The author discusses some of the practical limitations of scientific inquiry that effect objectivity (finances, countless variables in the natural world that complicate things, outdated methods or equipment, etc.), but perhaps more importantly, the ways in which value judgements do come into the interpretation of data. This isn’t to say that if science isn’t perfectly objective, the whole thing is a big conspiracy and we should all forget about this whole science thing. I certainly wouldn’t advocate that stance!
Instead, it seems to me (as a non-scientist) that it is a call for scientists, and those interested in science, to be aware that scientists, like everyone else, are products of culture, particular organizations and institutions, their particular time and place in history, etc., and as such, carry cultural baggage, make assumptions, take certain things about the world for granted, and make value judgements based on their own prejudices.
Of course, the idea that true objectivity doesn’t (and perhaps, shouldn’t) exist isn’t only relevant for scientists. This little blog here is my personal attempt at challenging my own assumptions about the world. I try to seek out new information that gives me a more ‘objective’ view of reality, but at the same time, it is unrealistic to believe that I can ever actually be completely free of biases and certain cultural values, no matter how hard I try. I also wouldn’t really want to give up all of my cultural values because they do serve a useful purpose in life. Humans live with other humans, and as a way to communicate and create social bonds and cohesion, it is necessary to have some common ground with others, a sort of default setting of background information so we don’t have to be explaining ourselves to death all the time!
What do we really mean when we talk about objectivity anyway? What does it mean to be ‘objective’ and why does modern Western culture value this trait so highly? In what situations might it be undesirable to try for objectivity? How can we strike a balance between objectivity and the inescapable reality of personal and cultural biases and assumptions?
For more on this topic, there is also a follow-up post here discussing why, in fact, it isn’t desirable for science to be completely objective, which is also worth reading.
