ABSTRACT
In reply to T. Tippins (2007, this issue), we take issue with his claim that recognition of the biasing impact of custody evaluators' countertransference opens the door to “evidentially legitimate” fishing expeditions through evaluators' private lives on cross-examination. We clarify the distinction between self-examination for counter-transference bias as a heuristic for improving the sensitivity and objectivity of expert testimony and its use as substantive evidence. We argue that countertransference bias is a highly personal, emotionally charged kind of bias, unlike the cognitive biases more frequently discussed in the child custody literature. We conclude that recognition of the insidious emotional influences that threaten our objectivity in working with families in high conflict divorce is an important ethical responsibility.
