The capability index is the mean of the three dimensions, each the mean of its domains, each the mean of its groups. Tiers are Pareto layers within each domain; the tier rank orders nations by domains held at Tier 1, then Tier 2, and so on. The goal-weighted score is the score sum unless the experiment sets a goal. The primary objective is the one the experiment is judged on; every other objective is reported beside it.

Credits

What each round’s credits went on in the median simulation. Across all simulations, build took 79 per cent, buy took 20 per cent, partner took 1 per cent of the 2,467 credits a simulation spent on actions.

Against history

Started from a reconstructed 1996 position and played along the pathway and shocks Italy actually had, then scored against the 2026 ratings. The position is an estimate, so part of any error is the reconstruction's. The calibration summary across all fifty nations is on the cycle's page under Loop.

The history it was played under: shocks and events

2008 · S02 × 0.8 The Lehman collapse and global credit freeze hit Italian banks, exports and small firms, triggering a deep recession.
2009 · S07 × 0.5 The L'Aquila earthquake devastated central Italy, killing more than 300 people and displacing tens of thousands.
2011 · S02 × 1.1 The euro-area sovereign debt crisis drove Italian government bond yields above 7 per cent, forcing emergency austerity and a technocratic government.
2020 · S10 × 1.3 COVID-19 made Italy the first Western epicentre, overwhelming hospitals in Lombardy and prompting a prolonged national lockdown and deep economic contraction.
2022 · S01 × 0.8 Russia's invasion of Ukraine and the resulting EU-Russia trade and energy rupture caused severe gas and electricity price shocks for Italian industry and households.

Reconstruction notes (deepseek-v4-pro): The main uncertainties concern Italy's high-technology and defence-industrial scores, where nominal participation in programmes can overstate operational capability relative to 1996 frontier leaders. Governance and public-administration scores are especially sensitive to North-South regional variation, the informal economy and the long shadow of Tangentopoli. The mapping of the 2011 sovereign debt crisis and the 2022 energy shock to the event library is approximate but captures their severe national impact.

Report

Written from the simulation record by the loop's narrator. Every figure names the query it came from, in square brackets.

Batch cycle-003. Model 0.2.0, graph 0.2.0, parameters 0.1.1. 30 simulations, seeds 1 to 30; probes on 10. Every figure is a distribution over simulations of a structural model with seed parameter values; it shows what the model implies under these settings, not what will happen. Other nations are frozen at their 2026 ratings. No reconstructed historical data is used in this experiment.

Headline

Italy played 30 rounds from 1996 under the scripted method, with scripted events, 30 times. Its capability index moved from 14.51 to a median of 13.95 (−0.55), with 90 per cent of simulations between 13.93 and 13.99 [experiment_objectives].

Starting position

In 1996 the nation ranks 16 on the index against the frozen field, holds 0 of nine domains at Tier 1 and has a tier rank of 19. Its base income is 724 credits a year, calibrated so that its 2026 position is affordable with headroom for investment.

What was decided

A simulation spent a median of 2,464 credits on moves. The five groups that took most were Communications & Digital Infrastructure (build, 215 credits, 8.7 per cent); Government Effectiveness & Public Administration (build, 196 credits, 8.0 per cent); Transport Infrastructure (build, 194 credits, 7.9 per cent); Monetary & Currency Capability (build, 185 credits, 7.5 per cent); Financial System Depth & Access (build, 185 credits, 7.5 per cent) [experiment_decisions_by_group]. By mode: build 79 per cent, buy 20 per cent, partner 1 per cent [experiment_decisions_by_group]. Concentration of spending (HHI) had a median of 0.062, and the most repeated action appeared in 27 per cent of rounds.

The leading domain by period: rounds 1 to 5, Financial Strength; rounds 6 to 10, Strategic Infrastructure; rounds 11 to 15, Strategic Infrastructure; rounds 16 to 20, Production & Innovation; rounds 21 to 25, Strategic Infrastructure; rounds 26 to 30, Strategic Infrastructure [experiment_spend_by_period].

What the world did

A median simulation saw 5 shocks and 0 upside events. The most damaging per firing were S10 (30 firings in 30 simulations, −37.0 points each); S02 (60 firings in 30 simulations, −19.5 points each); S01 (30 firings in 30 simulations, −17.0 points each) [experiment_shocks].

The groups that lost most to shocks, per simulation: Labour & Employment −3.19; Investment Attraction & Projection −3.09; Trade Facilitation & Logistics −2.99; Fiscal Capacity & Public Finance −2.77 [experiment_shock_damage_by_group].

The edges that carried most change through the graph, per simulation: Fiscal Capacity & Public Finance to Social Infrastructure (+0.61 points); Fiscal Capacity & Public Finance to Force Generation & Mobilisation (+0.41 points); Fiscal Capacity & Public Finance to Transport Infrastructure (+0.38 points) [experiment_propagation_by_edge].

Where it ended

At 2026 the median rank is 18 (5th to 95th percentile 18 to 19), the median count of Tier 1 domains 2 (2 to 3) and the median tier rank 8; the resilient score, the mean score sum over simulations, is 1,018 [experiment_objectives].

Tier 1 probability changed most in: governance and integrity (0 to 100 per cent of simulations); strategic infrastructure (0 to 100 per cent of simulations) [experiment_tiers_by_round].

Why

Without shocks the index ends +1.140 higher on average, so the shocks cost about 1.140 index points [experiment_probe_attribution].

Holding instead of following this method changes the index by −1.524: that is the method's worth against doing nothing [experiment_probe_attribution].

Removing any single one of the five largest actions changes the index by between −0.022 and +0.048, for example 2005 build Transport Infrastructure (42 credits) [experiment_probe_attribution]. The largest actions by credits come late, when income is highest, and are rarely the most valuable.

Removing the largest shock of a simulation raises the index by +0.481 on average [experiment_probe_attribution].

The replay probe reproduces the simulations exactly (index change 0.000000), so the attributions are clean [experiment_probe_attribution].

Surprises

tier_jump (warn): largest gain in one domain within five years: 6 tiers (30 simulations above 2); tiers are reported, not an objective.

retired_words (warn): e4-ita/report.md: 'simulations' 1 time(s), first near line 39; use 'simulations'.

The simulation furthest from the median (seed 7) ends +0.05 from it, with 5 shocks and 0 upside events [experiment_outlier_simulations].

Comparison

This is the baseline (hold) experiment, or there is none for this nation in the batch.

Against history: from a reconstructed index of 14.51 the model ends at 13.96, where the 2026 ratings put it at 13.72. Group scores miss by 1.78 points on average, against 1.10 for assuming nothing changed (skill −0.62); the change in each domain has the right sign in 33 per cent of domains. Furthest below history: trade and investment (−1.69); furthest above: strategic infrastructure (+1.80) [experiment_against_history]. The starting position is reconstructed, so part of the error is the reconstruction's.

What each decision and shock was worth

Counterfactual probes on the first 10 seeds: the same simulations with one thing changed, paired seed by seed. A removed decision or shock is taken out and the other decisions replayed unchanged, so the difference is that item's worth.

Settings and versions

Experiment cycle-003.e4-ita. Every simulation records the model, graph and parameter versions, the scenario, the method and its seed, so it can be reproduced exactly.

Nation: Italy (ITA)
Position: A reconstructed 1996 position, aligned to the Index's scale
Method: Scripted. Actions fixed in advance by the experiment: for a backcast, the nation's historical pathway.
Scenario: Scripted events: Global funding seizure in year 12, Core disaster in year 13, Global funding seizure in year 15, Severe pandemic in year 24, Trade bloc rupture in year 26
Objective: Capability index, the primary objective the experiment is judged on; every other objective is reported beside it
Horizon: 30 rounds, 1996 to 2026
Simulations: 30 seeds, 1 to 30. Every method in the batch faces the same draws for the same seed.
Graph elasticities: Drawn for each simulation, uniformly within each edge’s bracket
Income: Base credits 724.3 a round, moving with the economic groups
Versions: Model 0.2.0, Capability Dependency Graph 0.2.0, parameters 0.1.1
Batch: Backcast 1996-2026 (cycle-003), cycle 3 of the improvement loop
Runtime: 7.0 seconds in all; 1765 microseconds a round

Not a forecast: Every figure is a distribution over the simulations of a structural model, reported to compare methods and test the model. None is a prediction of what a nation will do or become.
Structural parameters: Costs, decay, vulnerability and credits are structural seed values with low or medium confidence, set by domain with single-group exceptions. Five groups have no defensible value in a single-nation model and are flagged in the parameter tables.
Other nations are frozen: One nation is simulated at a time. Every other nation stays at its 2026 rating, so rank and tiers are measured against a still field; where the simulated nation rises past others their own tiers are not re-sorted.
Starting depth and mode are defaults: The position is the National Capability Index ratings. How institutionalised each capability is, and how much was built, bought or partnered, have no data behind them yet and start from structural defaults.
Credits are calibrated, not measured: Each nation’s income is set so that its position is affordable with headroom that rises with its fiscal capacity. It is not yet fiscal capacity as a share of GDP.
