Gardner said,
"The naturalist intelligence refers to the ability to recognize and classify plants, minerals, and animals, including rocks and grass and all variety of flora and fauna. The ability to recognize cultural artifacts like cars or sneakers may also depend on the naturalist intelligence. …(S)ome people from an early age are extremely good at recognizing and classifying artifacts. For example, we all know kids who, at 3 or 4, are better at recognizing dinosaurs than most adults."
In my perception that boils down to
the human ability to solve problems or to make something that
is valued in one or more cultures
Our naturalist intelligence allows us to focus on hierarchical categorizations, development of humanity and preservation of life on Earth.
This intelligence likes to keep pets, feels at ease with elements of nature, trees, flowers, plants, stones, animals, maintains interest in the ecological issues that seem to dominate contemporary consciousness of mankind, possesses excellent knowledge of the functions of the body, usually live healthy lives in accordance with this knowledge, and is interested in the origins of the universe and the evolution of life.
The associated roles seem highly valued in environments where power jockying is required and our ability to identify types of drivers of others quickly, by where offices are located, type of cars driven, clothes worn.
Mapped to the Sweet Medicine Wheel healing preferences, this would fit trickster healing. Trickster healers or healing uses symbols, sigils and imagery to “trick” people into healing themselves. Do not close blinds or curtains on this intelligence.
