Some anthropologists and practitioners have discussed the impact of such neoshamanism as "giving extra pay" (Harvey, 1997 and elsewhere) to indigenous American traditions, particularly as many pagan or heathen shamanic practitioners do not call themselves shamans, but instead use specific names derived from the European traditions—they work within such as "völva" or "seidkona" (seid-woman) of the sagas (see Blain 2002, Wallis 2003).
