As many people lie frequently, PF [pathological lying] cannot be identified on the basis of excessive lying alone, but the qualitative nature of the pseudologue’s lies is
also quite distinct (cf. King & Ford, 1988; Weston, 1996; Wiersma, 1933). While the theme of lies can be stereotyped or varied in nature (Deutsch, 1922/1982), they are almost always dazzling or fantastical, and often develop into a complicated system of deception. The imaginative fluency of the lies tends to capture public attention, at least in the short term. The lies must keep a certain reference to reality, and though they are often unlikely, they are not beyond the realm of possibility (e.g., ‘I communicate with
aliens’) (cf. Sharrock & Cresswell, 1989; Snyder, 1986). Under close scrutiny the lies can often be easily discredited, and for this reason the lying in PF is frequently noted to be destructive to the liar (cf. Akimoto, 1997; Hardie & Reed, 1998; Healy & Healy, 1915).
