Ideologues assume that there is a single version / source of the truth whether it is a religious text, or a secular one (Marx, Hayek, etc). 'Intentional moderates' are not monist (as are idealogues), but to the contrary triangulate. If anything, intentional moderates reject the notion that there is an objective position.
Accidental moderates - idealised - are actually just being reasonable and weighing different considerations, thus arriving at a considered position.
Intentional moderates may not necessarily be cowards. To take an exampe: most people are ignorant of economics and so their position on, say, the interest rate is not an informed one.
Intentional moderates use a centrist heuristic in the belief that the reasonable answer is somewhere between the two extremes. There is nothing wrong with this; one cannot expect voters to be experts or even well informed on all the posible issues of government.
