GOING TO UNIVERSITY is supposed to be a mind-broadening experience. That statement is probably made in comparison to training for work straight after school, which might not be so encouraging. But is it actually true? Jessika Golle of the University of Tübingen, in Germany, thought she would try to find out. Her result, however, is not quite what might be expected. As she reports in Psychological Science this week, she found that those who have been to university do indeed seem to leave with broader and more inquiring minds than those who have spent their immediate post-school years in vocational (职业的) training for work. However, it was not the case that university broadened minds. Rather, work seemed to narrow them.
Dr. Golle came to this conclusion after she and a team of colleagues studied the early careers of 2,095 German youngsters. The team used two standardized tests to assess their volunteers. One was of personality traits, including openness, conscientiousness（认真）and so on. The other was of attitudes, such as realistic, investigative and enterprising. They administered both tests twice—once towards the end of each volunteer's time at school, and then again six years later. Of the original group, 382 were on the intermediate track, from which there was a choice between the academic and vocational routes, and it was on these that the researchers focused. University beckoned for 212 of them. The remaining 170 chose vocational training and a job.
When it came to the second round of tests, Dr. Golle found that the personalities of those who had gone to university had not changed significantly. Those who had undergone vocational training and then got jobs were not that much changed in personality, either—except in one crucial respect. They had become more conscientious.
That sounds like a good thing, certainly compared with the common public image of undergraduates as a bunch of lazybones. But changes in attitude that the researchers recorded were rather worrying. In the university group, again, none were detectable. But those who had chosen the vocational route showed marked drops in interest in tasks that are investigative and enterprising in nature. And that might restrict their choice of careers.
Some investigative and enterprising jobs, such as scientific research, are, indeed beyond the degreeless. But many, particularly in Germany, with its tradition of vocational training, are not. The researchers mention, for example, computer programmers and finance-sector workers as careers requiring these traits. If Dr. Golle is correct, and changes in attitude brought about by the very training Germany prides itself on are narrowing people's choices, that is indeed a matter worthy of serious consideration.
