In his column “Scientific competency is essential to the liberal arts” Roman Goldstein essentially attacks humanities and social science (HSS) majors as scientifically incompetent. He is both offensive and incorrect. Despite the fact that Washington University has created a system in which HSS majors do not really take the general sciences, these students manage to excel scientifically nonetheless.
Roman does correctly state that most HSS majors do not take the science classes geared for science majors. A quick look at the science-major track offers a clear explanation why non-majors do not usually take these classes, which consist mostly of introductory biology, chemistry, and physics: they are primarily pre-med weed-out classes. In an earlier column by Roman this year, he discourages the incoming freshmen from being pre-med because of these same classes he is now advocating taking! He writes,
“About two-thirds of students say that grades in pre-med courses don’t accurately reflect their understanding of the material….These classes are foremost designed to weed you out, as my professors admitted. Thus, I was tested on material barely covered in either lecture or the textbook [and] did chemistry labs that required no understanding of the chemistry behind them….”
If Roman describes the pre-med track as such, why should HSS majors be a part of such a system? In taking science classes, the goal is not to be weeded out and to take exams that test what we do not know. Rather, the goal for the HSS major is truly to learn about science and its applications. Unfortunately, the science classes of the pre-med track do not provide an environment conducive to reaching this goal.
Also, Roman hugely underestimates the importance of the non-major courses. If Roman insists that “you don’t need Shakespeare in daily life,” then you certainly don’t need to understand the molecular structure of tetrahydrofuran either. Unlike the major courses, non-major courses teach us the relevant scientific aspects of daily life. For example, Human Biology gives students a chance to explore and understand the systems of the body and their functions. The class teaches students why someone hyperventilating breathes into a brown bag or why focusing on something in the distance gives tired eyes a rest. In addition to this applicable information, the process of diagnosing a disease does require critical thinking. Like Human Biology, many of the non-major classes sharpen the mind.
Roman has also overlooked the power of HSS classes like history and economics to exercise critical thinking. As a firm believer in a liberal arts education, I too believe in the necessity of taking science classes in order to develop critical thinking. I disagree, however, that science is the only way to create the necessary skepticism to which Roman refers. Critical reading and writing can also provide a critical framework through which to view our government and society.
And does the critical thinking provided by science-major classes really enable us to hold better, more well informed conversations about genetically modified products or cloning? Roman seems to have confused the average HSS major with the average American when he writes, “The average HSS major can’t form an informed opinion on these products because s/he doesn’t understand genetics and can’t follow the scientific debate on the subject.” As students at a very selective liberal arts university, most here are more than decently knowledgeable in science and math, since they usually enter Washington University with a year or two of high-level science and math under their belt.
However, the university does need to create a curriculum that allows non-science majors to take the general science classes. It needs to create general chemistry, biology, and physics courses that are not designed to make us fail but that emphasize learning instead. This thought is great, but the reality is that this university’s goal is to breed doctors to increase its research on genetics, rather than to educate the general student body in the areas of biology and chemistry. But that’s a whole other issue.
The important factor Roman points out is the need for scientific competency. But instead of underestimating the competence of HSS majors or demanding that the school make them take “24 credits of rigorous scientific classes,” how about offering science classes not designed to weed them out? And more importantly, how about trusting the fact that previous knowledge, a few non-major science courses, and an HSS major do indeed make knowledgeable, participatory citizens?
