Yep. It also correlates extremely strongly with an increasing decrease of violent crime. One of the symptoms of low level constant lead exposure is increased aggression and volatility.Â
As you may know, the word âSiouxâ is considered to be a slur amongst members of the Oceti Sakowin. It is not our word for ourselves, but rather a name given to us by another nation and perpetuated by the Europeans / Euro-Americans.
You also may have noticed that our official tribe names often contain the word âSiouxâ (âOglala Lakota Sioux Tribeâ for example.) The reason for this is entirely legal. When our treaties were drafted, they were written as an agreement between the US Government and the âSioux Nation.â For this reason, we cannot fully abandon the name. However, when weâve had opportunities, weâve dropped the name in places we can (âOglala Lakota County,â for example, a name chosen by the rezidents.)
Simply put, members of the Oceti Sakowin generally donât refer to themselves as âSiouxâ and, if we canât change it legally, at least we can continue to assert our identity on our terms. So, if you choose to respect that, hereâs a quick Oceti Sakowin education guide:
Oceti Sakowin (Seven Council Fires)Â
Oceti Sakowin (encompasses all language dialects) is the simplest and broadest replacement for âSioux.â You can use this term if you arenât aware of the specific language group to which âSiouxâ refers. Within the Oceti Sakowin are three main groups, which are further divided into seven subgroups:
(Mnikiwoju/Mniconjou) – Swamp Plant  (Cheyenne River Reservation)
Itazipcola
(Itazipco) – No Bow  (Cheyenne River Reservation)
Owohe Nunpa
(Oohenunpa)
– Two Paunch Boiler (Cheyenne River Reservation)
Sihasapa – Black Feet (Cheyenne River Reservation, Standing Rock Reservation)
Hunkpapa – End of Horn (Standing Rock Reservation)
*modern terminology
*In the past, the term Nakota has been applied to the Yankton, but this is a mistake. The Yankton speak Dakota. Nakota speakers are Assiniboine / Hohe and Stoney, who broke off from the Yankton at a time so long ago their language is now nearly unrecognizable to Lakota and Dakota speakers.
