In a scientific theory, particularly within psychology, a hypothetical construct is an explanatory variable which is not directly observable
. For example, the concepts
of intelligence and motivation are used to explain phenomena in psychology, but neither is directly observable.

Scientific hypotheses and theories (e.g. evolutionary theory, gravitational theory), as well as classifications (e.g. in biological taxonomy) are also conceptual entities considered to be constructs.
