“Isn’t the AI lying about that?”
AI answers can sound convincing even when they are wrong.
As generative AI becomes more integrated into our daily lives, there have been more and more instances where it boldly spouts “lies” or “nonsense” that seem plausible at first glance.”
So, how can we spot AI’s lies?
This guide explains a phenomenon known as AI “hallucinations” and how to deal with them.
Does AI Actually “Lie”?
First, it’s important to understand that AI isn’t intentionally lying the way humans do.
The phenomenon where errors or falsehoods are mixed into AI’s responses is called “hallucination,” and it occurs for the following reasons:
- Errors in probabilistic predictions (plausible but inaccurate)
- Bias in training data (biased toward certain types of knowledge)
- Lack of contextual information in the question (the AI doesn’t understand it correctly)
In other words, these “untruthful-sounding answers” stem not from “malice,” but from “inherent limitations” in the system.
Three Ways to Spot AI “Lies”
1. Check for Sources or Evidence
When faced with an AI’s answer, ask, “Where did you get that information?”
While some AI systems have the ability to cite sources, at this point, they may still fabricate information to make it sound plausible.
Example: Cases where it presents non-existent research papers or URLs
🔍 Checkpoints: Actually search for the provided URL; look up the author’s name
2. Make fact-checking a habit
Whenever you’re curious about information provided by ChatGPT, Bard, or similar tools, get into the habit of cross-checking it with Google Search, Wikipedia, or other sources.
Be especially cautious with the following types of content:
- Specific information such as history, place names, and people’s names
- Matters related to laws and systems
- Medical and health advice
🧠 Tip: Cross-check with multiple reliable sources
3. Be Skeptical of Answers That Sound “Confident”
Since AI is designed to avoid saying “I don’t know,” it tends to make definitive statements even about things it doesn’t know.
For example…
❌ “XX is absolutely correct!”
✅ “It’s said that XX is the case, but the details need to be verified.”
Keep in mind that just because it’s stated definitively doesn’t mean it’s accurate.
Anyone Can Do It! How to Use AI to Minimize Misinformation
There are steps we can take to prevent AI from “lying.”
- Make your questions as specific as possible
- Include necessary conditions (time period, region, constraints)
- Specify the output format (table, list, with citations, etc.)
🎯 Example: “Please provide a table showing the trends in Japan’s minimum wage from 2023 onward. Please include sources as well.”
Conclusion | How Should We Deal with AI “Mistakes”?
While AI is an extremely useful tool, it’s important to use it while remembering that it is not “all-powerful.”
The ability to recognize falsehoods (information literacy) is an essential skill for those of us living in the coming era.
Develop a critical eye that doesn’t take AI’s answers at face value.
That is the “smart way” to use AI in this new era.
