Laboratory simulations combine the strengths of lab experiments and field studies while avoiding many of their liabilities. They permit the emotional involvement, the time needed for development of norms and interlocked systems of interaction, and the broad range of variables typical of field settings, yet allow for experimental controls and random sampling of subjects. Of the two basic kinds of simulations (experimental, controlled by the researcher; and free, shaped by participants' behavior), free simulations appear to reflect real experience more closely. To further enhance participants' involvement, organizational simulations can select a meaningful environment and provide an instructor's manual and set of procedures. While simulations have inherent limitations, notably their obvious artificiality, they remain a viable arena for both qualitative and quantitative research, particularly for work on evolutionary theories, social constructions of reality, and systems approaches.
