Research shows that no clear agreement exists on whether generational differences exist. Jones (2018) acknowledged the widespread belief in generational differences but called for further research to test the predicted stereotypes of different generational cohorts. Perry (2015) suggested that some limitations in current research on generational differences could be addressed by future research but also questioned the assumption that generational stereotypes exist. Overall, the papers indicate that generational differences are a topic of debate and require further investigation.

- There are no significant differences in academic achievement between first and second-generation immigrant youths.
- Millennial workers generally have higher expectations than their non-Millennial colleagues, but the importance ranking of the various dimensions is largely similar across generations. These findings held even after controlling for age, work experience, and job tenure effects.
- There is no strong connection between which generation you belong to and how well you do at work. Sometimes, there's no connection at all.
- Younger people often get treated unfairly because of their age, making them feel bad. This study examined how people think about other people of different ages in the workplace. They found that feeling good or bad can affect how they act towards that person.

Therefore, it may be wise to approach this topic cautiously and not rely too heavily on assumptions about generational differences when making decisions in your organization.
