Evidence suggests that the interests measured by these tests are stable. For example, we tested a 39-year-old woman college professor named Jean A. on the SCII. The test was given twice, separated by 11 years. At the first testing, Jean was a 28-year-old psychology graduate student who had not started her professional career. Table 14-3 compares her SCII profiles at ages 28 and 39 During this 11-year interval, Jean completed her Ph.D., held three different jobs, and had two children. As the table shows, her interests remained remark- ably stable.
