Critical thinking

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?

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.

"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)

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.

“Yeah, I understand what you’re saying about Christianity. I’ve been there, a long time ago, but now that I’ve moved on, I have a different relationship with the universe and things are going much better for me on all levels.”

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.

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.

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

The false dilemma fallacy presents an issue as if there are only two ways to solve it—often, two opposite ways—when, in fact, there are more ways than that. The conflict between the two ways presented is also false.

A few years ago, the American Statistical Association carried out research on the history of statistics, tracing their use throughout the course of human society’s development. The results of the study are displayed in the form of a chart called the Timeline of statistics, available on the association's website.

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.

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.

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.”

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.

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.
