Lag (noun) means: feedback arriving within the window but too late for the correction to land before the next drift. It emerges from window, drift, feedback, parameter: The interaction of feedback, drift, temporal sequencing, a persistence window, and the notion of corrective arrival upon a parameter state enables feedback to arrive too late for correction before the next drift. In the EmergenceLexicon it sits at computed level 16, chaining down to the four foundations (space, time, energy, pattern).
Examples
- In the 2012 Knight Capital trading glitch, feedback from delayed stock price updates arrived too late to prevent erroneous trades piling up in under 45 minutes. computing
- The Therac-25 radiation therapy machine administered lethal overdoses because software feedback about beam intensity arrived after the next cycle had already begun. engineering
- During the 2008 financial crisis, credit rating updates for mortgage-backed securities lagged behind actual defaults, missing the window to adjust investor behavior. economics
Emergence
through: The interaction of feedback, drift, temporal sequencing, a persistence window, and the notion of corrective arrival upon a parameter state enables feedback to arrive too late for correction before the next drift.
- untimely correction
- arrival within bounds but after need
- drift-correctable window
