Final answer:
The exact percentage of psychology majors entering the workforce immediately after obtaining their bachelor's degree without attending graduate school is not specified in the given data. Instead, references indicate only 27% of college graduates work in their studied field, and general educational trends show a lower percentage of people holding bachelor's degrees compared to high school diplomas.
Step-by-step explanation:
The specific percentage of psychology majors entering the workforce immediately after completing their bachelor's degree, without pursuing graduate education, is not provided in the given references. However, it's noteworthy that according to a Washington Post article by Brad Plumer in 2013, only 27 percent of college graduates have a job related to their major, which may suggest that a significant portion of psychology majors might enter the workforce in fields not directly associated with their degree.
Moreover, educational statistics from the Bureau of Labor Statistics (BLS) indicate that as of 2019, significantly more Americans are completing high school than are earning bachelor's degrees, with 90% having a high school diploma but only 36% holding a bachelor's or higher degree. This helps us understand broader educational trends but does not directly answer the question regarding psychology majors' employment post-bachelor's degree.
