Critical thinking

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.

"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)

"Intelligent, scientifically trained people no longer believe (or can no longer believe) in God."

In our everyday lives we ​​often resort to simply repeating what has been said or done before. But not everything that is old is authentic or correct. When we refer to tradition with full confidence that the way it was understood and acted on in the past is self-evident, we are committing the logical error of appealing to tradition, or false induction.

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

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.

Many of us probably know at least one manipulative person — or perhaps we’ve even caught ourselves falling into that category. But do we really know when this tendency to control or influence others becomes harmful? And more importantly, how can we deal with manipulative people?

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.

The moment we distort a person’s intention, statement, gesture or action for our own personal gain we are using, consciously or unconsciously, the straw man argument − a frequent fallacy.

“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.”

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.

Almost a century ago, writer Virginia Woolf noticed people’s tendency to approach books “with clouded and divided minds, asking fiction to be true, poetry to be false, biographies to be flattering and history to chime with prejudices.”

The ability to imagine alternatives to events that have already occurred distinguishes humans from other creatures and machines—artificial intelligence has not yet succeeded in creating a device that can devise counterfactual scenarios. The fact that we can travel in an imaginary time and rewrite our actions and their outcomes can prove to be an advantage or can lead to dysfunctional emotional and cognitive...

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