1. Why fake news is a vital issue in 2025
“Information has become a weapon. Knowing how to read it, analyse it and question it means learning how to defend yourself.”
Fake news is no longer just aimed at the political and social spheres. They attack brands, companies, institutions. A viral rumour can be enough to destroy a reputation that has been patiently built up in a matter of hours.
👉 Training to detect disinformation is no longer a “plus”, it’s a strategic skill.
2. Understanding your own cognitive biases: the basis of intellectual self-defence
Our brain is a wonderful tool… but also a biased machine.
We are all influenced by mental shortcuts. These cognitive biases colour our perception of the world. Spotting them is the first step to better reasoning… and better decision-making.
Some crucial examples:
| 🧠 Bias | 💥 Effect | 🛡️ How to protect against it |
|---|---|---|
| 🎯 Intentional bias | Tendency to see an intention behind any event | Wondering: “Is this really intentional or just chance? “ |
| 🔍 Confirmation bias | Easily believing what supports our preconceptions | Actively seeking opposing viewpoints, crossing sources |
| 🌈 Halo effect | Generalizing a quality or flaw to an entire person or group | Evaluating each item or action independently |
| 🔁 Effect of illusory truth | Tendency to believe a piece of info because it is often repeated | Activate its “system 2” (slow, analytical thinking) |
3. How Social Media Works (and Why It Manipulates Us)
- If it’s free, you’re the product.
- Algorithms seek to capture your attention, not to inform you correctly.
- Filter bubbles reinforce your beliefs, trapping you in echo chambers.
- Social polarization (exacerbated by social media) makes debate impossible.
Tip: Force yourself to voluntarily consult sources of information that oppose your own bias.
4. Learn to Recognize the Information Jungle
For each piece of content, ask yourself this simple question: Which typology does it belong to?
In the era of information overload, knowing how to distinguish information, opinion, and manipulation has become a vital reflex. This table helps you see things more clearly.
| 🗂️ Typology | 🎯 Main objective |
|---|---|
| ✅ Information | Convey a verified fact, based on reliable sources |
| ⚠️ Disinformation | Deliberately misleading to harm or manipulate |
| ❗ Misinformation | Spreading an error or false information without malicious intent |
| 💬 Opinion | Expressing a personal or subjective point of view |
| 📢 Advertising / Propaganda | Influencing behavior or selling an idea/promotion product |
| 🎭 Satire | Entertain, criticize, or denounce through exaggeration or parody |
| 🧲 Clickbait | Attract attention at all costs through misleading or sensationalist headlines |
5. Deepfakes, Generative AI, Bots: The New Challenges
Today, even a trained eye can be fooled:
- Deepfakes falsify images, voices, and videos.
- Bots artificially amplify content.
- AI-generated articles flood the web, often without an identifiable signature.
Clues to detect a deepfake or generated fake news:
- Perfect faces but inconsistencies in pupils, ears, or hands,
- Frozen expressions, strange movements,
- Inconsistencies in backgrounds,
- Overuse of generic phrases (“in the age of”, “it is crucial of…”).
Essential reflex: always cross-reference your sources and activate your critical radar.
✅ Who is the author?
✅ Where does the source come from?
✅ What are other reputable media outlets saying on the subject?
✅ Is it consistent with other known facts?
✅ What is the author’s implicit objective: to inform, sell, manipulate?
Your brain is your best antivirus
“Against fake news, critical thinking is your best firewall. There’s no antivirus for human intelligence: it must be trained, practiced, and activated.”
Critical thinking cannot be bought; it is forged by reading, by comparing ideas, by cultivating nuance, by accepting that you are sometimes wrong. And above all, by refusing to give in to the emotional slant that all opinion manipulators seek.
👊 Become stronger than disinformation. Train your critical thinking today.
