What Are We Talking About When We Talk About Scientific Objectivity?

Abstract

Philosophers of science often suggest that the key feature of scientific research is striving for objectivity and that we should evaluate scientific practice by whether it is objective or not. In this paper, we will analyze several definitions of scientific objectivity to illustrate the complex meaning of this term and examine its role in evaluating scientific practice. First, we will introduce Lorraine Daston and Peter Galison's standpoint concerning the historical connection between the genesis and development of scientific objectivity and the practices of visual representation in the research practice of the 19th and 20th centuries. We will accomplish that by outlining the process of establishing scientific objectivity as an epistemic virtue and a vital feature of the "scientific self ". Subsequently, using Heather Douglas and Mar-ianne Janack's conceptual analysis of scientific objectivity, we will show that scientific objectivity is characterized by an "irreducibility of meaning" and an "endemic instability" caused by the overuse of metaphors in defining this concept. In the final section, in light of contemporary problems such as the crisis of reproducibility, we examine to what extent philosophical definitions help test the objectivity of scientific practice and point to an intriguing attempt to define "objectivity for the research worker" using the model proposed by Noah van Dongen and Michał Sikorski.
