Critical thinking is one of the 21st century skills required to participate in our society. A student should learn to adopt an investigative approach at all times. Do not take the information you find in source material as true without further research. Analyse and assess the quality of the source.

Changing definitions

A pure or logical reasoning follows the laws of logic

  • statements
  • observations
  • conclusions

False comparison

In texts we usually find reasonings of another type. It is not always as simple to recognise the claim and the arguments and to see from where the conclusion comes. In order to assess these kind of texts we use the five help questions: what? why? who? when? where?

Types of faulty reasoning

Generalisation

Invalid arguments or reasoning faults are quite common when trying to convince the reader, conscious or unconscious On this page, you will find a few common examples of reasoning faults.

Exchanging cause and effect

Unjustified appeal on authority

Manipulating numbers

Juggling with numbers is quite common in the media. One newspaper says that unemployment decreases by 2,5%, while another newspaper says that youth unemployment and long-term unemployment have increased by 4,4%. It depends on how you look at it and how you interpretate it. It is important to look at the big picture and look at the numbers in the right context. A few examples can be found on this page.

Hoax

A hoax is a message that presents itself as true, but is partially or completely wrong. Sometimes they are harmless jokes, but at other times the concequences can be very grave. Here you can find a few examples of a hoax.
