Rationalisation is a concept extensively used by Max Weber to refer to the multifaceted process by which modes of precise calculation, efficiency-oriented organisation, and action based on abstract rules, laws, and procedures increasingly come to dominate the social world, replacing more traditional, emotional, or value-driven forms of social organisation and behaviour. This process is a central theme in Weber's analysis of modernity and is closely linked to the rise of bureaucracy, capitalism, and science. Rationalisation involves a shift towards systematic thinking, the application of reason and logic to social life, and an emphasis on predictability and control through formal structures and procedures. While it has led to advancements in technology, efficiency, and administration, Weber also cautioned about the potential negative consequences of rationalisation, such as the disenchantment of the world and the dominance of impersonal bureaucratic structures.
