Research Principles refer to the fundamental guidelines, ideals, and ethical considerations that underpin the conduct of systematic inquiry in social science. This category encompasses core tenets that ensure the quality, integrity, and trustworthiness of research findings. Key principles include objectivity (striving for impartiality and freedom from bias in data interpretation), value neutrality (Max Weber's emphasis on sociologists setting aside personal values during research), reliability (consistency of measurement), validity (accuracy of measurement), and replicability (the ability for other researchers to repeat a study). It also covers ethical considerations such as informed consent, protection of participants' privacy, and responsible data management. These principles guide researchers in formulating hypotheses, designing studies, collecting and analysing data, and drawing conclusions, ensuring that sociological knowledge is produced through rigorous, transparent, and ethical means. Concepts like the Hawthorne effect (changes in behaviour due to being studied) and the need for applied social research (aiming to solve problems) also fall under this domain, reflecting the practical and methodological considerations in sociological investigation.
