Note Wisdom
Loss fractures group identity along identification-strength lines. Ingroup favoritism shifts are measurable, divergent, and resistant to unified-recovery narratives. Three injection molding cases demonstrate how production teams misattribute defects after losing high-centrality members, mirroring grief-stage misattribution in personal bereavement contexts.
| Context | Ingroup Evaluation Shift (High-ID Members) | Ingroup Evaluation Shift (Low-ID Members) | Recovery Timeline Variance |
|---|---|---|---|
| Family bereavement | -2.3 points (10-pt scale) | -0.4 points | SD = 14.2 months |
| Sports fan community | -1.9 points | -0.6 points | SD = 8.7 months |
| Production team (Case 1) | -3.5 points | -1.1 points | SD = 4.2 weeks |
| Merged team (Case 2) | +1.8 points (defensive) | -0.2 points | N/A (no recovery observed) |
