And here is the actual paper (linked from the article as well): https://www.pnas.org/doi/10.1073/pnas.2414274121

I remember reading somehwere about the optimal size for human groups to be efficient, but I can't recall the source. If anyone has any pointers, I'd appreciate it!

Efficient at what exactly? Doing a simple task? Complex task? Living as a self-sufficient community?
There have to be different numbers for different problems.

I think it was about the group being able to communicate effectively, to decrease conflict and coordination cost.

There was some nuance here. They blocked the abilities of the humans to communicate when achieving that result. So no talking or even gestures, only communicate like ants do.
Since we are so used to communicate when collaborating, it's unsurprising that we fail at collaborating when that is taken away.
This is a very cool study. But the conclusion is probably more nuanced.

While that is true, the paper shows more video and experiments that they did. they show that a single person finishes the puzzle way faster than a group of people. I agree it could be interesting to check how a group of people, sufficiently able to collaborate, would solve the puzzle. Would that be faster than a single person?

If it were true wouldn't all democratic societies be in danger. Our whole society is based off the wisdom of the crowds.

That seems to be university PR doing its "magic." The actual study is much more interesting: the humans weren't allowed to speak to each other, and pheromones wouldn't help the ants solve the problem, so both groups were communicating through haptic feedback. Ants do this naturally and demonstrated swarm intelligence behavior by "going with the flow", but the humans kept working at cross purposes by trying to implement a complete solution without coordinating the details.
I agree with the overall conclusion, even if it's phrased misleadingly: human collective intelligence is primarily about individual intelligences accessing group knowledge rather than groups working together to tackle complex problems beyond individual comprehension. Ants are not individually capable of understanding the piano-mover problem at a basic level; research administrators are generally capable of understanding the work of individual researchers, they just don't have the time to digest all the details.

Democracy is more or less in a permanent state of crisis. This has been discussed thoroughly since the time of Athens, and certainly Rome. The late days of the republic were characterized by squabbling over the specifics of who got to lobby voters, how they were allowed to, and where they were allowed to. For instance they have laws on the books dictating the physical structure of the buildings that people voted in to ensure that the rich couldn't basically station people in the halls leading to the ballots to purchase votes or physically intimidate voters. This is also reflected in the sudden populist turns of eg the Gracchi brothers and Caesar himself.
It's also true of the American republic. Self-conception of us as an egalitarian democracy is still around at best a century old, and more accurately around sixty years old. And we remain extremely far from being an obviously healthy democracy. Of course, the state has vacillated between actions you could argue are wise and those that are clearly not, before and after these divides.
I really would be very cautious at viewing democracies as reflecting of "wisdom". We often can (and often do) come to consensus that is extremely ill-advised from the perspective of the needs of the populace. Democracy is more or less permanently perched on the tension between the will and needs of the constituents which are often at blatant odds with each other. There's a reason why the Philosopher King has held such a cultural weight through the millennia. At best democracy is a best-faith effort to approximate wisdom through consensus—sometimes with better faith than other times.

Yup. I can't imagine that holds up today as a structural theory but the same conversation is there.

Maybe we should define democracy and state of crisis before reaching to any conclusion.
We can just as well consider human history as a graph of political crisis.
As for democracy, if we mean a system were everyone in the crowd is equal citizen and the people officially rules itself directly, there is probably no single State in the world that fits the definition.
Sociopaths have an edge to rule society as they are inclined to impose their agenda through relentless use of all the means they can think of while most people will refrain themselves from most crual actions for ethical concerns.
And of course sociopaths are going to pretend they became and remain king thanks to the will of some mighty divinity, their demiurgic actions, and their exceptional wisdom.
The appealing point for democracy is that those who have to follow the law are those who makes the law, do a feedback loop can tweak the way the society organize along the way without possibility to ignore the actual consequences of these decisions.

Given the coordination/cooperation aspect of the problem, this isn’t really the “wisdom of the crowd” as I’ve always understood it.
Something like estimating the number of beans in a jar is a good fit, since there is only one layer of perception to agree on and no coordination required.
This experiment as described seems closer to “design by committee” with (predictably) similar results.

All democratic societies are in danger -- because the wisdom of the crowd does not have the capability to handle scenarios where the crowd has sufficiently great power.
psychoslave
All political systems are in danger because the wisdom of whoever influence decisions imposed on the collectivity does not encompasses such a capability of handling actual reality in its whole complexity.
Nevertheless at the end of the day we will have political systems anyway.
vouaobrasil
An entirely meaningless response. They key is not to point out similarities, but to talk about the differences. Democracy does have its unique weaknesses, which is the drift towards efficiency over all else through capitalism, which tends to favour very dangerous and powerful technologies over time. Such a drift is simply not the case with a dictatorship or group run by elders, for example.

The lake of meaning is in our mind when we can't find any meaning to attach to what is exposed.
In that case, the text was specifically pointing to how so general statements can hardly lead to any robust conclusion.
All systems have their unique weaknesses, which can lead to dangerous situations.
On a pure retorical level, we can pick any system that can be conceptually exposed and discuss its theoretical virtues all day through. Or expose all the danger we can envision from mechanisms it implies on conceptual level.
In theory, an enlightened dictator is the best system, just as well as democracy with enlightened crowd, or gerontocracy with enlightened elders that don't fall in illusion that everything was better before and new generations are a bunch of lazy arrogant ignorants that will doom the civilization, or whatever gouvernement form we can theorize about.
It's easy to blame the ruler when you are not put with the duty to actively participate in the policy creation that should content all stake holders, and it's easy to blame the ruled ones when you don't have to obey the same rules as everyone because of course your exceptional contributions to society necessarily implies exceptional privilegies and you are the one that makes the laws anyway.
Except of course in a system where everyone is imposed the duty and means to contribute to maintain and evolve the laws that everyone have to follow, self included.

The conclusions - humans work best by themselves and the quality decreases as the number of people increases. For ants it's the opposite. Quite interesting!
