The psychology behind Trump’s awkward handshake … and how to beat him at his own game

Geoff Beattie, Edge Hill University

Handshakes are meant to be relatively simple affairs, at least in terms of their signalling function. “Shake hands on it,” we are told. “Shake and make up.” They have been used as a civilised greeting for at least 2,500 years. But Donald Trump is now in the process of redefining the handshake, transforming it into the opening salvo in a battle for supremacy.

Handshakes date back at least as far as Ancient Greece – and there are artefacts from that period featuring images of Herakles shaking hands with Athena. Glenys Davies writing in the American Journal of Archaeology said that this particular scene “represents the acceptance of Herakles as an equal by the Gods”.

On other artefacts we find images of Hera, the goddess of women and marriage in Greek mythology, shaking hands with Athena, the goddess of wisdom, craft and war. These handshakes are symmetrical and equal in their execution. The sort of handshake that we would recognise instantly today.

Our common understanding is that the handshake originated as a gesture of peace, demonstrating that the hands are free and not holding a weapon. It is meant to signal cooperation, reflected in the symmetrical nature of the shape of the hands and the movement, not aggressive competition. But tell that to Trump, who uses handshakes as a weapon in his games of one-upmanship.

Indeed, Trump’s handshakes are not acts of peace, solidarity and goodwill, they are something altogether different. His “clasp and yank” handshake has taken many of its recipients by surprise. He pulls them forwards into his personal space, unbalancing them, and putting them at an immediate disadvantage. He knows that images of these greetings will be shown around the world – and that they will make it look as if he is the man in charge.

So potent is his technique that one martial arts school has even come up with advice on how to defend it.

Shaking things up

Consider, for example, Trump’s now infamous handshake with Shinzo Abe, the prime minister of Japan. Trump first presents his hand to Abe palm up, inviting Abe to take the dominant position with his hand on top. But Trump then clasps his counterpart’s hand for a 19-second marathon handshake, patting the back of Abe’s hand in several bursts of three pats. Hand patting like this is not a “comforting gesture” as some might assume. Hand patting, like shoulder touching or back patting, is a dominance signal, asymmetric in its application. Our boss can pat us on the back, we cannot pat them in return. Patting is not marked by the sorts of symmetry that constitute a cooperative handshake.

By the end, Trump’s handshake had completely overturned the initial, submissive gesture, and very much made Abe look like the (rather surprised) junior partner. But then Trump is a reality television star – he knows something about the power of iconic images and how moments such as this are perceived by the public.

In a more polite forum, a handshake should be firm, but not too vigorous, and should involve around three shakes of the hand with a full grip. It should be accompanied by a natural smile that fades slowly and an appropriate verbal greeting with the position of the handshake in the mid-zone between the two individuals.

We do know that people make judgements about others on the basis of their handshake. Research conducted by William Chaplin and colleagues from the University of Alabama, for example, showed that the characteristics of a handshake can provide accurate information about aspects of an individual’s personality.

Chaplin reported that handshakes that were “stronger, more vigorous, longer in duration and associated with more eye contact” tended to show that the individual was more extrovert and outgoing, more open to new experiences and less neurotic and shy. Similarly, in my book Get the Edge: How Simple Changes Will Transform Your Life, I discuss how this briefest of ritualised human contacts can reveal aspects of underlying personality.

Those who are particularly concerned about sending out the right signals when they meet people for the first time do think carefully about how to execute their handshake. It is reported, for example, that John F. Kennedy thought that handshakes were so important that he commissioned a study to determine the most effective varieties to use when greeting other world leaders.


Some politicians, however, are already giving Trump a run for his money, revealing how the president’s infamous handshake can be disarmed. It certainly looks like Canadian prime minister Justin Trudeau prepared himself for handshake war – and we can all learn lessons from how he took Trump on. When they shook hands, Trudeau took hold of Trump’s right shoulder to both steady himself and to stop Trump yanking him forward. And later, when Trudeau shook hands with Trump while they were both seated, Trudeau extended his fingers to signal that he wanted to be released. Together, these signal that Trudeau had at least some control over the course of the interaction. They certainly play out better than Abe’s attempts in the media clips and show that Trump doesn’t hold all the cards.

Trump seemingly believes in using any resource at his disposal to gain some advantage in the political and business worlds. Senior politicians expecting routine and formulaic handshakes have been knocked off guard by Trump’s unpredictable behaviour. They find themselves yanked into his personal space, where it is difficult or impossible for them to make eye contact, or to talk coherently without looking away. This gives Trump an advantage in the game of micro-politics.

His handshakes are clearly all about status rather than solidarity. From a psychological perspective, they are arguably self-serving and egocentric, and demonstrate that, as in many aspects of life, the most important thing to Donald Trump is Donald Trump himself.

The discomfort on Shinzo Abe’s face when his hand was finally released from Trump’s 19-second shake was plain for all to see, but Trump does not seem to care too much for the discomfort of others. If he did, he would not make them ill at ease in such a calculated way.

There’s more to life than handshakes, but they do say an awful lot about the new “leader of the free world”. And if you ever get to meet him, make sure you do your handshake homework first.

The televised political debate: Body language under the microsope

In 1960 politics changed forever.

It was the first televised political debate in the U.S. between John F. Kennedy and Richard Nixon.

The significance of the power of television in politics is demonstrated by the fact that those who listened to the debate on the radio thought that Nixon had won, whereas those who watched it on television thought that Kennedy was the clear winner.

These behaviours sent powerful signals to the television audience who made their own judgments about the suitability of each of these candidates to lead the ‘Free World’ at a critical time. And this debate revealed another great truth – once people make a judgment of this kind, it is hard to reverse that effect. Nixon did much better in subsequent television debates but it was too late. The damage was clearly done that first night.

You can see why there was so much argument and discussion in advance of the recent Leaders’ Debate itself – a great debate before the debate even started. The final compromise was a seven-person debate, with only the leader of the DUP excluded. Of course, this was going to be more unpredictable than previous formats used in the UK and brought a new set of social dynamics to bear on the process. It was going to be harder for the politicians involved to maintain their rehearsed and controlled performances in terms of their body language.

There are, after all, many behaviours that might allow the public to see behind the masks of the modern politician, like, for example, fleeting, unconscious micro-expressions revealing their underlying emotional state, be it anger, fear, disgust or contempt, where these micro expressions emerge most clearly when the masking smiles fade.

Then there is the possibility of gesture-speech mismatches when the content of the speech and the message contained in the gesture differ, but where the unconscious gesture may give some insight into the politician’s underlying thoughts. Each politician would also be trying to get their voice heard, and stand out in the debate, but there are gender differences in how politicians can do this. ‘Overlaps’ are an effective form of interruption used by individuals high in dominance and these can tell us something about the various participants in the debate.

So what did we learn that night apart from the fact that David Cameron lip licks and frowns when he is stressed, whereas Nicola Sturgeon has a very high blink rate at critical moments, indicating high levels of stress, even when her voice shows little sign of this. Or, that Ed Milliband shows lots of precision gestures to signal that he has a good grip on economic and other issues, and Nick Clegg displays lots of ‘casual’ gestures reminiscent of Tony Blair. Or that Nigel Farage displays many different facial expressions, especially when he is under attack, or that both Natalie Bennett and Leanne Wood are quite prepared to glance down at their notes, perhaps as a deliberate signal that ideas are more important in the end than appearances, as if content and style can be easily separated in this way.

Maybe, it was the higher order things that we learned, like the fact that Ed Milliband’s over-coached body language looks far too unnatural when it is extended beyond a mere soundbite, and that in real life as the topic changes, we expect to see a different set and pattern of gestures emerging, rather than the mere repetition of the same controlled set of gestures.

In other words, we want to see nonverbal behaviour that can reveal something rather than being designed and rehearsed to reveal nothing. Only his micro-expressions gave us any glimpse into his personality, character or psychological state. We also have a memory, and that Nick Clegg returning to the nonverbal style of 2010 looks like a deliberate attempt to recapture something. Or, that when it comes to interruption battles between politicians, even between politicians and the Chair, Julie Etchingham, Cameron usually comes out on top, and he often overlaps in a very dominant style. But ‘dominance’ rather than statesman-like ‘authority’ might not have been what he was hoping to signal.

But perhaps the most important thing that we learned that night was that the old two-party politics, Labour-Conservative, with attack, attack, attack the other, at any cost, may have gone forever. That was why Nicola Sturgeon appeared so effective: clever, flexible, committed, a different vision, a strong woman in a world of domineering men, body language that was more open and itself flexible, and which supported her message rather than being designed to say nothing at all, of any substance. That was why she stood out. We recognised in her body language that was believable and meaningful in a world of rehearsed control, and suppressed emotions and thoughts. And all that with a blink rate which told us something about the pressure she was really under.
