Winning Discussions: argumentum ad ignorantiam (Effective Pirating)

Logical fallacies are techniques that people use to make an argument appear convincing even when it is wrong. Learning how to identify and refute logical fallacies is one of the best ways to win in a discussion. Catching an opponent committing a fallacy will force him to retract his error or he will appear foolish or manipulative to his audience. There is a dark side to this. Once you learn to identify logical fallacies you will also be able to use them. Do not deliberately use them against fellow Pirates; it is extreme bad manners and you will most probably be caught out.

The Logical Fallacy – argumentum ad ignorantiam

Argumentum ad ignorantiam translates as ‘argument from ignorance’, this fallacy is also known as the ‘appeal to ignorance’. The fallacy says that a specific claim is true, because we do not know that it’s not true. It is often used to back ideas based on religion and conspiracy theory.  Just because we do not (or cannot) know something, it does not mean any guess or theory to explain it has to be true. Often it uses absence of evidence to falsely back a claim. A negative is hard to prove and thus it lends an air of validity to such an argument. This fallacy ignores the presence of other theories (and claims) that could also explain a phenomenon.

It is often used to shit the burden of proof in an argument; the opposition being asked to prove the claim is false. For a claim to be valid there must be evidence to back it up in a positive manner.

Examples:

Consciousness is evidence for the human soul. Science and philosophy cannot explain what causes the perception of self and that we are thinking beings. However, this is not proof of a soul.

There is no evidence that the NSA is reading my emails, therefore my emails are secure.

I cannot prove it but lizard people are running the government.
(The words ‘I cannot prove it bur’ is nearly always followed by an ad ignorantiam fallacy.)

Most accusations of rape do not go to court or are found not guilty. Therefore the complainants in these cases made false accusations. There are many reasons why rape cases do not go to court or meet the high standards of legal proof. In fact very few rape allegations are malicious.

You can read more about the argumentum ad ignorantiam logical fallacy in a wikipedia post and logical fallacies in general in this wikipedia article.
Remember that just because someone commits a logical fallacy it does not mean their argument is necessarily incorrect. If you have the time and resources then use the principles of scepticism to test their reasoning objectively.

About Andrew Reitemeyer

I joined the Pirate Party of Lower Saxony in Germany in April 2012, once I found out that non citizens were welcome to join and become active members of the Party. I joined the Pirate Times soon after it was started as a proof reader and am now an editor and author. Since then I have returned to my native New Zealand and joined the Pirate Party of New Zealand. Politically I come from the libertarian left and have, up to now, not regarded any political party as having a solution for the democratic deficit that envelops the world. With the advent of the Pirate Party, which truly embraces grass roots democracy, I have found a political home. The Pirate Times is a way I can contribute to furthering the Pirate Movement around the world. Skype: frithogar
