Playing with emergence is like gardening

It’s been a while since I finished reading Steven Berlin Johnson’s Emergence. I picked up the book because ever since I started thinking about what IxDs can learn from game design, the concept of emergence kept popping up.

Johnson’s book is a pleasant read, an easy-going introduction to the subject. I started and finished it over the course of a weekend. There were a few passages I marked as I went a long, and I’d like to quote them here and comment on them. In order, they are about:

  1. Principles that are required for emergence to happen
  2. How learning can be unconscious
  3. Unique skills of game players
  4. Gardening as a metaphor for using (and making) emergent systems

A cheat sheet

Let’s start with the principles.1

“If you’re building a system designed to learn from the ground level, a system where macrointelligence and adaptability derive from local knowledge, there are five fundamental principles you need to follow.”

These principles together form a useful crib sheet for designers working on social software, MMOGs, etc. I’ll summarise each of Johnson’s principles here.

“More is different.”

You need to have a sizeable amount of low-level elements interacting to get patterns emerging. Also, there is a difference between the behaviour you will observe on the microlevel, and on the macrolevel. You need to be aware of both.

“Ignorance is useful.”

The simple elements don’t have to be aware of the higher-level order. In fact, it’s best if they aren’t. Otherwise nasty feedback-loops might come into being.

“Encourage random encounters.”

You need chance happenings for the system to be able to learn and adapt.2

“Look for patterns in the signs.”

Simply put, the basic elements can have a simple vocabulary, but should be able to recognise patterns. So although you might be working with only one signal, things such as frequency and intensity should be used to make a range of meanings.

“Pay attention to your neighbours.”

There must be as much interaction between the components as possible. They should be made constantly aware of each other.

Now with these principles in mind look at systems that successfully leverage collective intelligence. Look at Flickr for instance. They are all present.

Chicken pox

I liked the following passage because it seems to offer a nice metaphor for what I think is the unique kind of learning that happens while playing. In a way, games and toys are like chicken pox.3

“[…] learning is not always contingent on consciousness. […] Most of us have developed immunity to the varicella-zoster virus—also known as chicken pox—based on our exposure to it early in childhood. The immunity is a learning process: the antibodies of our immune system learn to neutralize the antigens of the virus, and they remember those neutralization strategies for the rest of our lives. […] Those antibodies function as a “recognition system,” in Gerald Edelman’s phrase, successfully attacking the virus and storing the information about it, then recalling that information the next time the virus comes across the radar. […] the recognition unfolds purely on a cellular level: we are not aware of the varicella-zoster virus in any sense of the word, […] The body learns without consciousness, and so do cities, because learning is not just about being aware of information; it’s also about storing information and knowing where to find it. […] It’s about altering a system’s behaviour in response to those patterns in ways that make the system more successful at whatever goal it’s pursuing. The system need not be conscious to be capable of that kind of learning.”

Emphasis on the last sentence mine, by the way.

Patience

Johnson writes about his impression of children playing video games:4

“[…] they are more tolerant of being out of control, more tolerant of that exploratory phase where the rules don’t all make sense, and where few goals have been clearly defined.”

This attitude is very valuable in today’s increasingly complex world. It should be fostered and leveraged in areas besides gaming too, IMHO. This point was at the core of my Playing With Complexity talk.

Gardening

“Interacting with emergent software is already more like growing a garden than driving a car or reading a book.”5

Yet, we still tend to approach the design of systems like this from a tradition of making tools (cars) or media (books). I not only believe that the use of systems like this is like gardening, but also their creation. Perhaps they lie in each other’s extension, are part of one never-ending cycle? In any case, when designing complex systems, you need to work with it “live”. Plant some seeds, observe, prune, weed, plant some more, etc.

I am going to keep a garden (on my balcony). I’m pretty sure that will teach me more about interaction design than building cars or writing books.

Metagames as viral loops

MtG: My Pride-n-Joys by AuE on Flickr

‘Metagames’—Richard Garfield’s presentation for the 2000 Game Developers Conference—is in today’s links, but I think it deserves a bit more attention than that. Here are some quotes from the document that stood out for me.1

What a metagame is:

“My definition of metagame is broad. It is how a game interfaces with life.”

In other words, metagame design is contextual. It forces you to think about when, where, how and by who your game will be played.

Why metagame design has not been getting as much attention as game design itself:

“…the majority of a game’s metagame is probably unalterable by game designer or publisher.”

So, metagame design is a second order design problem. Designers can only indirectly influence how metagames play out. They facilitate it, but do not direct it.

Garfield divides metagames in four broad categories:

  • What you bring to a game
  • What you take away from a game
  • What happens between games
  • What happens during a game

Where “game” should be understood as a single play session of a game.

Garfield has interesting things to say about all these categories, and I recommend reading the article in full, but I’d like to zoom in on one bit mentioned under “from”:

“It is worth noting that many things listed have a ‘circular’ value to the player.”

Getting something from a game that you can bring with you again to a game makes you care more and more about the game itself. One clear example of how metagames are a helpful concept for making a game more self-sustaining.

Better yet, the ‘stuff’ that players get from a game play session can be shared or passed on to others. In this manner, the metagame becomes a viral loop.2
