People have been trying to figure out other people for a long, long time.

People-patterns have existed for millennia.

For example, consider archetypes.

An archetype is a broadly accepted description of a pattern of human behaviour.

Below are examples of archetypes obtained through a simple internet search.

Interesting to note the similarities and also the grouping nuances & differences.

The question:  Do archetypes and related pattern-tools such as personas actually help marketing efforts?
