Objectivity and science: Critical analysis of how cultural biases are woven into studies

Feminist science studies is a particularly important field as invisible biases from popular culture are woven into hypotheses and research without notice. Let’s unpack this taking the scientific method into account. When we practice science we draw from observation to formulate our research agendas and hypotheses. We then conduct a repeatable experiment and interpret our data. As noted by the Association of American Colleges and Universities (1999) there are several points in which our own social, political and/or personal interests can affect the data we produce;
 Social, political or personal interests can affect:
   —how scientists set priorities for scientific investigation;

   —what questions are posed about a topic;

   —what explanatory framework or theory frames a scientific study;
   —what methods are used;

   —what data are considered valid and invalid;

   —how data are interpreted;

   —how data in one study are compared to data in other studies;
   —what conclusions are drawn from the analysis of scientific data; and
   —what recommendations are made for future studies.
                                                            (AAC&U, 1999:5)
By pointing out ways in which science can be influenced by societal agendas and ideals, feminist science scholars aim to address and deconstruct the belief that science is wholly objective.
Furthermore, the way we are taught to write science works to covers up any ideas that subjectivity exists within the field. When we write laboratory reports and manuscripts, we often include phrases like The findings suggest… and Increased ____ indicates _____. These phrases strip the context and ourselves out of our findings – effectively diminishing the idea that personal interests may be inadvertently sewn into the science we produce; they make it appear as if our findings are concrete and not just a possible explanation or interpretation that we made in our head (Hubbard 2001).“Feminists must insist that subjectivity and context cannot be stripped away, that they must be acknowledged if we want to use science as a way to understand nature and society and to use the knowledge we gain constructively” (Hubbard 2001: 158).
The theories that we create also work to influence our scientific observations and hypotheses. In other words, “Rather than experimental and observational data being the determinant of the course of science, theories determine what evidence is looked for and what evidence is taken seriously” (Wyer et al. 2001: xxi). For example, evolutionary theory shapes the questions we may ask in a study (ie. do men and women differ in their sexual selection), as well as what data we select to observe in the study and how we interpret that very data. 
We must also be critical of the language we use to produce science. Language is a tool we use to communicate our thoughts and ideas. While language is great, the terminology we have is limited. The language we use is constructed and shaped by cultural beliefs; in other words, we only have and make words for objects we need words for. As argued by Luce Irigaray, the terminology used in the sciences has been affected by dominant male voices in the field: the language used is not neutral but instead androcentric (Irigaray 1989). Scientific language codes the male as the assumed norm and embodies a “systematic gender bias” (Irigaray 1989; Wiley 2009). “From this point of view, science — the real game in town — is rhetoric, a series of efforts to persuade relevant social actors that one’s manufactured knowledge is a route to a desired form of very objective power” (Haraway 1988: 577).
To bring these ideas of how subjectivity is woven into science into context, let’s examine a few studies, which have used scientific methods to justify and “prove” what we now deem to be inaccurate sexist and racist beliefs. In the late 1800s, many “scientists” held the belief that women were not as intelligent as men – they also found that on average, the women they knew tended to reflect this belief. Paul Broca, used anthropometry, the measurement of the human body, to determine reasons for this ‘observation’ (Gould 1980).[1] Broca measured the weight of 292 male brains and 140 female brains, and found, on average that women’s brains tended to weigh less than men’s brains – as a result the smaller brain size must help explain why women are intellectually inferior beings (ibid).[2] Other scientists offered alternative explanations for his findings, like difference in stature. Broca responded to these critiques:
“We might ask if the small size of the female brain depends exclusively upon the small size of her body. Tiedemann has proposed this explanation. But we must not forget that women are, on the average, a little less intelligent than men, a difference, which we should not exaggerate but which is, nonetheless, real. We are therefore permitted to suppose that the relatively small size of the female brain depends in part upon her physical inferiority and in part upon her intellectual inferiority” (Gould 1980: 152).
As all of the data that Broca collected were objective and concrete, and his methods were flawless and scientific. Scientists of the time, like Gustave Le Bon, found it impossible to disagree with Broca’s conclusion:
“In the most intelligent races, as among the Parisians, there are a large number of women whose brains are closer in size to those of gorillas than to the most developed male brains. This inferiority is so obvious that no one can contest it for a moment; only its degree is worth discussion. All psychologists who have studied the intelligence of women, as well as poets and novelists, recognize today that they represent the most inferior forms of human evolution and that they are closer to children and savages than to an adult, civilized man. They excel in fickleness, inconstancy, absence of thought and logic, and incapacity to reason. Without doubt there exist some distinguished women, very superior to the average man, but they are as exceptional as the birth of any monstrosity, as, for example, of a gorilla with two heads; consequently, we may neglect them entirely” (Gould 1980:153).
When we reflect on Broca’s work today however, the subjectivity that was woven into his clearly scientific study is more evident: the assumptions that were made in formulating his hypotheses and research question, as well as his interpretations of the data. Today, this research is dismissed – we know that brain size is not correlated to intelligence (after all, to accept this would mean that were are inferior to elephants and other large animals); furthermore, we know that Broca’s observation of women’s inferior abilities were not biological, but instead attributed to restricted education and gender roles.



[1] Similar studies and observations were made between white men and men of color at the time. And of course, white men used science to “prove” that they were also superior to men of color to justify excluding them from positions of power in society.
[2] Today, we know that women’s brains on average do tend to be smaller than males, however we also know that women’s brains are denser than male’s brains (interestingly, no one has posited that the density of brains is correlated to intellectual superiority….).
