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.
Non Sequitur: A forced conclusion is not really a conclusion
Needing to process a multitude of complex information in a short amount of time can lead to erroneous reasoning. When a conclusion is supported by weak or irrelevant arguments, the reasoning falls into the category called non sequitur—does not follow, or irrelevant argument.
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.
Erosion of trust | The ultimate effect of conspiracy theories
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.
Argumentum Ad Hominem or how you attack yourself when attacking others
In an argumentative discussion each party involved must be able to express their point of view without constraints, discrimination or other interferences. This is, in fact, an important prerequisite for the effort to overcome differences of opinion. In practice however, often things are far from this ideal. Not only do interlocutors not respect each other’s right to free speech, but they also resort...
What is critical thinking and how can one encourage the disposition to use it?
As Christians we are interested in a perpetual spiritual, moral, general human perfecting. But can we really succeed without perfecting our way of thinking, our capacity to understand, and thus without increasing our intellectual capital?
Circular arguments: a vicious cycle of faulty logic
A circular argument is an argument forming part of a thesis which has not been established, but still needs to be argued for.
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.
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.
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.
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.
Appealing to authority: an expensive logical mistake
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 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.
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 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)
