Systemic Consensus

Cover: Systemisches KonsensierenYou know that saying “Don’t judge a book by its cover”? Well, I usually do jugde a book by its cover and I’d never have bought “Systemisches KONSENSIEREN” (“Systemic CONSENSUS”)! When a colleague dropped it on desk, I made fun of it – its whole appearance is “touchy-feely” in a bad way and, come on, CAPS? Really?

Fortunately, I picked the book up on a whim and its main (and only) idea immediately took the top position on my list of “things to try out”: When voting, don’t have the usual majority vote that generates winners and losers. Turn traditional voting upside down and determine least resistance!

Let me illustrate how that works with the first example in the book: There were 4 high-paid marketing people working on an ad campaign for a car. Everything was finished and decided, except for what color the car should have in the ad. They each strongly wanted a different color and majority vote always turned out like this:

Darkblue: 1
Silver: 1
Red: 1
Black: 1

Various attempts to agree among themselves were fruitless. Neither could they agree on whom else they might bring in to settle the matter. And the client said it was the professionals’ call. A deadlock.

Enter systemic consensus: Each of the 4 parties rates their rejection of each option on a scale from 0 (no resistance, I totally want this) to 10 (I’ll kill myself, if we take this). The result this time:

Marcia Perry Ana Jack Total Resistance
Darkblue: 0 2 4 3 9
Silver: 5 0 8 5 18
Red: 7 4 0 6 17
Black: 3 7 8 0 18

Yay, we’ve got a winner: Darkblue meets least resistance. Everyone can live with this color.

Given, in this simple case, they might have also reached a decision with an acceptance-based mechanisms finer grained than “1 vote only”. So why use “resistance” which rings negative with many people? Why not vote “acceptance” on a scale from 0 to 10?

Let me quote Diana Leafe Christian describing her first encounter with systemic consensus in something similar to a town hall meeting:

[…] I had trouble with “resistance” points. He [Ronald] helped me understand that they’re used for psychological, not mathematical reasons. If you ask people to think about why they want something, he said, they may not think about it as clearly as when you ask them why they don’t want it. If people have to ask themselves, “How much do I not want this?” — it forces them to better analyze the proposal.

The book states additional advantages as:

  • Systemic consensus shifts focus from building alliances and “winning”, to incorporating the needs of others into your own proposals
  • No one loses. The group wins.
  • It makes sense to pick the option with least resistance, because it has the highest chances of actually being implemented by the group. (With majority vote I’ve often seen the defeated parties just ignoring the ruling.)

The authors claim that systemic consensus cannot be gamed by malicious parties. Their examples didn’t quite convince me. I’d need a lazy afternoon and my game theory hat to think about it in depth. Anyway, I’m usually not among malicious people and eager to give this a shot!

Do you want to know more?

Do you have first hand experience with systemic consensus? How did it work out for you?

  1. Sound interesting, although I would have never guessed that “konsensieren” is a word 🙂

  2. Buck says:

    And this is how Wulff got to be president.

    @Buck What do you mean? If you want to imply that systemic consensus might lead to foul compromises… That’s also something I want to ponder on, with my game theory hat on. In the meantime, Wulff got to be president by majority vote. So you wouldn’t be off worse with systemic consensus than majority vote.

    • Buck says:

      So my impression was, that when a new president had to be found Wulff was a candidate that noone really opposed enough to let the rival candidate of the opposition win.

      We can probably agree that very few would have considered him the single best german citizen for that job, even at that time. Now the way you select a candidate for presidency is closely related to the above aproach to finding the most mediocre choice: You want most of your party members voting for your candidate, ideally everybody, as a defeat would weaken the governing coalition.

      You also know that your coalition members maintain a bias both towards your candidate and against sticking out by voting independently which would happen if you proposed someone who isn’t round as an egg.

  4. Buck says:

    What about the alternative vote? Not sure how this compares from a game theoretic point of view (the online course hasn’t even started) but intutively the best choices so not stick out because noboby has a strong opinion about them. The idea is basically not to aggregate binary votes but rankings.

    • Buck says:

      That came out wrong, probably due to missing punctuation. I just wanted to say that interesting choices often raise strong opinions. But that does not really count as an argument as we are looking at the mean hate/love rating not the variance. So yes, this seems to be a good system.

      One thing: Why don’t the people use the full 0-10 range in the example? It seems this limits their influence on the outcome.

    • Corinna says:

      “Alternative vote” also sounds interesting (but when I imagine it in my workplace, I foresee a hefty bit of confusion). Thanks for the link!

    Heh wow, that is very similar to a technique I developed and tried out in 2010:
