Plagiarism and Academic Integrity

Using others' work properly

Plagiarism is presenting others' words, ideas, or data as one's own without proper attribution. Academic integrity requires accurate citation of all sources, quotation marks for exact wording, and genuine paraphrasing. Forms of plagiarism include verbatim copying, mosaic or patchwriting, and self-plagiarism — reusing one's own prior work without disclosure. The credibility of academic scholarship depends on consistent adherence to these principles.

What Is Plagiarism?

Plagiarism occurs when someone presents another person's words, ideas, data, or creative output as their own without clearly acknowledging the source. It can be deliberate — direct copying — or unintentional, arising from poor note-taking or misunderstanding paraphrase rules. Academic communities treat plagiarism as an ethical violation, an infringement of intellectual property, and an act that undermines trust in scholarship. Regardless of the extent of the contribution, any original expression or idea taken from another author must be attributed.

Main Types of Plagiarism

There are three principal types of plagiarism. First, verbatim copying: reproducing a source text word-for-word without quotation marks and a citation. Second, mosaic plagiarism or patchwriting: rewriting passages by substituting synonyms or stitching together fragments from multiple sources without adequate attribution. Third, self-plagiarism: reusing a substantial portion of one's own previously published work in a new publication without disclosing that prior appearance to readers or editors. In all three cases, academic integrity norms are violated, regardless of intent.

Concrete Example: Correct and Incorrect Use

Suppose a researcher wants to draw on the sentence: "Science is built on systematic skepticism." Incorrect use: inserting this sentence into a paper without quotation marks or a citation. Mosaic misuse: writing "Scientific knowledge rests on systematic doubt" with minimal changes and no attribution. Correct use — direct quotation: enclosing the exact wording in quotation marks and providing an in-text or footnote citation. Correct use — paraphrase: re-expressing the idea entirely in one's own words and adding a citation. The presence and adequacy of attribution is the decisive criterion in every case.

Common Pitfalls and How to Uphold Academic Integrity

A common misconception is that paraphrasing removes the need for citation; in fact, the source of any idea must be acknowledged regardless of how it is expressed. Another pitfall is overestimating the scope of common knowledge: contested or original findings always require a source. Regarding self-plagiarism, reusing method or results sections from prior papers without notifying editors is ethically problematic. To avoid these errors: take detailed notes, practice writing away from sources, use a reference manager, and consult your supervisor or your institution's academic integrity guidelines whenever in doubt.
