A divided, tied or scattered group: the shapes of disagreement and what to do with each one

When a group can't agree, we tend to say it's “divided,” as if disagreement had only one shape. It has several. And each one asks something different of the facilitator. Confusing them is the fastest way to force a consensus that doesn't exist, or to open a discussion the group didn't need.

I learned it by looking at results, not by reading about consensus (which is where you really learn it). In a live workshop on business models, the group had to choose which attributes of an industry (burger joints, to make it fun) we'd keep, with three votes per person. One came out with twelve votes, two with eleven, and then an eight, a seven, a five and a four. I had voted for “variety and freshness,” which seemed very important to me, and funnily enough it was one of the ones with the fewest votes; there was nothing to discuss there, the room had spoken and my vote was just one more.

But look at the shape of those numbers, because it's the first shape of disagreement: the tie at the top. Twelve, eleven and eleven isn't a divided group, it's a group that agrees there are three important things and hasn't decided which one weighs more. What's called for there isn't a deep discussion, but a finer question (“if we could only keep one of these three, which one?”) or accepting all three and moving on, which is what we did because the exercise called for five.

The second shape is scarier. It's the truly divided group: half think four and the other half think ten, and the average says seven. That's the one hiding a fight, and what's called for is to name it in front of everyone (“there are two rooms here”) and give the floor to one end and then the other before moving on. After the conversation you vote again, and comparing the two votes is the real measure of whether the conversation was worth it.

The third is dispersion (the most boring one to look at on a chart), and it's the one most often confused with the second. When the answers are scattered all over the scale, with no two clear peaks, the group isn't fighting: it doesn't have enough information, or it didn't understand the question, or the question mixes two things. Arguing there is a waste of time; what's called for is to clarify, give them the missing piece of data or split the question in two, and vote again.

There's a fourth shape that took me longer to see: the fragile agreement. Everyone votes the same, consensus is sky-high, and yet nobody is very sure. If, besides the answer, you ask how confident each person is about it, sometimes you get a unanimous group with very low confidence, which is an agreement that will fall apart in the hallway as soon as someone with authority says the opposite.

I'll grant that all this sounds very analytical for something that's deeply human. There are groups where the disagreement is about power and not information, and no chart fixes that (what fixes it, if anything, is who sits at the table). But I think telling the shapes apart helps you avoid treating every disagreement as if it were the worst kind, which is what happens when the facilitator only looks at the average: either they see consensus where there's a fight, or a fight where there's only a tie.

Today the tool I built, Kai Interact, detects this, and I say it with the bias of the person who made it. Without AI, with rules, it warns you when the group is split behind an average and when there's an agreement with low confidence, while the vote is still open, and from the same alert you can launch a second round to compare before and after. Telling a tie from a fight, on the other hand, is still the facilitator's job, looking at the shape of the votes.

Which of the four shapes shows up most in your meetings? I'd say the tie, and that we almost always treat it as if it were a fight.

See you next time. Mauro Z.
