The results of experiments conducted in the laboratory may not well, meaning that the results cannot be applied to real-world situations or to more general populations beyond the participants in the study.

The results may not generalize well. This is one of the goals of good scientific research: can the results be taken to fit more than just the sterile, controlled situations usually found in the research setting. Many times, it's been found, research tends to lack the ability to be placed in a more "natural" setting.
