The spin paradigm states that, to first order, it is the normalized black hole angular momentum j that determines whether or not a strong radio jet is produced (Wilson & Colbert 1995, Blandford 1999). If correct, this hypothesis has significant implications for how we should view the jets and lobes in radio sources: the jet radio and kinetic energy comes directly from the rotational energy of a (perhaps formerly) spinning black hole. Radio sources are not powered (directly) by accretion.
