Mastering the Art of Cross-Examining Forensic Psychologist Expert Witnesses in Criminal Defense
In criminal trials, expert witnesses — especially forensic psychologists — often hold significant sway over the jury’s perception of a case. Their testimony can make or break a defense, but effectively challenging these experts during cross-examination is a nuanced and powerful strategy. In this post, criminal defense attorney Michael Waddington reveals the tactical approach to cross-examining forensic psychologist expert witnesses, particularly in sensitive cases like sexual assault allegations, and shares insights for defense attorneys looking to strengthen their courtroom game.
Understanding the Role of Forensic Psychologist Expert Witnesses
Forensic psychologists are frequently called upon by the prosecution to provide expert testimony regarding a victim’s behavior and psychological state. Their analysis can lend credibility to the prosecution’s narrative, often interpreting certain behaviors as consistent with trauma or victimhood. Because of the weight juries place on expert testimony, defense attorneys can sometimes find themselves intimidated when facing these witnesses.
However, as Michael Waddington explains, these experts can also be vulnerable to strategic cross-examination, especially when their testimony leans heavily on subjective interpretations of victim behavior.
The Strategic Approach to Cross-Examination: Embracing the Expert’s Testimony
One of the most compelling tactics that Waddington advocates is not to outright challenge the expertise or credentials of the forensic psychologist, but rather to embrace the testimony and use it against the prosecution’s case. This involves highlighting that the behaviors the expert says are consistent with victimhood can also be indicative of other, non-criminal motivations.
For example, if the expert testifies that continued contact, such as phone calls, watching shows together, or sending gifts, is consistent with a victim of sexual assault, the defense attorney can use this same testimony to argue that those behaviors are equally consistent with a jilted lover or someone involved in a complicated personal relationship.
This strategy reframes the narrative, planting reasonable doubt in the minds of jurors by showing that the expert’s interpretation is not exclusive to victimhood but can fit multiple scenarios — including deception or manipulation.
Countering Changing Stories and Credibility
Another critical point Waddington raises is how to address inconsistencies in the alleged victim’s story. Experts may argue that changes in the victim’s account are typical signs of trauma and therefore support the credibility of sexual assault claims. The defense can counter this by questioning whether multiple changes in the story are more indicative of dishonesty or fabrication rather than trauma.
This line of questioning often involves common sense principles that judges frequently recognize as fair game during cross-examination. By framing the victim’s inconsistencies as potential lies, the defense undermines the prosecution’s case without directly attacking the expert’s qualifications.
Leveraging Courtroom Rules on Cross-Examination
Cross-examination is traditionally limited to topics raised during direct examination, but nuances exist depending on jurisdiction. Federal courts in the U.S. tend to restrict cross-examination strictly to matters discussed on direct, while many state courts — as well as courts in England, South Africa, Australia, and Canada — allow broader questioning.
This flexibility permits defense attorneys to explore alternative explanations for the expert’s testimony, broadening the scope to include questions about credibility, alternative behavioral interpretations, and potential biases.
Why This Matters: The Bigger Picture in Criminal Defense
Effective cross-examination of forensic expert witnesses is critical in criminal trials, especially when the prosecution’s case hinges on expert interpretations rather than irrefutable physical evidence. Michael Waddington’s approach embodies a deeper understanding of human psychology and courtroom dynamics, using the expert’s own words to introduce doubt and complexity where the prosecution seeks certainty.
Moreover, this method exemplifies a broader defense strategy: rather than attacking an expert head-on, the defense attorney leverages the expert’s testimony to create alternative narratives and highlight the nuances of human behavior — a tactic that can be both disarming and persuasive to juries.
