In 2021, 29% of the French believed that the Earth could be flat, according to an IFOP survey. Some beliefs persist despite the accumulation of contrary evidence, taking advantage of information taken out of context or a selective interpretation of facts.
The spread of received ideas and conspiracy theories is not coincidental. Behind this phenomenon are powerful cognitive mechanisms that fuel distrust, distort judgment, and blur the line between serious information and dubious assertions. Social media, with their frenetic pace, serve as an echo chamber for these beliefs, making the distinction between true and false increasingly blurry.

Why conspiracy theories are so appealing: understanding the mechanisms and beliefs
At first glance, one might think that logic and reason are enough to protect us from conspiracy theories. However, even the most methodical minds are not immune. Gerald Bronner, Richard Monvoisin, and Daniel Kahneman have established that our brains constantly apply cognitive biases that filter reality without our awareness. The confirmation bias, for example, leads us to favor what reinforces our convictions. As for the Dunning-Kruger effect, it gives some individuals disproportionate confidence, hindering any questioning.
Then, there is information overload. Faced with a mass of often contradictory data, our vigilance weakens. Intuition then takes over, but as shown by Daniel Simons and Christopher Chabris, intuition often proves misleading when judging the reliability of complex information. Even memory, far from being infallible, can be manipulated. The work of Elisabeth Loftus has highlighted this: a memory is never completely reliable.

In this context, it is not surprising that unfounded beliefs, pseudosciences, and fake news take root. Critical thinking requires effort and constant vigilance against mental traps. The resources offered on skepticnorth.com emphasize the importance of questioning one’s intuitions, detecting cognitive illusions, and stepping back from our perceptions. This is how we manage to distinguish between what is factual and what is belief.
How critical thinking is developed in the face of misinformation and received ideas
Developing a critical approach is not improvised. It is a patient learning process, made up of trials, errors, and questioning. Subjecting information to source verification, cross-referencing evidence, questioning the coherence of an argument: these are all actions that anchor rigor in daily life. The Scientific Council of National Education (CSEN) encourages examining the credibility of a claim, the reliability of the source, and the solidity of the reasoning. This control work does not stop at the public sphere: it applies equally to private exchanges and professional decisions.
Media and information literacy begins in childhood, providing tools to decipher the continuous flow of news and opinions. Knowing how to suspend judgment, recognize uncertainties, and practice metacognition: these skills foster a humble posture, open to doubt and reflection. Zetetics, inherited from the work of Henri Broch and Richard Monvoisin, offers a structured method for questioning claims, relying on science rather than intuition or emotion.
Adopting a critical mindset does not mean contesting everything by principle. It involves examining facts, tracking one’s own biases, and accepting contradiction. Tools from science and philosophy help exercise this vigilance: evaluate, doubt, reformulate, and then decide. This intellectual exercise forges a clear-sighted citizenship, capable of discerning between the plausible and the illusory.
Concrete examples to exercise discernment in daily life
In everyday life, critical thinking sharpens away from university benches. When faced with viral information on social media, it is better to take the time to inspect the source. A sensational headline, a decontextualized image, a quote attributed without verification: these signs should immediately raise caution. Here are some reflexes to adopt to untangle truth from falsehood:
- Evaluate plausibility: a claim that is too sensational should be verified.
- Look for evidence: any solid information is based on tangible facts.
- Measure the coherence of the argument: a logical reasoning withstands critical analysis better.
To sharpen this intellectual self-defense, some rely on playful tools: role-playing games, analyses of fictional scenarios, or collective “debunking” exercises. Neuropsychologist Albert Moukheiber encourages questioning the illusion of knowledge: “Am I capable of explaining what I believe I know?” A simple exercise consists of reformulating the claim in one’s own words and then looking for concrete evidence to support it.
Zetetics also offers a practical method. It involves distinguishing testimony from proof, separating what seems credible from what is extraordinary, and identifying interpretative biases. Even during a family gathering or a work discussion, one can ask: “What is actually established?” or “What data is this decision based on?” Adopting this stance does not mean suspecting everything, but cultivating clarity and accuracy in reasoning. Day after day, methodical doubt becomes a citizen reflex, a way to pave the way for a more enlightened debate and to stand up against the received ideas that become ingrained in our habits.
In this silent battle against illusions, every question asked, every doubt expressed, pushes back the shadow a little further and redraws the contours of sharpened thought. Critical thinking, far from being an elitist posture, emerges as the most reliable weapon for navigating the jungle of ephemeral certainties.
