Dr. Wissam Bourzak's critical study explores the persistent dilemma of bias versus objectivity within the human sciences. This work delves into the epistemological foundations of disciplines like sociology and psychology, questioning whether a researcher can ever be truly detached from their subject. It analyzes various forms of cognitive and cultural biases that can influence research design, data interpretation, and conclusions. Bourzak provides a comprehensive overview of historical debates and contemporary approaches, offering valuable frameworks for students and academics striving to enhance the scientific rigor and impartiality of their work in a field inherently shaped by human subjectivity.
