🤔 Causes of Plagiarism

The problem of plagiarism and academic dishonesty grows more and more each year. According to the research, conducted in 2011 among students, 92% of surveyed stated that they “had or knew someone who had cheated”. Moreover, 59% of respondents stated that they “would intentionally cheat”, and only 41% indicated that they would never cheat because of ethics.

Why does this happen?

The researchers have shed light on this phenomena and here are some statistics:

  • 92% of those who plagiarized stated that they did this because they wanted to get better grades.
  • 83% of those asked said that they cheated because of procrastination; 75% of respondents pointed out that they had not enough time to write an assignment and 33% attempted to cheat due to the overloaded class schedule.
  • 58% of surveyed plagiarized because of lack of understanding and 50% had no or little interest in the subject.
  • 25% of participants believe that anyone cheats without any consequences.
  • 17% interviewees cheated because of peer pressure or think that it does not matter to professor if their paper is plagiarized.

As you can see, among the significant causes of plagiarism are lack of time or laziness, poor academic performance and peer opinion pressure.

✅ Common Types of Plagiarism

Now, when you’re aware what causes plagiarism, let’s talk about its types. Generally, we can divide it in two groups: unintentional and intentional.

When we consider intentional plagiarism, it doesn’t necessarily mean that the paper is copied from the document written by other person. This is only one example of cheating, and the types of plagiarism below may lead to serious sanctions:

  • Direct plagiarism implies word-to word copying of someone else’s work without giving a proper citation, buying or downloading the entire paper and passing as your own. This type of plagiarism may even lead to expulsion.
  • Self-Plagiarism occurs when you submit your previous work, or use parts of previous papers without permission from all professors involved.
  • Patchwriting means that you borrow phrases without using quotation marks. It also occurs when a student replaces the author’s language by synonyms while keeping the same structure and meaning of the original paper.

As for unintentional plagiarism, it can occur when you fail to use the proper citation style or misquote sources. Even 5 words in a wrongly cited phrase may be considered as plagiarism.

☝️ How to Avoid Plagiarism

You may ask: “How can I avoid plagiarism in my paper?” Below, we prepared some tips that would help you to write plagiarism-free papers:

  1. Control your time. As it was mentioned above, procrastination and tough class schedule may lead to plagiarism. To avoid this, don’t put off your tasks until tomorrow. Find out more about time management techniques and choose one that would work best for you. Check this post to learn how to study effectively.
  2. Cite while you write. Get in the habit of citing sources in full as you write your paper. This would save your time for making a bibliography and decrease risks of improper citation.
  3. Use only trusted sources with which you are completely comfortable. First of all, remember that there are a lot of websites with questionable content and even documents that seem scholarly could be another student’s research paper. Second, you must understand the source and be able to restate the key idea in your own words without referring to the origin.
  4. Understand the difference of various citation styles. As we mentioned above, improper citation may result in plagiarism. Make sure you use only one citation style in your paper, and you know how to use it. Don’t forget to use quotation marks when citing the original.
  5. Use plagiarism checker before you pass your paper to professor. Even if you wrote your paper from scratch, we still advise you to check it with tools we mentioned above. You will see if there are any borrowings and will be able to correct them before your professor would assess your paper and cut the grade because of plagiarism.

Remember that for students, getting caught may mean a failing grade, suspension, or even expulsion, and for professionals the stakes are even higher as one’s reputation may not be so quickly mended.
