We’ve selected for you the most engaging news (tweets) from Australian news agencies.

How did we understand them being the most engaging? That’s simple. Those that have comments with logical fallacies of a particular kind. For example, if a comment contains Ad Hominem, we consider this tweet a bit triggering, or if it contains False Dilemma, then it’s probably a Food for Thought. You see the idea. So we prepared a couple of pieces of news for each group: “Triggering”, “Food for Thoughts” and “Team, Status Quo, and Better Life”.

Circular Reasoning also called circular logic or circulus in probando is an informal logical fallacy meaning arguer uses the same reason as the conclusion. Here is Circular Reasoning example with just rewording same statement.

Everyone must obey the law, because it’s illegal to break it.

Sometimes it forms longer chain: “A is true because B is true; B is true because A is true.” And if chain of propositions longer than that the circularity will be difficult to recognise.
