What is Peer Review?
✅ Definition:
Peer Review is a process where a scientific article or research paper is evaluated by experts in the same field (peers) before it is published.
📌 The goal is to check the quality, accuracy, and reliability of the research.
📘 In simple terms:
You write a scientific paper → submit it to a journal → the journal sends it to other experts (peers) → they read, analyze, and comment → based on their review, your article is accepted, revised, or rejected.
🎯 Why is Peer Review important?
-
✅ Ensures scientific quality and credibility
-
✅ Detects errors, plagiarism, or misleading data
-
✅ Helps improve the paper before publication
-
✅ Prevents false information from being published
-
✅ Maintains the reputation of scientific journals
🔄 How the Peer Review process works:
-
Author submits the manuscript to a scientific journal.
-
Editor checks if it fits the journal’s scope and format.
-
Peer reviewers (experts) are selected to:
-
Read and evaluate the research
-
Check methods, data, results, and conclusions
-
Provide a written review with suggestions
-
-
Based on the reviews, the editor decides:
-
✔️ Accept the paper
-
📝 Request revisions
-
