Avoid Sunk-Cost Bias in Research Segments
Review an underperforming segment using future effort, current evidence and reopening conditions rather than treating past research as a reason to continue.

The team has spent weeks researching a segment and found repeated service mismatches. Someone argues that stopping would waste all the work already done. Past effort may explain why the team cares, but it does not establish that the next hour is worth spending in the same direction.
Review the segment from the next decision forward. Separate costs already incurred, remaining obligations and the additional work required to learn something useful. Preserve reusable findings without treating them as a reason to continue a plan whose core assumptions no longer fit.
State the original hypothesis and current evidence
Write what the segment was expected to offer and which observations support or contradict that expectation. Avoid describing the whole market as poor merely because a particular service does not fit. The mismatch may belong to scope, geography, delivery capacity or the research method.
W3C's provenance overview concerns evidence origins. Link the findings to their sources and dates. The continue-pause-stop record below is an original planning tool, not a psychological diagnosis or a prediction of commercial performance.
Separate a genuine evidence gap from a confirmed exclusion. A missing answer may justify another bounded investigation; repeated evidence that buyers require an unavailable capability may justify a different decision.
A fictional forward-looking decision record
A provider has spent twelve research hours exploring a segment for on-site onboarding support. It finds that several relevant buyers require weekend delivery, which the current service does not provide. All details and durations are illustrative.
Work already completed: twelve hours of research and a source-linked set of coverage findings. Those hours cannot be recovered by continuing.
Current constraint: weekend delivery is outside the confirmed service boundary. The business has not approved a capability change.
Proposed next increment: six more hours building account profiles in the same segment. Decision value: weak unless the work can identify a genuinely different requirement pattern.
Alternative increment: four hours assessing a separate segment whose published operating context appears compatible, with the hypothesis still unconfirmed.
Remaining obligations: finish any already agreed internal handoff and follow the appropriate data-purpose and retention process. Stopping research does not cancel contractual responsibilities.
Decision: pause broad expansion of the original segment. Permit one narrowly defined check only if it could identify a service-compatible subgroup; otherwise redirect the next research increment.
The record does not claim the alternative segment will succeed. It shows why the past twelve hours should not automatically command the next six.
Preserve useful learning without defending the old plan
Retain the service-exclusion evidence and the conditions that would justify reconsideration. The work can improve future qualification even when it does not produce an active list. Avoid rewriting the original hypothesis after the fact to make every finding look like success.
A smaller viable subgroup may exist, but it needs evidence. Do not relabel the segment and continue unchanged merely to avoid recording a pause. Likewise, do not discard all findings because the original commercial expectation was not supported.
Decide what could reopen the segment
Use concrete triggers: the provider adds an approved delivery capability, buyer requirements change or a new source reveals a distinct compatible subgroup. More elapsed time or discomfort with the original effort is not new evidence.
Give a paused segment an owner and review condition, not an automatic sequence of repeated prospect contacts. Preserve relevant communication preferences and avoid treating a strategic restart as permission to recontact everyone in the old list.
Compare future options on the same basis
For continue, pause and stop, state the next effort, unresolved question and consequence of being wrong. Consider the opportunity cost of using scarce researchers here instead of on a confirmed need. Do not invent future revenue to make one option win.
The decision is complete when the team can explain why the next increment of work is justified, or why it is not. Past research remains part of the learning record. It should not become a debt that the future must repay through more activity in an unsuitable segment.
