 With regard to this entire body of evidence, both from parapsychology and from NDEs, we may be close to an impasse. Those who support the evidential value of the experiences will argue that the naturalistic explanations that have been offered are not adequate, that they display excessive skepticism towards well-confirmed accounts, and are in many instances highly speculative. Those who reject the evidential value of these phenomena (including some believers in the afterlife) will argue that the evidence is insufficient to warrant the extraordinary claims that are made, that the naturalistic explanations work well overall, and that a full explanation of the most puzzling cases would require a detailed knowledge of the events and surrounding circumstances that in many cases is not available to us. Further careful research on individual cases may offer some hope of progress, but it seems unlikely that the fundamental disagreements can be resolved, especially when the different viewpoints are supported by diverse worldviews.
