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.
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.
The false cause fallacy: Is dawn summoned by the rooster’s song?
From an early age I learned, from the advice of adults or from my own experiences—and sometimes the hard way—the relationship between cause and effect. It's simple: if you touch the hot oven door, you’ll get burned! Subsequently, I discovered that there are a multitude of pressing uncertainties all around us in daily life. To figure out what actually causes the things that...
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.
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.
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.
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.
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.
Two false oppositions: reason vs. faith and science vs. religion
"Intelligent, scientifically trained people no longer believe (or can no longer believe) in God."
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.
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.
Hasty generalisations: Jumping from one to all, and from once to always
We use our experience and knowledge to understand what is unknown or inaccessible to us. We are attracted to patterns and judge the world in terms of what is already familiar to us. However, out of a desire to understand some things more quickly, we often draw conclusions without sufficient evidence. Thus we fall into the trap of the sophism called hasty generalization.
The appeal to tradition or the risk of repeating history
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.
How to critically evaluate a text
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.”
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)
