My (stupid) fear we may, one day, become irrelevant

[Be warned: this is me in a somewhat depressive state after the deep stress I have endured by submitting too many papers at VIS’14 yesterday. I hope you will forgive me. In reality I could not be more excited about what I am doing and what WE are doing as a community. Yet, I feel the urge to share this with you. I will probably regret it in a few days :)]

I happen to click on one of the last links in one of the popular visualization blogs. I am excited. The title looks cool, the data looks cool and the design of the visualization looks super cool: sleek and clean, the way I like it. I give a look at the demo and you know what? There’s nothing there to see. Empty. No new knowledge, nothing to learn, nothing you can absorb. Nada.

This is not an isolated case. And that’s the reason why I am not happy to disclose which particular project I am talking about. First, because it would not be fair (I hate throwing shit at people). Second, because, as I said, this is not an isolated case. Third, because this particular project is only an expedient to talk about something much larger.

The way I see visualization is as a super powerful discovery tool. Stealing words to Fred Brooks, visualization for me is, ultimately, an intelligence amplification” tool: interactive user interfaces to observe the unobservable (or think the unthinkable?).

But many many visualizations out there show nothing. They are like modern food: empty calories. We, as a community, spent and still spend lots of energy debating whether one particular way of representing a given piece of information is better than another but we seem to forget that what is really important is what we decide to show in the first place. Ultimately, the yardstick should be: did you learn something watching this? Is there any kind of nutrient that enters your brain?

Let’s put it this way: if it was possible to observe exactly what kind of changes happen in the brain of a person when exposed to some new piece of information, through visualization, what would you like to see there? I would like to see a Pollock-like explosion of spreading activation followed by a difference. A delta. A sweet and tiny new brick of knowledge.

I see too much ambiguity out there. We talk about telling stories, about beautiful visualizations, and we talk a lot about wrong ways to visualize data. But what I would like to talk more is about: are we making a difference? Not a difference in the market or on twitter or whatever. A difference in people’s mind. In their brain actually.

I think the answer is mostly yes. I think … I believe … Or I like to believe. But sometime I fear we are not. The biggest fear I have, and this is the real sense of this post, is that if we will not be able to teach people how to create nutritious visualizations we may become irrelevant. Maybe it’s just a stupid thought, I don’t know, but that’s the way I feel when I get depressed by watching empty calories visualization (btw, maybe this should have been the real title of this post). The allure of pretty picture one day will end and I am not sure what will be left to see.

Creating visualizations to change people’s brain significantly is not an easy task but it’s also the only thing that really excites me about visualization  [Added note: Alberto and Gregor in the comments pointed out there is no way NOT to change your brain anyway when you are exposed to a visualization. They are right. So this is more of a colorful image than a good representation of what happens in reality. Yet, I like the concept anyway. Just don’t take to literally!]. And now that I think about it, maybe I am writing this post more for myself than for you. I want to remind myself that my ultimate goal is to help people do remarkable things with visualization. It’s so easy to forget it in the day-to-day. I want to be able to literally change those neurons and synapses and make a difference in people’s brain. That’s what counts for me. Isn’t that a more than worthy and magnificent goal?

And what is your goal by the way?

Take care,
