THE CENTRAL IDEA
Change sensing concerns the relevance and credibility of information, not constant vigilance or a preference for novelty.
Concept and evidence
A change signal is useful only in relation to a task. A fluctuation in demand, a revised rule, or a repeated exception can matter; a vivid anecdote may not. The adaptive-performance literature provides a reason to examine changing conditions, but it does not establish a universal scanning habit that every person should maximize. MAP therefore proposes change sensing as an observable practice with a cost: attention directed toward monitoring is attention unavailable for execution.
The proposed distinction is between noticing, interpreting, and checking. A person can notice a complaint yet misunderstand its cause. They can also identify a real pattern but lack access to the information needed to confirm it. Questions about noticing must not silently become judgments about intelligence, commitment, or courage. An informative interpretation names the information channel and asks what a reasonable check would have looked like at the time.
Applied interpretation and an original worked example
A project team receives three urgent requests in one afternoon. One member treats them as evidence that the entire plan is obsolete. Another ignores them because similar requests have disappeared before. A third records the requests, checks whether they come from the same underlying issue, and asks the decision owner whether a priority has changed. None of these responses can be evaluated from the count of requests alone.
Our suggested exercise is to select two signals connected to a current responsibility and define a proportionate response. For example, an unresolved dependency after two agreed checkpoints might trigger a clarification conversation, while one late message would not. The respondent records both a signal that proved useful and one that was noise. This paired record prevents the exercise from becoming a retrospective success story. It also makes room for the possibility that the organization needs a clearer notification system, rather than asking one employee to monitor everything more intensely.
Studying missed changes and unnecessary alarms
Change sensing has two different error costs: overlooking a consequential development and escalating a fluctuation that does not require action. Consider a materials coordinator who checks a delivery indicator every morning. A late update might reflect an actual delay, a temporary reporting fault, or a new definition of what counts as dispatched. Counting how often the coordinator raises an alarm would confuse vigilance with accuracy. An informative record would preserve the signal available at the time, the checking action, the eventual explanation, and the disruption caused by responding or waiting.
A proposed simulation could hold the number of messages constant while varying how often a meaningful change actually occurs. The question would be whether MAP responses relate to discriminating checks, such as verifying a changed definition, rather than to indiscriminate escalation. A person might perform sensibly in a noisy environment by ignoring many messages after checking a reliable summary. Another might notice every message yet miss the one dependency that matters. We would therefore examine false alarms and missed changes separately, and ask whether any association survives when participants have equal access to the relevant information. This would test a specific interpretation of sensing, not establish a universal threshold for being adaptable.
Points to carry forward
- Use a small set of relevant signals and explicit review triggers.
- This original framework remains in development; cited research does not validate its questions.
Where the evidence stops
Signal access depends on role, information systems, and permission.
No established reliability, norms, predictive validity, or professional endorsement is claimed.
