Skeptical ideas have been charged with a family of objections: they might be self-refuting, inconsistent, self-contradictory, and so on (Castagnoli 2010).
Is the tradition, then, self-inconsistent, and so self-refuting?
Nothing is denoted by the symbol '0', which in logic means "the non-existent, the impossible, the self-inconsistent, the inconceivable".
Mortensen (1984, p. 114) maintains that the condition CA ≠ ∅ "is closest to the way we think of Aristotle", and emphasizes that for a self-inconsistent proposition A, the set CA must be empty, whence AT′ is to be denied.
After removal of self-inconsistent probes among the same gene, we could identify only 4 and 6 genes (3 genes are common) in the G9a-KD and the SUV-KD cells, respectively.
Moreover, an alarmingly high prevalence (52.5%) of drug users self-reported ever having had sex with commercial sex partners, with 89.9% of these participants self-reporting inconsistent condom use in this study.
Another criticism is Plantinga's claim that evidentialism is self-referentially inconsistent for there is no evidence for evidentialism (Plantinga 1983: 60).
The main dependent variable was self-reported inconsistent condom use with any one of the four types of partners separately examined for male and female partners.
Using data from a bio-behavioural survey (2009 2010), we examined prevalence of anal intercourse, male clients' self-reported inconsistent condom use during anal intercourse with FSWs, and correlates of this behaviour in India's high HIV prevalence southern states (Andhra Pradesh, Maharashtra and Tamil Nadu combined).
The findings of these 4 studies of patient self diagnosis were inconsistent; both high false positive and high false negative rates were reported.
In Zambia a study found that couples under-reported unprotected sex when compared to STI incidence and a biomarker (presence of semen) [34], and a study in Tanzania found that self-reports were inconsistent compared to biomarkers, but that in-depth interviews were better than self-completion questionnaires [35].
