The Truth of Culture

I have been studying cultural differences and in any culture, there is always a set of beliefs everyone strongly believes in. If there is anything that is common across culture, it is this:

If only 1 person proclaim it, it is lunacy.
If 10 persons proclaim it, it is heresay.
If 1000 persons proclaim it, it is a trend.
If 10000 persons proclaim it, it is the truth.

This applies to what Americans called freedom, Singapore's 5Cs, and Chinese's harmony.

I think that when an ethnographer sees beyond these social reinforced mentality, one sees beyond morality. If there is a cross-cultural intelligence, this eye sees what the truth is.
