Hoop Test
A 'hoop test' establishes necessary criteria that a causal explanation must meet to remain viable. Failing the test eliminates the explanation, while passing provides support but doesn't prove it.
When to use Hoop Test
Use this test to rule out potential causal factors that don't meet essential requirements, such as temporal sequencing (cause before effect). It helps to narrow down the list of possible explanations.
What it solves
Difficulty in eliminating implausible explanations, need for a clear and objective way to assess potential causal factors, risk of wasting time investigating dead ends.
How to run Hoop Test, step by step
- Identify the necessary criteria that a causal explanation must meet. (15 minutes)
- Gather evidence to determine whether each potential causal factor meets the criteria. (20 minutes)
- Eliminate factors that fail to meet the criteria. (10 minutes)
- Document the rationale for eliminating each factor. (5 minutes)
Materials needed
- Whiteboard or flip chart
- Markers
- Sticky notes
- Relevant documents and data
Facilitator tips
- Ensure that the necessary criteria are clearly defined and agreed upon.
- Be rigorous in applying the criteria and documenting the rationale for each decision.
- Be prepared to defend the decisions made during the hoop test.
Common pitfalls
- Defining criteria that are too weak: Failing to eliminate implausible explanations. Mitigate by using rigorous and well-defined criteria.
- Applying the criteria inconsistently: Leading to biased results. Mitigate by ensuring that the criteria are applied objectively and consistently.
Variations
- Use a scoring system to assess the extent to which each factor meets the criteria.
- Conduct a sensitivity analysis to assess the impact of different criteria on the results.
Running it online or hybrid
Use shared documents or online collaboration tools to track the criteria and the evidence for each potential cause.
What it produces
A list of potential causal factors, with a clear indication of which ones have been eliminated by failing the hoop test.
