What this does is measure certain foundational values of a particular culture (at a moment in time) against all other cultures. In many ways it's no different than PCA analysis in population genetics, except here we are using the outcomes of human behavior to create a behavioral mosaic.
To give an example, one evaluated metric is the Uncertainty Avoidance Index. It measures the comfort level a group of people have with uncontrolled outcomes and spontaneity. Unsurprisingly, risk avoidance is highly valued in East Asia whereas cultures in the lower left quadrant can't keep naked drunks off the soccer field. This is measured by looking at a broad spectrum of human statistics (ie. personal savings, vital statistics) and plotting them in an x/y with everybody else.

The other indices are Power Distance (PDI), Individualism (IDV), Masculinity (MAS), Long-Term Orientation (LTO) and Indulgence Versus Restraint (IVR). It's interesting to see how your own country plots, especially if you've lived in or visited several different countries with very different cultures.
There have been for a long time certain observations about societal changes demonstrated in the archaeological record, especially the time-frame when the Beakers emerge. Some of these have included the tendency towards individual burial expression (cemetery plot, megalithic or otherwise), idealistic expressions in burial, spatial distance of settlements, pioneering attitudes, cultural conformism and conservatism, etc.
The first question is a controversial question in archaeological theory. Is it possible to discern mythology, worldviews, societal structure from thin archaeological record without excessive personal bias?
If so, the second question is where would Bell Beaker culture plot within any of the matrices, say within the Power Distance Index? What is the probability that a powerful Bell Beaker chief would be attacked by a cursing mob of angry peasants? Where would that plot between Japan and Brooklyn, New York?
Was Beaker culture a culture full of materialistic, ambitious, selfish backstabbers or were they communities concerned with quality of life for all? How strictly were traditions and taboos enforced?
Where would various Neolithic, EBA, Medieval and Modern European societies plot against each other?
I really don't have time for this now, but having looked at aspects of this culture for a while, I see some similarities and some differences to the moderns. Overall, they seem more similar to modern Euros than not.
