The reason I posted this to HN, is because I am curious as to how many people here hack at their own body language, and whether you tend to focus on "improving" it, or just let it be "natural", whatever that means. And if you are "improving" it, what are your considerations for particular situations? Do you try act as if you are from a lower SES, to try to level yourself with your listener, or the other way around - try to increase the perceived importance of your SES in order to put down your listener?
There are some good papers on perceived IQ, and how perceived IQ correlates with actual IQ. It turns out that pIQ is mostly a function of body language, eye contact, rate of speech, and things like that; what comes out of your mouth doesn't actually matter all that much. Some of the factors you are able to fake and boost your pIQ, but most you aren't. So if you are into that it would pay off well to figure out what those are. :-)
Social skills can be hacked. Remember unconscious incompetence -> conscious competence.
RE: Body Language.
Move slow, talk slow, be an approval giver (not a seeker). We all have the capacity to be at the level of Bill Clinton or other legendary communicators - we do it on first dates, job interviews - he does it all the time. One of my most networked/outgoing friends consciously goes into certain situations like 'she owns the venue'. Also if you talk to everyone, you can hide the fact that you are interested in not everyone. You might also try videotaping your body language when you are with friends/familiar situation vs strangers/safe situation. You will have to try this to realize the power of this - but if you really, really want to talk to a group or even a cute female who is seated alone/together, drag a chair over from the other side of the room (noisily if possible) and sit down with them. That demonstrates commitment and is an opener all-in-one.
RE: Peer ratings
They are a form of social proof (raters do not exist in a bubble).
"Similarly, a person who has been unemployed for a long time may have a hard time finding a new job - even if they are highly skilled and qualified. Potential employers attribute wrongly the person's lack of employment to the person rather than the situation. This causes the potential employers to search more intensively for flaws or other negative characteristics that are "congruent" with or explain the person's failure and to discount the applicant's virtues."
One of the more clever and disturbing ways to gain 'power' over an individual is to play the student in the master-student role. E.g. by having them teach you something - which is doing you a favor, you can gain their favor.
I never really paid much attention to mine: after all, I'm a nerd, judge me on what I do, not how I look. However, when I ran for office, I found that I needed to - because the vast majority of people judge solely on looks, appearance, and to a much lesser degree, actual message.
I notice it's hard to get things done in a meeting when your arms are crossed over your chest or abdomen. It's the universal sign of "I disagree with you and I'm on the defensive" Try this: cross your arms, and the person across from you will inevitably do so as well. I find that when they do that, it's much harder to convince them of your point of view. It's almost as if their defensive posture puts their mind into defensive mode. The opposite seems to hold true as well: relax your posture (open arms) and the person will be more receptive.
It's called mirroring - a psychology process in building rapport. We all do it when comfortable with a friend / family member. You can use this to your advantage to win people over to your side. Just try not to be too obvious or they might spot you! ;)
I used to believe that too (and there are dozens of books that actually say the same) - but what I've noticed for quite some time now is that this little bit of posture doesn't play that big of a role, after all. Probably because everybody has read the same best-seller 'mastering body language' books.
When facing a difficult problem and trying to project confidence, I prefer sitting astride a rearing horse, brandishing a sabre.
The body language mirroring and influence thing has a comprehensive theory on using it to your advantage: Neuro-Linguistic Programming. Unfortunately, it has little experimental support, but it's still trendy with the management and life coaches--which doesn't necessarily make it not true; which wouldn't necessarily make it not useful.
This wasn't about trying to project confidence. It was a study that looked at students working alone. I find I will sometimes cross my arms if I am thinking hard about a problem. What was interesting was that the study provided some evidence that it would help me to persevere.
