ChatGPT, an AI chatbot created by OpenAI, has taken the world by storm since its release in November 2022. Its ability to generate human-like responses has made it popular among students and professionals for various applications including content writing.

However, this has also raised concerns about academic integrity as students may be tempted to use ChatGPT to write their assignments. So can plagiarism detection software like Turnitin detect if an assignment was written by ChatGPT? Let’s find out.

What is Turnitin?

Turnitin is a popular plagiarism detection service used by schools and universities worldwide. It compares the submitted work against its extensive database of webpages, academic journals, books, and student paper submissions to check for similarities.

Turnitin generates an originality report highlighting text similarities found. It also gives a percentage indicating how much of the submitted content matches existing sources.

In April 2023, Turnitin introduced AI writing detection capabilities across its several products.

Can Turnitin detect ChatGPT?

Yes, Turnitin can detect content generated by AI tools like ChatGPT to a large extent.

In April 2023, Turnitin released an update to combat the growing use of AI text generators like ChatGPT for academic submissions. Their systems can now identify AI-generated text with high accuracy.

More than 2.1 million teachers and 11,000 educational institutes and universities will benefit from this updated feature that ensures the quality work of 62 million students.

How does Turnitin detect content created by ChatGPT?

Writing pattern analysis: Turnitin looks for peculiar writing patterns and styles characteristic of AI models like overuse of filler words, repetitive structures, etc. that differentiate them from human writing.

Content comparisons: The content generated by ChatGPT is compared against Turnitin’s massive databases to identify probable matches.

Metadata checks: Turnitin looks for authorship metadata linked to AI models.

AI pattern recognition: Advanced algorithms identify patterns like content inaccuracies, lack of citations, etc. that are common in AI-created text.

Constant updates: Regular updates ensure Turnitin stays on top of new developments in AI language models.

Turnitin claims over 98% accuracy in detecting writings from ChatGPT and other AI tools.

How Does Turnitin Work?

  • Students submit their written assignments to Turnitin via the class portal.
  • Turnitin matches text in the assignment to text in its databases of content sources using pattern recognition algorithms.
  • It flags areas of overlap and generates an originality report.
  • The report highlights text matches found and provides a percentage similarity score.
  • Instructors review the Turnitin report to determine if plagiarism has occurred.

Turnitin merely detects text similarities. The final decision on plagiarism rests with instructors based on the originality report and their assessment.

Limitations of Turnitin in detecting ChatGPT

However, Turnitin isn’t foolproof. There are scenarios where Turnitin may fail to detect ChatGPT-generated text:

  • Works based on niche topics may not have enough matchable content in the Turnitin database.
  • Smaller AI-generated portions in otherwise original submissions.
  • The AI model may be fine-tuned or trained on specific topics or the student’s past submissions, making detections harder.

So while Turnitin can pick clear cases of using ChatGPT for entire submissions, it may miss instances where ChatGPT is used discreetly along with original content.

Can you outsmart Turnitin?

Yes, it is possible to outsmart Turnitin on the surface, but doing so comes with significant risks and challenges.

Turnitin now employs advanced AI capabilities on top of its extensive database to detect text matches. Its algorithms are constantly updated to identify patterns indicative of plagiarism, including paraphrasing. Outsmarting it has become progressively difficult.

Any tactics like using esoteric sources, translating text to other languages or paraphrasing heavily could seem like they work initially. However, doing so without citations is still considered academic dishonesty.

Even if you avoid verbatim matches, Turnitin can flag paraphrased portions as potential plagiarism. Educators also closely review flagged submissions and can identify when a student’s writing style doesn’t match previous work.

The consequences of getting caught trying to outsmart Turnitin outweigh the perceived benefits. Plagiarism allegations can result in failing grades, disciplinary action, reputational damage, or even expulsion. This high-risk approach runs counter to the principles of academic integrity.

What Percentage Of Similarity Is Unacceptable In Turnitin?

There is no definitive rule on what percentage of similarity is automatically considered unacceptable across all institutions and assignments.

Turnitin generates an ‘originality report’ showing text matches found, but final determinations of plagiarism depend on institutional policies and instructor discretion.

However, some general guidelines are:

  • A similarity score of under 15% is typically acceptable. Minor high matches could be quotes or commonly used phrases.
  • Between 16-40% raises concerns of potential plagiarism depending on the nature of matches. Further review may be needed.
  • Over 40% similarity suggests heavy plagiarism. However, instructor judgment based on the matched sources is important.
  • For crucial assignments, some institutions take a stringent view and go as low as 10% similarity.
  • For large assignments, higher matches such as 30% could be flagged if plagiarism seems deliberate.
  • Matches with current student papers or questionable internet sources face more scrutiny.

So an acceptable Turnitin percentage depends on factors like assignment type, institutional policies, instructor expectations, and the quality of flagged matches.

While high scores like 60%+ would nearly always be unacceptable, lower scores like 20% may be okay if matches aren’t extensive text copies from concerning sources.

How Can Instructors Detect the Use of Chat GPT?

Here are some points that instructors can use to detect if students are using ChatGPT for their assignments:

  • Look for changes in writing style and quality that seem unusual for the student based on past work. Writing generated by ChatGPT often has a distinctive style.
  • Analyze the structure of the submitted work. Does it follow an atypical 5-paragraph essay structure or has oddly organized arguments for the student’s level?
  • Assess the vocabulary used. Is it overly complex or sophisticated compared to the student’s normal work?
  • Check for lack of consistent tone or flow in the writing. ChatGPT generated text can often be disjointed when you look closely.
  • Are there anachronisms or factual inconsistencies that seem unusual? ChatGPT can incorporate inaccurate or dated information.
  • See if there are missing citations for facts or sources. ChatGPT does not cite automatically in most cases.
  • Look for overuse of quotations and sources to hit word counts rather than original analysis.
  • Compare plagiarism detection software results to look for anomalies.
  • Ask probing questions and see if the student can meaningfully discuss their submitted work.

How Can Students Use ChatGPT Responsibly?

Here are some tips for students for using ChatGPT responsibly without crossing academic integrity lines:

  • Treat ChatGPT as an assisting tool, not as the main creator.
  • Use it for brainstorming ideas and outlines only. Do your own research and write your assignments.
  • Ask ChatGPT to provide sources or citations rather than full paragraphs.
  • Run short extracts through ChatGPT but do the majority of writing yourself.
  • Never copy ChatGPT’s work verbatim. Paraphrase thoroughly if summarizing concepts.
  • Edit and add your own thoughts and voice to anything generated by ChatGPT.
  • Use citations if you include information provided by ChatGPT.
  • Verify accuracy of information given by ChatGPT using reliable sources.
  • Understand risks around passing off AI work as your own before using it.

How are educators responding to ChatGPT?

Many educators see ChatGPT as a disruptive force in academics. However, instead of banning it altogether, they recommend navigating it responsibly.

Some ways educators are responding:

  • Making adjustments to assignments to test true comprehension of concepts over recall alone.
  • Looking beyond essays and focusing more on research papers, presentations, projects, exams etc.
  • Being open about the existence of AI tools and discussing responsible usage with students.
  • Using AI to supplement teaching, not replace it.
  • Updating academic honor codes for responsible AI use.
  • Embracing AI support tools like citation generators, grammar checkers etc. with oversight.
  • Using plagiarism checkers as deterrents.
  • Frequently changing test questions and assignment topics.
  • Manual review along with plagiarism checking. Looking for changes in writing style and quality.

The consensus is that working with students and using AI ethically leads to better outcomes than banning it outright. Turnitin and other detection tools also act as guardrails.
