Researchers create an internally-valid, carefully-controlled experiment where they randomly assign you to watch either a happy movie or a neutral movie, and then you are given the opportunity to help the researcher out by staying longer and participating in another study. Do the research results obtained in isolated, carefully controlled laboratory conditions generalize into the real world? įor example, imagine you are a participant in an experiment that looks at the effect of being in a good mood on generosity, a topic that may have a good deal of practical application. Specifically, it accumulates a lot of knowledge on what can happen-under carefully isolated and controlled circumstances-but it has little to say about what actually does happen under the circumstances that people actually encounter in their daily lives. Despite this unique strength, it is also clear that a scientific field that is mainly based on controlled laboratory studies ends up lopsided. This is because only laboratory experiments can clearly separate cause from effect and therefore establish causality. The laboratory experiment is traditionally considered the “gold standard” in psychology research.
