Expert Vulnerability Report

Every opinion has a pressure point.

Paste in the opposing expert's credentials and methodology summary. In seconds, LitigationPrep maps their Daubert exposure, identifies overreaching conclusions, flags missing validation steps, and generates the cross-examination questions designed to surface those weaknesses in front of a jury.

Built on deep knowledge of forensic psychology, neuropsychology, and psychiatric expert testimony standards: the categories attorneys most frequently face in civil and criminal litigation.

What we find

The six attack vectors in forensic expert testimony.

01

Daubert / Frye Admissibility

Is the methodology testable, peer-reviewed, and generally accepted? We map every prong of the gatekeeping standard against the expert's actual methods.

02

Validity Testing Failures

Did the expert use performance validity tests and symptom validity tests? Failure to rule out malingering is one of the most damaging methodological gaps in civil and criminal cases.

03

Scope Overreach

Prognosis stated beyond what the data supports. Causation inferred where only correlation exists. Certainty language used for probabilistic findings.

04

Normative Sample Mismatch

Was the tool validated on a population that resembles this claimant? Litigation context, cultural factors, age, and education all affect standardized testing validity.

05

Credential and Role Confusion

Is the expert opining within their actual area of specialization? What does their publication and practice record actually show?

06

Literature Inconsistency

Does the expert's opinion align with published science? We surface peer-reviewed findings that contradict the expert's conclusions.
