Dyads are a way of testing hypotheses or assumptions about what makes things better and what makes things worse
They can test for the intensity of the influence of a element in a triad
Dyads are designed with two opposing negative or positive values on either end to increase ambiguity and allow the respondent to reflect on where the story sits along two polar extremes
They reveal patterns formed by plotting one Dyad as the Y-axis and another as the X-axis
Instead of using a MCQ to represent a 5-point scale (e.,g highly negative <-> highly positive), a 2D contour map axis could be a dyad allowing for a sliding scale
