Bias Basics Everyone has biases when conducting an FMHA.
KNOW YOUR BIASES! MAKE THEM KNOWN! Infants should primarily be with their mother 50-50 time should be the starting point Once an alcoholic always an alcoholic Joint custody is almost always the rule

Bias Basics Bias can be positive!
KNOW YOUR BIASES! MAKE THEM KNOWN! KEEP A LOG Recent research supports infant overnights with fathers The existing schedule should be the starting point The longer an alcoholic is sober the less significance for parenting Joint custody is the rule unless a person has maltreated the child

Bias Basics Procedural Errors Methodological shortcuts that omit steps or distort results Assertion Errors Overgeneralization of research Systematic Errors Cognitive errors due to hyperfocus on an issue or hypothesis Bias is a virus in the forensic evaluator’s work.

Systemic Errors: Different Types of Bias
Expertise Bias I’m an expert in (PTSD/DV/Parent Alienation/etc) and if there’s one thing I know, this parent is (fill in the blank)! You’re Driving Me Nuts Bias If this litigant sends me one more whiny , I’ll go nuts. Therefore, the other parent is clearly the better parent. Game of Clones Bias These people remind me of the Smith case. Clearly, I should use the same recommendations
