A psychiatrist with 20 years of experience has examined the case of Jason Arday, who resigned from a professorial position at Cambridge University amid an investigation into his qualifications. The psychiatrist, Dr. Max Pemberton, suggests that a condition known as pseudologia fantastica could offer a framework for understanding why individuals might fabricate elaborate life stories.

Dr. Pemberton notes that Arday's claims, which reportedly included invented academic posts, a fabricated childhood, and unverified feats of endurance, are highly specific and invite scrutiny. He questions the motivation behind such claims, particularly when they are so easily disproven. The gain from such lies, he suggests, is often a byproduct rather than the primary objective, distinguishing it from the more straightforward embellishment of qualifications for a specific job.

Pseudologia fantastica, a term coined in the 1890s, describes individuals whose lies are elaborate, sustained, and centered around a fantasized version of themselves, rather than for obvious material gain. According to Dr. Pemberton, those who exhibit this pattern are often not cold or calculating but rather charming and fragile underneath. The lies, he posits, are often told to the teller's ego, with listeners serving primarily to confirm the fabricated reality.

Memory itself is not a perfect recording but a reconstruction, and individuals may unconsciously alter their memories to align with their desired self-image. For those uncomfortable with their current identity, each retelling can chip away at the unwanted reality, eventually feeling like a genuine memory. These narratives often focus on overcoming immense suffering or insurmountable odds, a structure that resonates with cultural narratives of aspiration and triumph.

Dr. Pemberton draws on clinical experience, citing a case of a man who sustained a decade-long deception about being a barrister, which began with an accidental misunderstanding. This illustrates how a series of incremental lies, reinforced by positive feedback, can escalate. Neurologically, research suggests that the brain's response to guilt diminishes with repeated lying, lowering the inhibitions against maintaining a fantasy.

The extravagance of the lies can also be a factor, as the teller, like the audience, can become accustomed to previous claims. This necessitates continuous embellishment to maintain the desired level of impressiveness. Unlike a con artist who meticulously plans to avoid detection, a fantasist is not running calculations for scrutiny; their focus is on eliciting an impressed response. The risk of exposure is secondary to maintaining the constructed identity.

Dr. Pemberton concludes that while Arday must account for his actions, the institutions that promoted him, including Cambridge University and the diversity and inclusion sector, bear significant responsibility for their silence in the wake of the revelations. He suggests these institutions should reflect on their role in this situation. The article also references the film 'Catch Me If You Can' as an example of a con artist's fabricated life, with an image of Leonardo DiCaprio in the role.
