 It is worth noting that there are at least two important processes involved in a testimonial exchange. First, there are the processes involved in the production of the speaker’s testimony, i.e., the processes that are relevant to the likelihood that the testifier speaks the truth. Second, there are the processes involved in the hearer’s consumption of the testimony, i.e., the processes involved in the hearer being able to monitor for signs that what the speaker says is false or unlikely to be true. For this reason, Testimonial Reliabilism can be developed in a number of importantly different ways. For instance, one could opt for a view according to which a hearer’s testimonial justification for believing that p is only a matter of the reliability of the processes involved in the production of the speaker’s say-so. Or, one could opt for a view according to which testimonial justification only amounts to the reliability of the processes involved in the hearer’s consumption of the speaker’s testimony. Or, one could also opt for a view according to which all of the relevant processes matter. See Graham (2000a, 2000b, 2006a), Goldberg (2010a), and Sosa (2010) for recent defenses of Testimonial Reliabilism, and see  Section 4  for additional versions of this view as well.
