Critical thinking

A circular argument is an argument forming part of a thesis which has not been established, but still needs to be argued for.

What we call an “irrelevant conclusion” is an argument that gives the impression of having something to do with an idea it aims to support, but which actually shifts attention to something else.

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.

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.

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.

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 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.

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

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.

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.

Arguments must be convincing and, in order to convince, they must be valid—the minimum requirement of persuasion.

The fact that we are able to anticipate most of the consequences of our actions is undoubtedly a blessing. However, we can also allow fear or over-cautiousness to make us anticipate events that are not likely to follow. This edges us toward a common error of judgement: the slippery slope.

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.

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.

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.
