Why do small things from them hit so hard?
How hard a small input lands, set by how closely its source is tuned to you.
A response out of proportion to its cause is usually read as oversensitivity, a fault in the person who felt it. The apparatus below holds the input fixed and changes only one thing: how closely its source is tuned to you. The same small push is delivered the whole time. Move the source across the dial and watch the size of what it produces.
The push never changed. What changed was how closely the source was tuned to you. A stranger can say the exact thing and it slides off. The one person tuned to your pitch says something just as small and it swings through everything. The size of what they said was never the point. It landed that hard because it came from them.
One observation falls outside the apparatus. Subjects shown the resonance peak accepted the measurement, then asked why this person and not another sits at their center, and whether being tuned this narrowly is a fineness or a wound. The apparatus holds the natural frequency as a fixed property and measures how hard an input lands once it is set. Where that tuning came from, and whether it is a gift or an injury, is not something it can weigh. That question is reserved for future work.

abstract
A response out of proportion to its cause is commonly attributed to oversensitivity in the subject. Measurement of 327 subjects receiving inputs of fixed, low magnitude from sources of varying closeness indicates that the size of the response tracks the match between source and subject, not the magnitude of the input. An identical small input produced a response many times larger when its source was closely tuned to the subject than when it was not.
method
Each subject was exposed to inputs of fixed, low magnitude delivered by sources arranged across a measured range of closeness, operationalized as how precisely the source's manner, history, and standing were tuned to the subject. Response was measured as the magnitude of the disturbance following the input: attention captured, time to recover, and the size of the felt impact. Input magnitude was held constant across all sources, so that any variation in response could be attributed to the source rather than to the input.
results
Response magnitude was near-flat for distant sources and rose steeply as source closeness approached the subject's own resonant point. It peaked sharply for the most closely matched sources and fell away again for sources tuned past the match. The peak was narrow: the large responses belonged to a small band of near-exact matches. Across the full range the input magnitude did not vary. Only the match did.
discussion
The behavior corresponds to a driven oscillator. A periodic force of fixed amplitude produces a steady-state response whose size depends on how closely the drive frequency matches the system's natural frequency, peaking sharply at resonance when damping is light. The subject's natural frequency is a standing property that selects which sources amplify and which pass through. What presents as an overreaction is an accurate reading of how closely the source is tuned to the subject. The disproportion is a measurement of the match.
limitations
The apparatus measures how hard an input lands once the natural frequency is fixed. It treats that frequency as a given. Where the tuning came from, why a particular source sits at the subject's center, and whether so narrow a tuning is a fineness or a wound, are not quantities it can weigh. They are reserved for future work.
