I tentatively agree with this. But rather than approaching it from an ignorance standpoint, I prefer to think of it as beliefs caused by experience. At the end of the day experience is all you've got. Ignorance is infinite; at least experiences are positive forays into that infinity.
So, in that regard -- and at the risk of being redundant -- the beliefs you are describing, the collective beliefs of mankind whether in gods or chairs, are not different in kind, only in order of magnitude of affirming or recalcitrant experiences.
