Atheoretical means “not based on or connected to any specific theory.” In research or academic contexts, if something is described as atheoretical, it means it does not rely on, reference, or develop a particular theoretical framework or set of guiding principles. Instead, it may simply present data, observations, or findings without attempting to explain them using established theories. For example, an atheoretical study on eating habits might collect and report data about what people eat, but it would not interpret the results using psychological or nutritional theories about why people make those choices.
