What differentiates a fact from mere opinion? Are there facts that are better than others? And what makes up for the difference?
About What’s in our Facts?
Just like the ingredients of food, the ingredients of scientific facts shape people’s lives. This is because ranges of normative criteria and definitions precede scientific fact production. For instance, poverty research is based on a normative definition of poverty, that subsequently shape poverty policies. And testing the efficacy of an antidepressant is based on normative definitions of both efficacy and depression, that subsequently shape depression treatments. This is not to say, though, that facts are mere opinions. Tonight, emeritus professor of philosophy, history and sociology of science Trudy Dehue argues that some facts can be better than others, not so much because they represent a pre-given reality, but because they are more thoroughly warranted in a philosophical, ethical and social sense. Stated differently, apart from statistical precision ‘deliberative precision’ constitutes the difference between ‘facts’ and ‘opinions’. This implies that researchers need much more time for thorough reflection as well as open democratic knowledge-production than is most often granted to them.
