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 cope with manipulation
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?
The delicate burden of truth, or how to catch butterflies in a minefield
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.
I think critically, therefore I exist
We live surrounded by words—spoken with confidence, written with authority, and shared at astonishing speed. Yet behind many of them lie confusion, prejudice, and unexamined assumptions. From everyday conversations to public decisions, gaps in reasoning and expression reveal something deeper than mere slips of the tongue: they expose deficiencies in education. In such a climate, critical thinking is no luxury; it is a...
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)
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.
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.
Appeal to popularity. What explains the popularity of an error?
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.
Appeal to hypocrisy: the trick of pointing the finger
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.
How to build valid arguments
Arguments must be convincing and, in order to convince, they must be valid—the minimum requirement of persuasion.
In the world of “what if” | Why we are drawn to counterfactual thinking
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...
The anatomy of belief: Part 2 | When meaning turns into an industry
Every religious movement and "camp" is built around a desirable ideal. However, when this core value becomes an end in itself and love—the hallmark of the Christian faith—is pushed into the background, tensions turn into open conflicts.
Thinking errors: What do we do with destructive thought patterns?
What we think about ourselves, over time, becomes our reality. This is a good enough reason to identify thinking errors left running in the background and to seek out strategies for healthier thinking.
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.
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.
