Boolelauskeet

Boolelauskeet is a fictional binary connective used in discussions of logic under conditions of incomplete information. The name blends a nod to George Boole with a playful suffix to signal a skeptical or uncertain variant of a Boolean operator. It is not part of standard logic, but is used in teaching and thought experiments to explore how truth values propagate when information is partial.

Informally, boolelauskeet operates on a three-valued truth set: true, false, and indeterminate. Its behavior follows a three-valued conjunction: if both operands are true, the result is true; if the first operand is false, the result is false; if the first operand is indeterminate, the result is indeterminate unless the second operand is false, in which case the result is false. If the second operand is true and the first is indeterminate, the result is indeterminate. In many presentations it is denoted as B(a,b) or a ⊗ b, with a,b in {T,F,U}.

Origins and usage: The concept first appeared in informal writings and university teaching materials as a thought experiment to discuss how conclusions might be drawn when some premises remain uncertain. It has not been adopted as a formal standard and is mainly used to illustrate the effects of uncertainty on logical conjunction, rather than as a replacement for established three-valued logics.

Example: Boolelauskeet(T,F) = F; Boolelauskeet(T,U) = U; Boolelauskeet(U,F) = F; Boolelauskeet(U,T) = U. The construct serves as a pedagogical tool to show how different truth conditions interact under partial information.
