Controversy and Critical Analysis of Claims
Skeptics have classed Oscar's alleged abilities as pseudoscientific. It has been noted that Dr. Dosa may have fallen victim to Hyman's categorical imperative, that is to say, attempting to explain a phenomenon which may not actually exist. No experimental evidence has proven that Oscar has any sort of psychic ability. The bulk of the evidence provided by Dosa, such as case studies where Oscar lay with dying patients, is heavily testimonial.
Oscar's abilities were discovered by a supervising nurse who described herself as someone who wanted people to believe Oscar had powers and who subjectively searches for supporting evidence.
Dosa's works appear to suffer from biased selection; his book about Oscar fails to mention any instances of Oscar being wrong, despite the fact that the same testimonial evidence that supports Oscar's ability suggests that he has been wrong before. For example, there are stories of nurses bringing Oscar into the rooms of dying patients and forcing him onto their beds, despite Oscar's protests.
Dosa's case also appears to benefit from recognizable logical fallacies. It has been noted that much of the supporting testimonial evidence has been manipulated to create a reader-friendly story, while the opposing evidence is often ignored; this suggests the logical fallacy of enumerating favourable circumstances. He also uses the appeal to authority, stating that "experts" have discussed this and arrived at the conclusion that it was an ability of Oscar's, as well as post hoc ergo propter hoc: even if it were true that Oscar was in the beds with the patients before they died, there are third variables that could explain his behavior equally well.

“And therefore, as when there is a controversy in an account, the parties must by their own accord, set up for right Reason, the Reason of some Arbitrator, or Judge, to whose sentence, they will both stand, or their controversy must either come to blows, or be undecided, for want of a right Reason constituted by Nature; so is it also in all debates of what kind soever.”
