The first issue raised involved their technique of cross-temporal meta-analysis, which compiles data from a questionnaire for an extensive number of years. With this concern Trzesniewski and colleagues (2008) questioned Twenge’s study’s use of college students at 4-year institutions due to the fact that such a section only represents about 20% of the population of Americans at age 18-24. This raised the concern applicable to all convenience sampling, Trzesniewski claims, that estimating sampling errors are extremely difficult to determine in convenience sampling, highlighting that the trends seen in the result may be due to the change in people who attended college or even those who participated in psychology research in 1970s or 1980s to the 1990s and 2000s.
