This is a Lexicon entry: the mechanism, when it shows up, and the countermeasure. The full correction, with real-world cases and the audit prompt, hasn't been written yet.
Definition
The tension present in every decision system between exploring new options (uncertain payoffs) and exploiting known good ones (predictable payoffs). The young, owning little, can afford exploration and norm-disruption; the old, having accumulated stability, must exploit what they have built. This tradeoff is a key mechanism behind why people become more conservative with age - not moral failure but rational portfolio management.
When it shows up
Career moves, dating, investments, product strategy. Any situation with a current-known option and unknown alternatives that might be better.
Failure mode
Over-exploration: you never commit; value is never realised. Over-exploitation: you lock in early on a local maximum; better options that would have been found go undiscovered. Neither is obviously wrong until outcomes accrue.
Countermeasure
Calibrate the mix to the time horizon. Young agents with long futures should explore more; older agents with less future should exploit more. At any age, explicitly schedule some exploration even when exploitation feels safer.
