 The transactional interpretation might be seen as the most prominent—and historically significant—retrocausal model on the market, but it is not the only one. While retrocausality in quantum mechanics has been the subject of considerable analysis and critique over the years (Rietdijk 1978; Sutherland 1983, 1985, 1989; Price 1984, 2001; Hokkyo 1988, 2008; Miller 1996, 1997; Atkinson 2000; Argaman 2010; Evans 2015), the focus of this section is a review of some of the more concrete proposals for retrocausal models.
