What This Means

QGI found 2,435historical cases where other countries' economic indicators followed a trajectory that subsequently led to a terrorist attack event. United Kingdom's current indicator trajectory matches these historical patterns.

This does not mean United Kingdom will experience terrorist attack. It means the economic conditions that historically preceded such events in other countries are present in United Kingdom's current data. Analysts should examine the underlying evidence and apply domain expertise.

QGI surfaces economically-grounded risk candidates that analysts should examine. Risk tiers reflect historical precedent density, not probability forecasts.
