We're obsessed with shows about con artists like Inventing Anna: the fascination lies in how easily these people can dupe us

Watching a scam artist at work

We tend to think of ourselves as good decision makers. Human brains have evolved a “cheating detecting module”, allowing us to establish cooperation with strangers. Bottom line - we assume we would see the red flags.

Watching a scam artist at work fills us with a mix of surprise at their audacity –and glee and relief that it didn’t happen to us.

But it is the methods scam artists use to con people that are the same reason we are so fascinated by them. The truth is con artists make systematic use of every rule in a veritable playbook of exploiting our human psychological foibles.

Here is how they use the rules to bypass our cheat detectors?.

Decision making is cheap and cheerful

According to psychologists, we make around 35,000 decisions a day, and each comes with an unmanageable complexity in countless options and their possible consequences.

Given our limited brainpower we automatically resort to mental shortcuts known as heuristics to make good (rather than perfect) decisions. Think of these as the software of our minds, standard operating procedures we use for all of our mundane and repetitive decisions. Examples of a heuristics we use in everyday life would be the decision of how to get to work, or what to have for breakfast, or how we evaluate people when we first meet them.

Despite their advantages in everyday decision making, heuristics sometimes get it horribly wrong.

Con artists exploit these systematically by understanding how people make good and not great decisions. Psychologist Robert Cialdini, author of Influence, the definitive manual of persuasion tricks explains the most common ones tricksters exploit.

One is the social proof heuristic - the con artist’s success and connections are meant to demonstrate that others believe them and their lies too. Here the shortcut to decision making is that we tend to rely on the decisions others make.

The Inventor is the story of Theranos, a multi-billion dollar tech company, its founder Elizabeth Holmes, the youngest self-made female billionaire, and the massive fraud that collapsed the company. IMDB

People discount the improbable

One reason we fail to detect con artists is that they are, thankfully, relatively rare, which is what makes characters like Anna Delvey and Elizabeth Holmes so fascinating. Psychologists have found that people underrate the probability of rare events. Our brains evolved economically, equipped to deal with the most important and common threats – this leaves us vulnerable to rare decision problems.

A matrix experiment on honesty, by behavioural economist Dan Ariely, revealed how much people cheat if they think no one is watching. Ariely’s experiment had participants self report correct answers, and then shred the answers. What he didn’t tell participants, is he had rigged the shredder to preserve their responses. Out of 40,000 participants, 70% lied a little – 20 people out of the 40,000 lied to the maximum amount.

What this tells us is lying a little is common, but the big cheats are rare.

People think good things come in three (or four or five)

When we meet people who present as super wealthy or super attractive, we tend to use shortcuts to attribute a whole series of positive characteristics to them.

We form impressions of one another exceptionally rapidly, perhaps as quickly as under one second after exposure to another individual.

Con artists exploit the fact seeing only one observable “good” quality in a person is enough for a favourable general impression.

We call this the halo effect, it is a confirmation bias first described by American psychologist Edward Thorndike in 1920. The halo effect explains how when we ascribe one positive attribute to someone, we inadvertently add other positive traits to our overall impression of them. So if someone is rich then we tend to believe they might also be honest, hardworking and fair.

Fame means power

Con artists often carefully curate an illusion of being famous and well connected – which Anna Delvey did with flair. We are also programmed to respond to the social status of others.

It tickles our ego if a person of perceived status engages with us – the desire for a positive self image stops us from questioning their real status of intent.

The Tinder Swindler documentary tells the story of the Israeli conman Simon Leviev (born Shimon Hayut) who used the dating application Tinder to connect with individuals who he then emotionally manipulated into financially supporting his lavish lifestyle. Netflix

It can’t happen to me

Unfortunately there is a final bias that makes us lower our guard: overconfidence. We like to think that we are not so gullible. The average person thinks they are above average when it comes to resisting persuasion and decision making.

However, the evidence suggests most people are at risk of falling for others - irrespective of intelligence and education. Psychiatrist Stephen Greenspan, author of the book Annals of Gullibility: Why We Are Duped and How to Avoid It, also fell for Bernie Madoff’s Ponzi scheme.

The one saving grace is that our interest in con artists shows our ability to learn from others’ experiences. Here the internet and Netflix are playing their part to warn us. Con artists, we are on to you.
