What’s the point of your presentation part two

Again: no I don’t think your presentations are pointless. This time I want to think about why we give presentations in the first place.

Consider conferences. From the point of view of information transfer, conferences are spectacularly inefficient, as you can usually only attend a fraction of the talks that are offered. Conferences have ecologic footprints that are just embarrassing, as attendees have to travel for hundreds or sometimes thousands of miles to get there (the mind boggles at the thought of the amount of airmiles that the average IEEE conference yields). And finally, attendees often suffer from hangovers disguised as jetlags for days after the conference.

So why do we still go to conferences (and don’t tell me it’s to feed that hangover), when in this day and age it would be much more efficient to have an electronic equivalent. It must be possible to organise an online conference that people can attend without leaving their office. The talks you were unable to attend could be recorded and attended “asynchronously” later on. Think of the money and the planet we’d save!

Why don’t we?

It’s because of lunch. Conference lunches are important. This is where people get to mix and meet and network. Sometimes people are expected to move to a different seat in between courses in order to meet more people.

It’s also because of impact. A real live speaker has much more impact than his recorded self. Also he can react to what happens, adapt his talk to help the people in his audience understand the difficult bits and answer questions. And he won’t react when you hit the pause button, so you will have to pay close attention.

And it’s because of the networking possibilities. Scientists don’t attend conferences to absorb as much information as they can. They attend conferences to find out what is new and exciting in their field, investigate (and create) opportunities for research and collaboration, meet colleagues, things like that.

This means that the purpose of your conference talk, apart from informing your audience about what’s new and exciting about your research, is to facilitate the Q&A session that follows it. Maybe the quality of your conference talk can be measured by the number of hands still in the air when the Q&A session is over. And that’s something that you just won’t see during an online conference.

Nor will you see the wine that is usually served at lunch during conferences in France and Belgium.
