New contribution: "Theory is Two-Faced and this can be a problem for modellers" by Bruce Edmonds. #abm #theory #inference #modelling #socialsimulation #simulation #RofASSS @bruceedmonds rofasss.org/2026/10/21/theor…
Pure #SequentialSampling clusters where it shouldn't, and requires endless simulation runs. A new #ABM study shows that #MixedAdaptiveSampling can fix this, reducing costs while enhancing output interpretation.

Calibrating complex agent-based models shouldn't mean settling for a single "best guess" parameter set.
Kejian Li presents a new HPC-ABC-SMC framework that cuts #ABM calibration time by 42x while capturing complete parameter uncertainty.

Single-point estimates are not enough for complex #ABM calibration. A new framework delivers full #BayesianComputation posterior distributions with a 42-fold efficiency gain, applied to a global #FoodTrade model.

The same voting reform can polarize one democracy and moderate another. It comes down to system size.
Thomas Mustillo (@KeoughGlobalND, @KelloggInst) breaks down his new #JASSS paper on party competition under costly voting🎥youtu.be/lWkAIoc_hIE
Abstainers live at the extremes, not the centre. A new #ABM shows that voting costs reshape entire #PartySystem dynamics, driving #polarization in small party systems while eroding citizen representation in larger ones

Why is it so hard to stop eating #UltraProcessedFoods? The simple truth is that dieting alone will not do it. A new #ABM study shows that only drastically reducing UPF availability can reverse learned food preferences.

Where does inequality come from, before states, markets, or agriculture?
New #ABM reveals how stratification emerges in hunter-gatherer societies, driven by skill, luck, greed, and what a society chooses to reward.

It looks like our editor @squazzoni took some days off. Don't expect prompt replies in the next couple of days!
System-level interventions can ignite cascades of change. They can also collapse under mis-targeting.
New #JASSS paper by @gaveltri models the tradeoff and proposes a portfolio approach to scale power without losing the safety net

📢 #JASSS Issue 3 (Vol. 29) is out.
How does order, inequality, and change emerge from individual decisions? From behavioral policy to ancient societies to global trade — this issue explores it all through agent-based modeling.

🔎 Sneak peek from the forthcoming #JASSS issue:
#Nudge individuals, or reshape the systems around them? Wrong question.
@gaveltri shows it's a transformation–robustness tradeoff 👇

Who is most at risk in aged care facilities, and when?
A new #ABM study builds institutional #ContactMatrices from staff shifts and care routines, revealing where #InfectiousDisease transmission truly concentrates.

Not all nodes are equal — yet #Network models treat them as if they were. A new study adapts the Configuration Model to embed node attributes into #NetworkStructure, with a tenfold increase in #ClusteringCoefficient.

More realistic #AgentBasedModels are not always better: a new study shows that richer agent #Heterogeneity undermines #ModelCalibration reliability — reopening the KISS vs KIDS debate on new empirical ground.

No protests in the streets — yet resistance grows.
A new #ABM study models how #OnlineProtest dynamics on #SocialMedia quietly accumulate dissent potential among ordinary users even under #AuthoritarianRepression.

Bad news travels fast — but how exactly?
A new #ABM study combines #DeepLearning sentiment tracking and an epidemiological model to map how negativity about corporations spreads across Reddit's #FinancialCommunities.

What drives households to adopt rooftop #SolarPV? A new #ABM study reveals that it is not just money —#socialnorms and #opiniondynamics matter more, with surprising insensitivity to #network structure.

No algorithms, no biased media, no hostile users — yet #polarization still emerges. A new #ABM study extending Axelrod's model shows how rewarding interactions alone fuel a self-reinforcing "rich-get-richer" dynamic.
