The Economics of Higher Education, Part 1: Science Is Hard

If you are the sort of person who worries that the U.S. is not producing enough college graduates with science degrees, it’s worth wondering exactly why that is. In a new working paper (abstract; PDF), Ralph Stinebrickner and Todd R. Stinebrickner offer a compelling answer: science is hard. Here’s the abstract:

Taking advantage of unique longitudinal data, we provide the first characterization of what college students believe at the time of entrance about their final major, relate these beliefs to actual major outcomes, and, provide an understanding of why students hold the initial beliefs about majors that they do. The data collection and analysis are based directly on a conceptual model in which a student’s final major is best viewed as the end result of a learning process.  We find that students enter school quite optimistic/interested about obtaining a science degree, but that relatively few students end up graduating with a science degree.  The substantial overoptimism about completing a degree in science can be attributed largely to students beginning school with misperceptions about their ability to perform well academically in science.
