Wikipedia has its own rules for editing topics related to medicine and psychology. That's because Wikipedia is one of the leading websites people turn to for health information, more so than websites from the National Institute of Health, World Health Organization, or WebMD.

Poor information about health topics can have real-world consequences for readers who don't always bring the amount of skepticism they should to Wikipedia's health information.

That's why MEDRS exists. MEDRS is short for "Medical Reliable Sources," and it's the set of guidelines for identifying reliable sources in medicine and psychology. These standards can make it challenging for student editors to contribute to these topics.

This orientation will give you an overview of those requirements, which are available in detail by typing the Wikipedia shortcut WP:MEDRS into Wikipedia's search bar.
