Smoking Gun Test
A 'smoking gun test' provides strong evidence to support a causal explanation, weakening alternative explanations without definitively ruling them out. It's like finding a murder suspect holding a recently fired gun.
Use this test to identify causal factors that are strongly supported by the evidence. It helps to build confidence in the causal explanation and to prioritize areas for further investigation.
Solves: Difficulty in identifying strong causal factors, need for compelling evidence to support a particular explanation, risk of overlooking important causal factors.
- 1
Step 1: Identify potential causal factors that could have contributed to the outcome. (15 minutes)
- 2
Step 2: Gather evidence that would constitute a 'smoking gun' for each factor. (20 minutes)
- 3
Step 3: Assess whether the evidence meets the criteria for a 'smoking gun'. (10 minutes)
- 4
Step 4: Document the rationale for classifying each factor as having or not having 'smoking gun' evidence. (5 minutes)
- Ensure that the criteria for a 'smoking gun' are clearly defined and agreed upon.
- Be critical in assessing the evidence and avoid overinterpreting weak evidence.
- Be prepared to defend the classification of each factor.
- Use a scoring system to assess the strength of the evidence for each factor.
- Conduct a sensitivity analysis to assess the impact of different criteria on the results.
