What Is Wikipedia and Who Created It?
Wikipedia is a free, open-access online encyclopedia that covers almost every subject imaginable today. Jimmy Wales and Larry Sanger launched the site in January 2001 as an open editing experiment. The nonprofit Wikimedia Foundation now owns and hosts the platform, though it never writes any articles itself.
Anyone with an internet connection can create a free account and begin writing new pages. There is no formal editorial board that verifies facts before an article gets published online. This open structure makes Wikipedia fast to update, but it also leaves nursing content vulnerable to error.
Who Manages and Reviews Wikipedia Pages
Wikipedia depends on a global community of volunteer editors rather than paid subject-matter experts. These editors can add, delete, or rewrite content on almost any page at any time. Some pages use “pending changes” protection, but this feature is applied inconsistently across topics.
Administrators can lock frequently vandalized pages, yet most nursing and health articles remain fully open to editing. Contributors do not need nursing degrees, clinical experience, or peer-review training to add information. An article about wound care could therefore be edited by a student, nurse, or complete stranger.
Common Uses of Wikipedia Today
Students and professionals commonly turn to Wikipedia for the following reasons:
Quick background reading before deeper research begins
Finding key terms and vocabulary for unfamiliar topics
Locating citations listed inside the reference section
Comparing basic facts across many general subjects
Getting a broad overview before choosing a research question
Checking simple details, such as dates or definitions
Nursing students often treat Wikipedia as a map rather than a final destination for evidence. It helps learners understand unfamiliar terminology before they search stronger academic databases for real depth. Used this way, Wikipedia saves time without replacing the deeper, evidence-based reading that nursing coursework ultimately requires.
Primary, Secondary, and Tertiary Sources
What Makes Wikipedia a Tertiary Source - Wikipedia is best classified as a tertiary source because it summarizes information gathered from other places.
Primary and Secondary Sources Defined - Primary sources include original clinical trials, patient records, and firsthand research studies. Secondary sources include textbooks, systematic reviews, and meta-analyses that interpret those primary findings.
Why Academic Work Expects More -Wikipedia sits above both categories because it compiles summaries drawn from primary and secondary materials together. Academic nursing assignments typically require primary or secondary sources, not tertiary summaries like Wikipedia. Instructors expect evidence-based citations that trace directly back to peer-reviewed clinical literature.
Why Wikipedia Is Not a Credible Source
Several structural weaknesses explain why educators remain cautious about Wikipedia for coursework:
Anyone can edit an article without any credential check
Content can change completely within minutes or hours
Cited sources are sometimes outdated, biased, or missing entirely
Vandalism and factual errors can remain unnoticed for months
No formal peer-review process exists before publication
Popular topics attract more edits than rare medical conditions
Anonymous contributors make it difficult to judge real expertise
Promotional or biased content occasionally slips into medical pages
These weaknesses matter more in healthcare, where inaccurate advice can genuinely affect patient safety. Nursing research demands sources that are traceable, current, and reviewed by qualified subject experts.
How to Create a Wikipedia Page
Creating a new Wikipedia article involves several required steps before publication becomes possible:
Create a free account and verify your email address
Learn Wikipedia's notability rules before drafting any page
Write the article using neutral language and verifiable citations
Submit the draft through the Articles for Creation review process
Wait for volunteer reviewers to approve or reject the submission
New pages about health topics face extra scrutiny because misinformation there carries genuine risk. Wikipedia's medical project maintains specific guidelines requiring high-quality biomedical sources for these particular pages.
How to Cite Wikipedia Correctly
Most nursing programs discourage citing Wikipedia directly, though formatting rules still exist for optional use. In APA style, include the article title, publication year, and the exact retrieval web address. In MLA style, list the article title, website name, publication date, and access date together.
Some instructors permit Wikipedia only for informal notes, never for formal reference lists or bibliographies. Always confirm your specific program's citation policy before including Wikipedia anywhere in submitted coursework.
Style | Required Elements |
APA | Author (if listed), title, “Wikipedia,” year, retrieval URL |
MLA | “Article title,” Wikipedia, publisher, publication date, access date |
Harvard | Wikipedia contributors, article title, year, site name, URL accessed |
How Often Are Wikipedia Pages Updated?
Update frequency varies enormously between popular topics and obscure, rarely visited nursing subjects. High-traffic pages, such as major diseases, can receive dozens of edits within a single day. Niche clinical topics might go months, or even years, without receiving a single edit.
This inconsistency creates real problems for nursing research that depends on current clinical guidelines. A student citing Wikipedia risks referencing outdated treatment protocols that were never properly revised or corrected.
How Accurate Is Wikipedia, Really?
Mixed Results Across Different Subject Areas - Studies comparing Wikipedia against professional references have produced genuinely mixed results across different subject areas. One widely cited nursing study reviewed thousands of references collected from dozens of health-related Wikipedia articles.
What the Reference Study Actually Found - According to a peer-reviewed analysis of health-related Wikipedia references, roughly fifty-six percent of citations traced back to clearly reputable sources.
Accuracy Depends on Topic and Contributors - This finding suggests moderate accuracy for general health topics, though quality still varies widely between individual pages. Accuracy also depends heavily on how many knowledgeable contributors have edited that specific topic. Rare conditions with fewer contributors tend to carry a noticeably higher risk of outdated or incomplete information.
Accuracy Works More Like a Spectrum - Independent fact-checkers have also found that Wikipedia performs reasonably well on well-established, mainstream medical conditions. Newer treatments, experimental drugs, and rapidly evolving clinical guidance are usually where accuracy weakens noticeably. Readers should treat Wikipedia's accuracy as a spectrum rather than a single fixed rating.
Wikipedia vs Britannica vs PubMed vs CINAHL
The table below compares these four resources across the factors that matter most for coursework.
Feature | Wikipedia | Britannica | PubMed | CINAHL |
Editor type | Anyone, volunteers | Paid experts | Researchers | Health librarians |
Peer review | None required | Editorial only | Yes | Yes |
Update speed | Very fast | Slow | Moderate | Moderate |
Best use | Background reading | General overview | Clinical evidence | Nursing evidence |
Citable academically | Rarely | Rarely | Yes | Yes |
Britannica offers professionally edited, expert-reviewed entries, making it more dependable than Wikipedia for general topics. PubMed and CINAHL remain the gold standard for nursing research because both index peer-reviewed clinical literature. Wikipedia still works well as a starting point, just never as a final citation.
Where Wikipedia's Role in Healthcare May Go Next
Researchers are testing whether artificial intelligence could eventually verify Wikipedia's medical claims against live clinical databases. Such a system might flag outdated drug information automatically, rather than waiting for a human editor to notice. If this technology matures, Wikipedia's reliability for health topics could improve significantly within the next decade.
It remains unclear whether academic institutions will ever formally accept Wikipedia as a citable nursing source. Some experts predict a hybrid model, where AI-verified Wikipedia summaries link directly to primary clinical evidence. Until that future arrives, nursing students should keep treating Wikipedia as a helpful starting point only.
Frequently Asked Questions (FAQs)
Why is Wikipedia an unreliable source? Wikipedia allows anonymous editing without any credential verification, so errors and bias can slip through easily. Content also changes constantly, meaning information can shift between the moment you read it and cite it.
Is Wikipedia trustworthy? Wikipedia is reasonably trustworthy for general background information but not for citation-worthy academic claims. Its accuracy depends heavily on how closely a specific page is monitored by active volunteer editors.
Is Wikipedia biased? Yes, Wikipedia can reflect bias because its content depends entirely on which editors choose to contribute. Some topics receive more balanced coverage than others, especially where fewer subject experts participate regularly.
Who is Jeff Tiedrich on Wikipedia? Jeff Tiedrich is an American political commentator and blogger known for viral social media commentary. He is unrelated to nursing or health research, illustrating Wikipedia's extremely broad general-topic coverage.
Why is Wikipedia not credible for students and scholars? Academic standards require peer-reviewed, expert-verified sources, and Wikipedia does not meet that formal verification standard. Most institutions therefore treat it as a starting point rather than an acceptable formal citation.
Is Wikipedia open source? Wikipedia's content is openly licensed, while its underlying software, MediaWiki, is separately available as open-source code. This openness allows anyone to reuse content, provided they follow the required attribution rules.
Does Wikipedia charge for publications? No, Wikipedia remains completely free for both readers and contributors to use or edit. Voluntary public donations keep the Wikimedia Foundation and its Wikipedia platform running smoothly worldwide.
Final Thoughts
Wikipedia remains a useful starting point for nursing students exploring unfamiliar topics or clinical terminology. Its open-editing model makes it fast, current, and easy to access from anywhere in the world. However, that same openness prevents it from meeting the strict evidence standards nursing research requires.
Databases like PubMed and CINAHL should always replace Wikipedia when citing formal academic work. Students who understand this distinction can use Wikipedia wisely without risking their credibility or academic integrity. Used correctly, it builds curiosity and confidence before deeper, evidence-based research even begins. Treat it as a map toward better sources, never as the final research destination itself.
