BLT emphasises five dimensions or orientations for thinking. These dimensions represent material spaces and places on the BLZ model.
Left-Right: This dimension represents dyads or Zygos (i.e. pairs of related constructs) that are relevant to a problem. Tall-Short, Big-Little, Subjective-Objective, Stable-Dynamic and Active-Passive are examples of zygos. Represented by arrows <> or letters A and B.
Positive-Negative: This dimension represents different values or judgements as to how left and right are experienced. Happy-Sad, Pleasure-Pain, Calm-Angry are examples of +/- dyads. Represented by the symbols + and -.
In-Out: This dimension represents developments and differentiations (i.e. chronological and/or structural changes). Primary-Secondary-Tertiary or Past-Present-Future are examples of developments. Represented by the symbols 0 and Ꚙ.
Big-Little: This dimension represents the scope, range and context of information in focus. The Big Picture zooms out to increase the scope. The Little Picture zooms in to focus on specific details and contexts.
More-Less: This dimension represents the gradations and intensities of a value or description. It communicates frequency or intensity - 'too much - too little' - to help coordinate our approaches to problems in real-world contexts. It reminds us that thinking is always relational, gradated (i.e. by degrees) and comparative. Big is 'bigger than'. Small is 'smaller than'.
