 While this area first came to prominence in the so-called science wars of the 1980s, attending to social dimensions of science has brought a number of topics to philosophical attention. The phenomenon of Big Science has encouraged philosophers to consider the epistemological significance of such phenomena as trust and cognitive interdependence and the division of cognitive labor. The increased economic and social dependence on science-based technologies has prompted attention to questions of inductive risk and the role of values in assessing hypotheses with social consequences. The controversies over health risks of certain vaccines, over the measurement of environmental pollution, and over the causes of climate change have expanded philosophy of science from its more accustomed areas of logical and epistemological analysis to incorporate concerns about the communication and uptake of scientific knowledge and the ethical dimensions of superficially factual debates.
