scientific emphasis on causal explanations
a basic principle of science is that every event in the universe has a cause and they can be explained using general laws (hard determinism)
knowledges of these causes and laws is important as it allows scientists to predict and control events in the future.
e.g. in chemistry x chemical + y chemical= z reaction
this why lab experiments (with highly controlled variables) are often used by researchers to try to control and predict behaviour.
highly controlled lab studies in psychology increase the scientific standing of psychology as a discipline
