Contrary to popular belief, recent claims that narcissism in recent generations is on the rise, are false. While researchers like Jean Twenge and Joshua D. Foster have released papers that find their own findings, that the modern generations are more self-centered and narcissistic, there are also researchers like Kali Trzesniewski and M. Brent Donnellan, who have negated every study by Twenge and her college’s. The studies that “prove” that narcissism is more prominent in recent decades then past ones have so many flaws that any conclusion that could be drawn from them, are false.
In 2008, Twenge, Konrath, Foster, Campbell, and Bushman, published a study that concluded that narcissism in recent generations is on the rise. By examining Narcissistic Personality Inventory (NPI) scores of 85 studies, made up of college students (all within the same age range at the time of taking the test) between 1979 and 2006, Twenge et al., (2008) found that, “ since 1982, NPI scores have increased 0.33 standard deviation” (p. 875). …show more content…
The first obvious error cited by Trzesniewsky et al., (2008a), is that the sample group isn’t made up of probability subject assignments, but rather convenience samplings. As concluded by Pedhazur and Schmelkin (1991), “convenience sampling makes it impossible to estimate sampling errors accurately, so there is no way to evaluate the validity of population inferences (as cited in Trzesniewsky, 2008a, p.
