Critical thinking

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.

Many news programmes, speeches, or press articles refer to at least one poll. When designed and conducted well, polls are an excellent means of measuring public opinion on a particular topic. Unfortunately, not all surveys are well compiled, relevant, representative, or honest.

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.

When one wants to justify the harm one has done by saying that others have done the same or that this evil was only a reaction to the harm done by someone else, they commit the logical error of appealing to hypocrisy.

It is crucial to realise that while words can be seductive and magnetic, they can also put us in great danger if we let ourselves be carried away by their charms, driven by emotional impulses without reason.

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

"Logic suffers from a great logical fallacy: it believes that reality itself is of a logical nature. If it encounters something that cannot be understood logically, it will claim that this something doesn't exist, but only appears to exist..." (Lucian Blaga, Horizons and Stages)

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.

When we think we are immune to disinformation, we become easy prey for those who manipulate us.

“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.”

We live in a polarised world where conspiracy theories proliferate, but some people are more inclined than others to consume and propagate these theories rather than ignore or demystify them.

When what someone says can be interpreted in multiple ways, we are in danger of coming to an understanding which is different to their intended message.

The questionable cause fallacy, described by the Latin phrase cum hoc ergo propter hoc, is an error of thought which leads us to believe that one event causes another event simply because the two events occur simultaneously. This error can easily be reinforced if the simultaneity of the two events is often repeated.

In everyday life, whether we like it or not, we rely on the information provided by experts or specialists. However, no authority deserves blind trust. When we take someone's word for granted simply because that person is an authority, we make the logical mistake called "appeal to authority."

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