Random assignment to conditions in between-subjects experiments or to orders of conditions in within-subjects experiments is a fundamental element of experimental research. Here, instead of randomly assigning to conditions, they are randomly assigned to different orders of conditions.

The upshot is that random assignment to conditionsalthough not infallible in terms of controlling extraneous variablesis always considered a strength of a research design. Randomized Partial Counterbalancing. The sage encyclopedia of communication research methods. This approach also makes sense because once there is an effective treatment, the interesting question about a new treatment is not simply Does it work? but Does it work better than what is already available? This will reassure him that he is equally loved.

Those in a trauma condition and a neutral condition, for example, should include a similar proportion of men and women, and they should have similar average intelligence quotients (IQs), similar average levels of motivation, similar average numbers of health problems, and so on. Thus any difference between the conditions in terms of the dependent variable could be caused by the order of the conditions and not the independent variable itself. Participants in all conditions have the same mean IQ, same socioeconomic status, same number of siblings, and so onbecause they are the very same people. One problem with this approach, however, is the existence of placebo effects. An experiment in which each participant is only tested in one condition.
