Critical thinking

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.

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.

The appeal to ignorance (argumentum ad ignorantiam) is an error in thinking which argues that a conclusion is true because there is no evidence against it, or that a conclusion is false because there is no evidence in its favour.

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.

When it comes to conspiracy theories, the public quickly becomes polarised. On one hand, you have the “experts” who reel off reliable information with credible arguments from confirmed cases. On the other hand, there are the “uninformed,” completely disinterested in the subject or outright rejecting it as a myth.

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

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."

The fact that we are able to anticipate most of the consequences of our actions is undoubtedly a blessing. However, we can also allow fear or over-cautiousness to make us anticipate events that are not likely to follow. This edges us toward a common error of judgement: the slippery slope.

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.

Fundamentalist movements, extremist and sectarian religious beliefs, manipulations of the mass of believers, conspiracy theories within religious sects, and other such threats, emphasise the need for critical thinking.

Do your best to present yourself to God as one approved, […] who correctly handles the word of truth. (2 Timothy 2:15)

"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)

In scientific research, sampling is the primary method used when research cannot be conducted on a one-to-one scale. The facts discovered at the level of the sample are presumed to apply in general.

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.
