Objectivity in Scientific Knowledge: How Biases Shape Scientific Research

Objectivity is a cornerstone of scientific knowledge, yet its nature and attainability remain contested. This paper examines the epistemology of objectivity in science, exploring how it is defined, pursued, and challenged across philosophical, historical, and social contexts. From rationalist ideals of universal truth to empiricist reliance on replicable evidence, from historical shifts in scientific standards to modern concerns about bias in data-driven research, it investigates whether science can achieve impartial knowledge or is inevitably shaped by human and societal factors. Drawing on thinkers like Popper, Kuhn, and Longino, and analyzing issues like algorithmic bias and peer review, the paper argues that objectivity is not an absolute state but a dynamic process, refined through critical scrutiny and diverse perspectives. In an era of big data and AI, understanding objectivity’s limits is crucial for ensuring science serves truth rather than power.
