Critical thinking

Western societies pride themselves on their access to information. Compared to our predecessors, we seem to be the most informed generation to have ever lived on Earth. However, paradoxically, the more data we have access to, the harder it is to determine what is true and what is false.

From television stories to personal experiences, we live in a world where honesty seems to be an increasingly rare commodity and suspicion and scepticism become protective shields.

The biased sample is a kind of unrepresentative sample, either for quantitative reasons (as is the case with the too-small sample), or for qualitative ones, when its structure does not represent the structure of the real population that is the object of the research.

"Happiness is not in the mere possession of money; it lies in the joy of achievement, in the thrill of creative effort." (Franklin Delano Roosevelt, US President)

From an early age I learned, from the advice of adults or from my own experiences—and sometimes the hard way—the relationship between cause and effect. It's simple: if you touch the hot oven door, you’ll get burned! Subsequently, I discovered that there are a multitude of pressing uncertainties all around us in daily life. To figure out what actually causes the things that...

Even if we have not been to Eden, the longing for innocence draws us back to a time when we had not yet tasted the forbidden fruit.

Conspiracy theories and fake news are not the same thing, although the two categories have much in common.

Arguments must be convincing and, in order to convince, they must be valid—the minimum requirement of persuasion.

“Yeah, I understand what you’re saying about Christianity. I’ve been there, a long time ago, but now that I’ve moved on, I have a different relationship with the universe and things are going much better for me on all levels.”

When we consider that a conclusion is founded only if a lot of people consider it true, we fall into the trap of the argumentum ad populum or the appeal to popularity.

A circular argument is an argument forming part of a thesis which has not been established, but still needs to be argued for.

No one has ever seen a thought, not even a neurosurgeon. However, today we know more about the way we think than what we were able to visualise, yet still less than we would like to know.

Even the most rigorously researched statistics are not immune from misinterpretation, and they can often be used in a way that obscures the truth.
