A "chronic" liar is one who habitually tells lies, usually in a "fantastical" or "dazzling" way, with the individual telling lies often adding to past lies. For various reasons, a chronic liar cannot tell the truth.Know More
Psychologists frequently debate whether chronic, or pathological, lying is either a mental illness, an addiction, a learned behavior from the liar's environment, or a combination of several factors.
According to the PsychiatricTimes.com, Anton Delbrueck first described pathological lying in medical literature in 1891. The individual telling the "chronic lie" may or may not be aware of it, and the lie may become "extensive and very complicated." Such a pattern of lying can manifest over many years, or even over the individual's entire lifetime.
