We welcome Mr. Korzeniewski's efforts at clarifying some of the epidemiological concepts included in our original paper. If anything, however, his critique only reinforces our fundamental point: that some courts, by applying inflexible rules of admissibility, are missing the complex and multi-disciplined dynamics underlying scientific assessments of causality. By so doing, these courts are preventing the factfinders from considering evidence that scientists would find relevant and even persuasive, thereby taking the legal system farther from rather than closer to the truth.
