"Country X has been lucky." "Nation Y has low population density." "Climate in tropical state Z has an impact."

Probably true, but then still:
#leadership
#strategy
#trust
#communications

massively influence a country's dealing with a #pandemic or a #crisis.

1/
Would countries have done better or worse with different #leadership and #strategy? I have NO DOUBT.

Key drivers like #leadership and #trust often seem underestimated or hard to grasp.

This is probably due to #complexity of the matter and that drivers are hard to measure.

2/
The drivers are all related:

#leadership ➡️ trust ➡️ successful execution of #strategy ➡️ empowered leadership ➡️ #trust

#Communications is the glue.

Mimicking Simple Life Without Biochemistry

Follow this thread for insights from today's SFI Seminar by Juan Pérez-Mercader (SFI + @Harvard), which you can watch live on our FB page. Recording will be saved for later viewing at this link, as well as YT:

#astrobiology #biochemistry #complexity
What properties characterize life? The search for a fundamental theory of #biology continues to face some serious challenges:
• n = 1
• no unified math
• can't modify carbon experimentally
• biology is still process-description
BUT: ✨ info-metabolism-replication-evolution ✨

I recently published a @kumupowered presentation with my take on the system dynamics behind the COVID-19 crisis: kumu.kumu.io/covid-19
As expected, the first "But why doesn't it show [this factor], [that factor], or [the other factor]?" question came rolling in quickly. And those questions are welcome and encouraged!

But I answered with what I felt was a pretty good blanket response, so I'm threading it here.
There are a huge number of factors and variables that would and should be present in a high-resolution map modeling dynamics of the system and predicting outcomes at specific points in the future.

Whole lot of hot takes out there around #COVID19, foresight, and the #BlackSwan concept | Dear readers, I present to you...the hottest of hot takes: #coronavirus both "is and is not" a black swan, & this is the most reasonable, rigorous, & responsible view
But first, yes...foresight actually works! And not because it can help you "predict" the future, but precisely because it can help you understand complex phenomena and, at best, spot "emerging issues." See: &
And, the folks at @CSIS struck gold: csis.org/analysis/we-pr… Unfortunate use of the word "predict," which literally means "say before" & should be banished from the vocabulary of all futurists. Great stuff from @BryanAlexander here: bryanalexander.org/futures/antici…

Today's Applied Complexity Symposium begins with a panel on Computation and Complex Economies, feat. Rob Axtell, Joshua Epstein, @C4COMPUTATION, Blake LeBaron, John Miller, & @MelMitchell1

(Follow this thread for live coverage all day...)

#complexsystems #economics
4 Principles of Collective #Computation:

1 Ground truth (objective reality)
2 Effective ground truth (what we agree on, whether or not it is accurate)
3 #Information can be collectively encoded in #networks
4 Outputs are a product of collective dynamics

@C4COMPUTATION right now
"I think #economics really needs to adopt a generative framework with agent-based models of cognitively plausible software people...[and] we don't choose to fear."

SFI President David Krakauer introduces our annual board of trustees symposium on New #Complexity #Economics - follow this thread for live coverage of talks by @EricBeinhocker @AKStanger @ole_b_peters @JacksonmMatt @cmoncap & W. Brian Arthur today...
"I think we have to be aware that we're not just discussing financial systems. We are discussing the future of the stability of the planet."

- David Krakauer
on #Complexity #Economics
"What is the #economy? I would argue that it doesn't exist in the physical world. It is a product of our #imagination. It is made out of #ideas. It does have an effect on the physical world. But the imagined order that we have is not succeeding."

"Information theory, predictability, and the emergence of complex life"

SFI Seminar by Luis F Seoane of @IFISC_mallorca, streaming now:
"The size of the #environment in some ways captures the #complexity...longer words take longer and longer to sample. This means in smaller environments, smaller words mean more."

- Luís Seoane of @IFISC_mallorca on #information right now:

"More-complex bit guessers are going to survive in a wider variety of environments. But a more-complex guesser is going to pay a higher metabolic cost."

We create #games & #simulations at @fovlabs to improve public policy. These tools are meant to help us live with the #complexity around us. The journey to create a non-academic research space in India hasn't been easy. #payitforward (1/n)
How do you create a space that helps address the complex problems we face as a society? How do you create tools to facilitate dialogue with stakeholders? How do you build bridges? How do you grapple with diversity without paying lip-service? #payitforward (2/n)
These were just a few questions that we were interested in, what we needed was somebody to listen to us, bounce some ideas off, support us financially, and just be there for us. #payitforward (3/n)

#Complexity Theory: One of the many non-intuitive implications of this approach is that the more complex a problem, the simpler the solution must be. Unintended consequences & butterfly effects render complicated solutions unworkable within a few steps 1/n
The conventional approach is that India is a complex country that requires complex solutions. Complexity theory implies exactly the opposite. Only simple policies, frameworks and institutions can function in India. Leave complex solutions to Singapore 2/n
Another implication of Complexity theory is the 80:20 rule (or some version of it). A 20% solution will often solve 80% of the problem. In many situations, one should leave it at that as further interventions will have unintended consequences & render the system unworkable 3/n

1) Antifragile on health of bones: bones are part of the endocrine system, not some engineering structure.

You don't improve your bone with exercise machine.

@Mangan150 attributes the fertility crisis to correlative (Om 6), not causative (osteopenia)

#Complexity
#ICCS2018
2) The bone also regulates memory and mental functions via osteocalcin (Karsenty).

SPECULATION: can healthier bones for overweight pple explain the all-cause-mortality effect?

POLICY: just follow the phenomenology that healthy pplw have healthy bones and ignore mechanisms?
3) We know that osteocalcin restores muscle endurance. Muscles strength are less investigated.

Again fughedabout mechanisms, take phenomenology: @CoachRippetoe reports that only heavy weight bearing exercises you do standing up count.

[Thread: let's talk the #ThaiCaveResue, intervention research, and #complexity]

Struck by how Musk's mini submarine - “made of rocket parts and named Wild Boar after kids’ soccer team”- is a teachable moment for intervention research in #complex settings

Let's take a look at why, using complexity theory.

Musk's rocket is indeed highly sophisticated and built through 'rocket science', yet on-site it has been deemed ill-suited for this complex rescue mission

How is this so and what can we learn from it?
First: good graphics here of what this labyrinth cave complex looks like, and what the rescue entails (or, at the very least, the *known* problems the rescue mission is likely to encounter)
