> I don't really understand that use of the word orthogonal. You can imagine a two-dimensional graph with the quantity "intractable personal issues" on one axis and "chronically poor" on the other. But when the level of chronic poorness varies, sometimes the level of intractable personal issues varies as well, leading to the motion of the quantity along both axes at the same time. That is moving the measurement in one dimension sometimes results in its motion in the other dimension, so there is no way to move completely orthogonally(perpendicularly) to one axis. This is what is meant by "not completely orthogonal."
