Why we should trust our gut when giving a speech

hostile-crowdGiving a speech in public is probably one of the most nerve wracking things you can do in your life, so it’s probably fare to say that it’s something most of us would like to be better at.

I wrote a while back about some new smart glasses that aim to provide you with live feedback on things such as your cadence, volume and so on as you talk.

One thing they don’t help with is gaging the audience, but a recent study suggests that our gut instinct is actually very good at doing just that.

“When we look at a crowd of faces, what we see is not a bunch of individual faces, but rather an average of the entire crowd,” the authors say. “However, how do we know whether this average is reliable? If half the faces are happy and the other faces are angry, it would not be advantageous to see the ‘neutral’ average.”

Trusting our gut

Participants in the study were tasked with judging the emotional uniformity of a crowd of faces in an audience in under one second.

Despite the apparent impossibility of the task, it emerged that participants were actually very good at doing this, regardless of whether the crowd were happy, sad or a mixture of the two.

The authors believe that it shows how our brain is capable of rapidly processing the kind of information provided by such a crowd of people.

“Because crowds convey such important social information, it makes sense that humans are exceedingly sensitive to the average expression in crowds of faces,”¬†they say. “For example, a single fearful face tells us something about the state of that individual; a crowd full of fearful faces tells us something about the state of the world.”

Alternative cues, such as the brightness of the room or the orientation of faces in the crowd were discounted by additional experiments, all of which supported the notion that our brain is capable of rapidly interpreting facial cues on a large scale.

Scanning the audience whilst speaking is a basic heuristic you’re instructed to do. ¬†This advice is typically given to show the audience that you’re talking to them, but this study suggests it may also be a great way to take the temperature of the room.

  1. I've always found that it's best not to think too much when giving a speech. It's like riding a bike, when you start thinking about what you're doing, you tend to fall over. Do your preparation and then go off of instinct.
