One of the basic principles of determinism (which is in line with scientific beliefs) is that allbehaviour has a cause.
What does the basic principle of determinism allow researchers to do
It allows researchers to manipulate an IV within a lab experiment setting in order to investigate its effect on the DV, provided there is a high level of control maintained over extraneous variables. If there are any changes in the DV, they can be attribute to the IV
What does ensuring changes in the DV being from the IV allow
It allows us to establish a cause and effectrelationship between the IV and DV. Therefore, this allows us to predict/control human behaviour
