Reading Hands and Arms in Body Language
How to Read Hands and Arms in Body Language
Hand and arm positioning is one of the biggest giveaways to someone's thoughts and emotions. For example, when someone is happy (e.g., in an interesting conversation), they will move their hands and arms in an animated manner. A happy person will even have animated arm movements when walking. Conversely, if a person is feeling down, their arm movements become more suppressed as if their arms have suddenly become heavier, and they sink, reflecting their mood.Be careful though. It is easy to misinterpret signs when reading body language, especially hands and arms.

Mimes, Partial mimes, Eloquence and Cultural Influence
Hand movements are also used to mime or partially mime the words being said (called self-mirroring), and care must be taken not to confuse these mimes with body-language cues. For example, if a person is talking about pushing a car, they might imitate the push with their palms down. That's not a palms-down gesture (covered below). It's just a mime. Similarly, if a person is talking about opening a magazine, they might rotate one of their hands from palm down to palm up. Again, that's not a body-language cue. It's a mime, or, in this case, a partial mime. Presenting mimes and partial mimes is the main reason people consciously move their arms and hands when speaking. However, the way in which the mimes are performed (e.g., in an animated or sluggish manner) can offer a clue about their thoughts and emotions. The mimes themselves don't. Eliminating them from your "reading" takes real practice. There is also a cultural influence to consider. The Mediterranean peoples use far more gesticulation to accompany talking than northern Europeans. (Picture the Italian gesticulating wildly at the scene of an accident.) It has also been observed that people who have a limited vocabulary use their hands and arms far more than eloquent individuals as a way of compensating. So, you could be dealing with an inarticulate person as opposed to a happy or an angry one. These are all factors that could confuse your interpretation of someone's hand and arm movements. And, as ever, never forget that you are looking for clusters of cues, not just isolated ones.
Arm movements also become less pronounced in those trying to avoid detection. In Iraq during the hostilities, one of the tells for spotting a suicide bomber was that the bomber exhibited far less arm movement than those around them. This is because the bomber subconsciously thinks that by not moving their body as much, they are making themself less noticeable. (It's a microcosm of the freeze response.) Similarly, a shoplifter will often have non-animated arms as they try to make themself inconspicuous. Also, an individual caught in a lie will momentarily stop their arm movements as they try to steer around that part of the conversation.
Palm Positions
Numerous experimental studies show that palms-up behaviours portray positivity, whereas palms-down ones can portray negativity or, more often than not, neutrality. Palms-up movements are also presented as a sign of honesty and welcoming. This is a well-reported trait, and anyone worth their salt who is trying to convince you of their idea or sell you something will do so with lots of palms-up gestures. You might not know you're reading their body language, but you will be.
Joe Navarro, an ex-FBI interrogator, in his book What Every Body is Saying actually shows that palm-down displays are often associated with truthful declarations, e.g. "I did not rob that bank". If the accused believes they have nothing to hide and the truth will stand on its own merits, they might not feel the need to throw in some "convincing" palms-up gestures. So, palms-up gestures only really tell you that the person wants to be believed and not that they're telling the truth. It also doesn't mean they're telling a lie. So, life's not simple unfortunately. But, all of these ideas add to the mix that you are trying to interpret.
If you are negotiating to buy a car and the salesman is exhibiting palms-up behaviour while stating that they cannot go any lower on the price, they want you to believe them, and think they are exhibiting open and honest behaviour. If their palms are down (for example, resting or pressing on a desk), their statement is likely to be more emphatic in its delivery. In the first instance, keep negotiating, because you might be able to push the price down further. In the second, they're probably at their limit, and you won't get further concessions from them. So, if you can get them from flailing around the showroom floor with lots of palms-up gestures to crying at their desk with their hands flat on its surface, you should probably take that as a sign you've won the negotiation. Clearly, it won't be as obvious as that. It's for you to read the shades between those two positions to understand how you're faring.
There's also a widely held theory out there that people who don't gesticulate with their hands when talking are considered less trustworthy than those who do. Politicians know this only too well, and they tend to be more animated than most. In particular, they like to use lots of open-arm gestures to convey honesty. They also tend to avoid pointing, which is seen as rude, opting instead for straight-hand or thumb indicating to produce a more authoritative yet less rude point.
Handshakes
Staying on the theme of being rude, next we'll look at handshakes. This is a well-worn subject, and much has been written about handshakes and how to perform the perfect shake. My advice would be not to expend too many mental calories thinking about this. Just shake the person's hand naturally and smile a bit. Your grip should be firmish, but it should not maim the recipient. Any actions that are too contrived (e.g., staring, hand crushing, being too happy, being too enthusiastic) will just be disturbing.
If you're a hand-crusher, my advice would be to quit it. It leaves a negative rather than positive impression. Conversely, the dead-fish handshake (limp and cold) should also be avoided. However, if you do encounter a limp handshake, just remember there could be a good explanation for it. The shaker might have a hand injury, be a musician or simply be a tradesman who needs their hands.
Cultural Differences in Body Language

Steepling with Your Hands

I once worked with a woman who was a senior manager. She had a tell of stroking her eyebrow whenever she was unhappy or concerned. She did it unconsciously as a pacifying manoeuvre. Beware though. Neck-touching can also be a flirt designed to encourage the target's eyes to the neck and further down the décolleté. This type of touch looks more like a downward caress rather than a straight touch, so you should be able to spot the difference. Both men and woman do it. This, in turn, should not be confused with a woman hiding her cleavage from letches. Oh, it's a minefield.
