How do evaluators mitigate contamination during exercises?

Evaluators mitigate contamination during exercises primarily by establishing clear evaluation criteria beforehand. This approach creates a structured environment in which all participants understand the parameters of the exercise, minimizing bias and confusion. Establishing clear criteria ensures that evaluators focus on specific objectives and outcomes rather than being influenced by informal conversations or previous exercises.

When criteria are clearly defined, it helps in maintaining an objective perspective during the evaluation process, allowing for a more accurate assessment of performance. This reduces the potential for preconceived notions or biases that could arise from discussions of past exercises, leading to a more reliable evaluation of the current exercise's effectiveness.

Maintaining confidentiality agreements and documenting necessary adjustments may also play roles in the overall integrity of the evaluation process, but it is the establishment of clear evaluation criteria that serves as the foundation for ensuring that evaluations are based on the trial at hand, rather than on external influences or prior experiences.
