Hans Rosling – amazing!

Many of my trainees at first assume that I disapprove of visuals, because I don’t appear to use them. It’s true that there are almost never any slides in my lectures, but I have a couple of visual props that I use. Essentially my rule is that a visual should be used only if omitting it would significantly impoverish the promotion of your message. Never allow yourself to be voice-over for a string of pictures, competing with you for the audience’s attention.

The finest user of visuals that I have encountered – one of my heroes – was the late Hans Rosling. He has been on this blog twice – here and here – but not since his sad death in 2017. I chanced upon today’s offering and decided to feature it, because one of his most endearing characteristics was his cheerfulness, and we seem to need cheerfulness at the moment. My own expectation of cheerfulness is slightly dented by the realisation that Rosling outlived this performance by barely two years, notwithstanding the comment we will hear him make at 25:33.

I believe he had a superb team of techies, preparing his slides, because they always illustrated his point in a revolutionary fashion and always animated. But I have never before seen, from him or anyone else, what we see here. At 2:26 he builds a graph in the air between him and his audience. What is it: a hologram? I don’t know, but it’s brilliant.

Then suddenly we are watching some video footage, but what does the audience in the hall see? The same video on a screen there, probably, but where is Rosling while the video is playing? I don’t know, but being obsessed with a speaker’s relationship with his audience I’d like to.

Here’s my point. Many speeches are delivered to live audiences and incidentally videos are made of them. Other speeches are made specifically for the video market and an incidental audience is invited to the filming, not least to supply audience reaction. Either way it’s a bit of a compromise, because there are subtle differences in how you present to each medium. But not here. Rosling appears effortlessly to be straddling the two. My word, but he was good!

So concerned have I been with the technicalities, that I haven’t mentioned the message. If you are familiar with his work it will not surprise you to be told that he is exploding the widely held fallacies about the world and the way it is going. Materially the world – all of it! – is going not to the dogs but getting better. Nearly all metrics indicate that global life is getting better – and he illustrates the data in a hugely entertaining fashion. Watch that speech, and it’ll be one of the shortest hours you ever knew.

Yes, there are still some – a rapidly decreasing number, but some – for whom life remains a hard struggle. We see them on video, tackling their struggle with good humour, and my mind flies off to other recent video footage of spoilt kids in rich countries, rioting and burning and looting because of some imagined victimhood.

He addresses climate change – lukewarmly, but he addresses it. I reckon he has to for a lot of understandable political and financial reasons, but I’d like specifically to address a few seconds of video footage of a chimney starting at 52:20. Try going there and pausing the video.

What do you see? A factory chimney belching out filthy, sooty smoke? No. That can’t be smoke. Smoke doesn’t create itself out of nothing after an appreciable gap of a few feet above the chimney. That gap is the giveaway. What we’re seeing is steam – a colourless gas which you can’t see – coming out and cooling to vapour – which you can see. Look closely at the spout of a boiling kettle and you’ll see the same thing. Yes, the vapour from the kettle is a very different colour, but this bit of video has had a colour filter applied. It’s phoney. I’ve seen countless examples of this cheat, so I spotted it immediately.

True, there are factory chimneys with real smoke coming out of them but smoke doesn’t look dramatic enough so they cook up this piece of phoney film. I’ll say no more on that, except I’d like to think that Rosling didn’t make it but used a piece of library film that others supplied.

It’s an amazing lecture, though, and I’m so glad I found it.
