Common research methods have significant limitations. Web crawls, for instance, usually don't realistically simulate user activity and experiences. Lab studies often involve simplified systems that don't generalize to the real world. Surveys yield self-reported data, which can be very unreliable.
Rally studies, by contrast, reflect real-world user activity and experiences. In science jargon, Rally enables field studies and intervention experiments with excellent ecological validity.
