Have the russians done anything similar?
I was thinking earlier on how if we give questionnaires and suppose the truthfulness of the answers
then load the questionaries in a sheet
and perform factor analysis among types that share an increasing number of dichotomies
we should find an up/dowrising correlation trend between the factor and the number of shared dichotomies
this would indeed show at least the empirical presence of an unexplained entity which can plausibly be referred to the dichotomies
