Science is the practice of falsifying models using systematic observations. In psychology and related sciences, these models are theories about why a person or group engages in a behavior(s). Falsification is a high threshold for models: If any prediction of a model is not supported, the entire model is discarded. While study results that are consistent with a model prediction increase our confidence that the one model prediction is supported, every single prediction of the model must hold true for the model to be considered supported. Thus, the most important studies are studies that falsify predictions of a model. Finally, a model is never “proven”, because a model prediction could always be falsified by the next study. Models are “supported” or “falsified”. This literature (below) represents some of the important model falsifications that have occurred in sex film science.
