Syllogism-Finder
This web tool helps you finding the correct syllogism name for any combination of premisses and conclusion – or at least it will show you the formal fallacies which the chosen combination would commit.

Other potential errors and fallacies
In addition to the formal fallacies pointed out by the app, other errors in thinking and reasoning can influence the conclusions. The most important problems to be aware of are listed here:
Note: The English version is still under construction! Many of the articles linked here either don’t exist yet (red links), or are still incomplete. They will be added as soon as possible.
Both premises as well as the conclusion, must be valid categorical statements , or must be in a form that can be reformulated into those.
In particular statements of the form “X are Y ” (also known as “general generalisations”) are ambiguous and do not fulfil this requirement!
To draw a true conclusion, the premises must be unquestionably true . One should make sure that: :
Ambiguities can appear in the premises as well as in the conclusion; they arise, among other things, through:
Equivocation – i.e. a term is used in multiple different meanings.Syntactic ambiguities , i.e. ambiguities in the way a statement is formed.Not to forget: ambiguities that arise from the intensions of a term or statement.
In many cases, such ambiguities are particularly difficult to detect when dealing with abstract terms, or when the specific meanings (and possibly secondary meanings) are rather vaguely defined.
In particular, misinterpretations of the conclusion should be avoided: :
As a matter of principle, conclusions must be interpreted as narrowly as possible. Except from what is expressly stated, nothing else can be concluded – except by further valid inferrences.
An existential proposition in the conclusion only states that at least one example exists. It does not imply any information on prevalence .
Since universal quantifications may have an empty extension , having one of the in the conclusion does not automatically imply that the phenomenon described actually exists.
This list does not claim to be exhaustive – there are other fallacies, such as those of rhetoric or mathematics , up to and including psychological effects by which false conclusions can be drawn.
