits, except the data on self-esteem are mixed. Self-esteem increases in elementary school, middle school, and college students, but is unchanged among high school students in 2 out of 3 studies. Many of the studies below use data from Monitoring the Future, the same database of high school students that critics claimed showed no meaningful generational differences.

3. A wide range of cultural data also suggests growing individualism and waning collectivism, including changes in pronoun use in books and song lyrics, agentic words and phrases, decreasing moral words, and more emphasis on fame in TV shows for children.

4. Individualism is also linked to attitudes supporting equality for all regardless of group membership. Plenty of evidence – both from academic journals and from polls -- suggests that younger generations are more tolerant and supportive of equality. Note that supporting equality and empathy are not the same thing.

5. Finally, the NYT article critiqued the Narcissistic Personality Inventory, suggesting it did not measure narcissism but instead measured “desirable traits.” Although some NPI items might seem fine in isolation (e.g., “I am assertive”), the total score predicts narcissistic behaviors, not just a few items. In addition, other items don’t sound quite as desirable (“I can live my life any way I want to,” “I find it easy to manipulate people.”)
The NPI is the most well validated measure of trait narcissism. It is not designed as a clinical measure (contrary to the NYT’s statement that “the NPI is a tool commonly used by psychologists to identify both clinical and borderline narcissism”), but correlates strongly with clinical assessments. Some research suggests narcissism has grandiose and vulnerable forms. The NPI captures grandiose forms. A large body of research has covered these issues. For example:

I welcome further thoughts on this topic, including generational differences you’ve observed, possible causes, other papers finding generational differences or similarities, and research to do next.
