Reporting bias

Reporting bias occurs when only a select amount of information is shared, while other information is supressed. It can occur in data collection when participants in a study choose to not report certain information (e.g. not report that they’ve previously smoked cigarettes when asked if they’ve ever smoked) and in dissemination of research findings when researchers choose only to report certain results from a study (e.g. only reporting results that back up their hypothesis).
