The questionable cause fallacy: Correlation does not equal causation

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.

The false analogy: when the apple insists on being a pear

The false analogy or the faulty analogy consists of the incorrect use of the analogy argumentative scheme without first meeting the requirements of a correct comparison.

How to study the Bible properly

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

The straw man. An argument the size of a flash in the pan.

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.

Reading polls: How do we evaluate surveys carefully?

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.

The biased sample: why science should not be practised on friends

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.

How to think outside the box

"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)

Manipulation: when disinformers believe in us

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

Equivocation: Playing hide-and-seek in communication

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.

Seduced by conspiracy theories

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.

Accurate statistics and faulty interpreters

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

Thinking as self-defence

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.

How to make sure we have a rational faith

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.

Enchanting words | When deductive thinking becomes the logic of the masses

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 end of the world, overlooked by philosophy

"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)
