Monocausal

Monocausal is an adjective used to describe explanations or accounts that attribute an outcome to a single cause, often treating that cause as the primary driver and downplaying or excluding other contributing factors. In intellectual discourse, monocausal explanations are contrasted with multicausal or multifactorial analyses, which acknowledge that many factors can interact to produce a result.

Usage and examples: In medicine, a monocausal perspective might frame a disease as arising solely from one agent or behavior, for example suggesting that a specific toxin directly causes a condition. While single factors can have strong effects, modern epidemiology and public health emphasize multifactorial causation, recognizing how genetics, environment, and interactions among factors shape risk. In social science, monocausal claims—such as attributing crime or poverty to a single factor like unemployment or discrimination—are often criticized for oversimplification, because social outcomes typically emerge from complex, interrelated causes.

Limitations and implications: Monocausal explanations can be useful as heuristics or starting points, especially for action or communication, but they risk obscuring important context, interactions, and feedbacks. They may misguide policy by overlooking structural factors, cumulative risks, or the role of multiple contributing factors. In research, reliance on monocausal narratives can hamper the discovery of effective, holistic interventions.

Related concepts: The term is discussed in philosophy of science, epidemiology, and sociology, with contrasts to multicausal or multifactorial reasoning. The notion of necessary versus sufficient causes and the sufficient-component cause (causal pie) model are often invoked to analyze when a single factor is adequate or when combinations are required.
