on lying

[gusl]

While looking for something about why it's hard to maintain a consistent story when you're lying (perhaps a connection with logic), I came across:

Lying Words: Predicting Deception from Linguistic Styles

and

Iván Guzmán de Rojas -
Logical and Linguistic Problems of Social Communication with the Aymara People

Is there something special about this language that sets it apart from the many languages spoken in the Americas? The answer is yes. The first person to realize this was the Roman Jesuit Ludovico Bertonio who published a grammar and a vocabulary of the Aymara language in the early 17th century. He found that this language is remarkably fertile and articulate; that its pronunciation is unusually regular, and that it is better able than Spanish or Latin to handle abstract concepts. The learned linguist was so surprised by all this that he concluded Aymara could not be a natural language, but have been created artificially.
...
Applying methods of mathematical logic, I have attempt to determine whether Spanish and Aymara-speaking people make inferences in different ways, and, if so, to identify the differences, the areas of misunderstanding, and the maximum logical understanding that can be achieved.

and the more technical side...
THE LOGICAL SUFFIXES OF THE AYMARA LANGUAGE [from Indians in Bolivia] & Ternary Logic

It is now evident that the "Aymara siwi" has the properties of a ring. As readers well versed in mathematical logic will surely have noticed, the "Aymara siwi" differs from Boolean algebra in this respect: the algebraic operations of multiplication and addition are not identical to the logical operations of conjunction ("and"), and adjunction (alternative "or"). However, it can be mathematically demonstrated that all functions of Aymara trivalent logic can be expressed using the operators "*" and "+" of the "Aymara siwi."

all this made me think that this is a dead language, reconstructed by a logician.

Formal semanticists: how weird is this, really?
