Critical thinking

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.

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.

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.

We live in a polarised world where conspiracy theories proliferate, but some people are more inclined than others to consume and propagate these theories rather than ignore or demystify them.

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.

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.

Do your best to present yourself to God as one approved, […] who correctly handles the word of truth. (2 Timothy 2:15)

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...

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?

No one has ever seen a thought, not even a neurosurgeon. However, today we know more about the way we think than what we were able to visualise, yet still less than we would like to know.

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

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.

“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.”

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.
