The anatomy of belief: Part 1 | When reason becomes just another emotion
Western societies pride themselves on their access to information. Compared to our predecessors, we seem to be the most informed generation to have ever lived on Earth. However, paradoxically, the more data we have access to, the harder it is to determine what is true and what is false.
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.
Conspiracy theories, fake news and the truth that “sets us free”
Conspiracy theories and fake news are not the same thing, although the two categories have much in common.
The small sample and the slender majority
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.
Appeal to ignorance: Why it is useless to hide behind your finger
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.
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.
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 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.
No matter what we do, we are merely puppets on a string. True or false?
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.
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.
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...
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.
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 applications and pitfalls of critical thinking
Critical thinking is not a cure-all, but it proves very useful in dealing with, clarifying, and solving some decision-making problems, as well as the thought and belief disputes which occupy our minds.
Two false oppositions: reason vs. faith and science vs. religion
"Intelligent, scientifically trained people no longer believe (or can no longer believe) in God."
