Question 6 of 6 Advanced Scenario
When should a research program change its hypothesis or stop a workstream?
Short answer
Pivot or stop when credible repeated evidence, predefined thresholds, remaining alternatives and opportunity costs show that the current hypothesis or workstream is no longer justified.
Why
Begin with the strongest decision-relevant evidence. Have the critical assay controls passed? Has the result replicated independently?
Is a plausible alternative explanation still testable within the remaining budget? Compare outcomes against go/no-go criteria and programme priorities, while acknowledging that early discovery work is uncertain. A pivot is justified if data reject one mechanism but support a new testable hypothesis.
Stop when the evidence makes the probability of useful progress too low relative to resources and competing work, or when safety or ethics risks are unacceptable. Document options, residual uncertainties and who owns the decision. A single noisy negative screen rarely justifies abandoning a target, while repeated high-quality negative results should not be ignored because of sunk cost.
Preserve data and lessons for future programmes.
Common mistakes
- Stopping after one ambiguous assay or continuing indefinitely because a team has already invested heavily
