The strategic value of a psychological expert, Lucas A. Klein, Ph.D.
In civil litigation, the strength of your client’s case often depends not solely on legal doctrine or documentary evidence, but on how a human being thinks, feels, remembers, and behaves—especially in cases involving mental-injury claims, emotional distress, capacity issues, fitness for duty, or other psychological dimensions. That’s where engaging a qualified forensic psychologist can become critical.
As a licensed psychologist in Idaho (and additionally in California, Oregon, New York and Connecticut), I consult with law firms of all sizes across those jurisdictions. I consult attorneys in all 50 states and can provide evaluations in any state depending on statutes and license agreements. I also offer a free consultation to help determine whether the facts of your case are a good fit for psychological expert work.
Why partner with a psychologist expert?
Here are key benefits:
Credible measurement and evaluation
A psychologist brings validated assessment tools, interview protocols, record review, and clinical judgment. Whether it’s a claim of emotional distress, traumatic brain injury, post-traumatic stress, or cognitive impairment, the expert can provide structured, reproducible, peer-accepted data rather than mere anecdote.Conversion of clinical findings into litigation language
The psychologist translates complex psychological and neuro-cognitive phenomena into expert testimony, reports, and depositions that a jury, opposing counsel, or judge can understand. This strengthens your ability to explain “why” a person behaves or reports the way they do.Anticipation of opposing expert arguments
Just as you anticipate opposing legal counsel, you can anticipate opposing-expert strategies. A retained psychologist can help you foresee defense expert arguments (malingering, lack of causation, alternative explanations), and craft your theory accordingly.Development of persuasive expert report and testimony
Excellent expert-witness work isn’t just about ticking the boxes. It must be logically structured, well-reasoned, tied to evidence, and clearly articulated. The psychologist expert can craft a report that supports your client’s position and presents well under cross‐examination.Impartiality and credibility
A retained psychologist whose professional reputation is strong and who follows ethical standards adds credibility. In complex civil cases (employment disputes, personal injury, catastrophic loss, historic abuse), jurors and judges expect the expert to have depth, impartiality, and transparent methodology.

I am licensed as a psychologist in Idaho, meaning I can conduct evaluations, write reports, serve as an expert witness, and testify in Idaho courts.
I am also licensed in California, Oregon, New York and Connecticut, which means I consult with and serve law firms of every size in those states for a wide variety of civil litigation needs.
I provide a free consultation to help determine whether your case is a good fit for psychological expert services — you and your client can assess scope, cost, timeline and strategy before committing.

Typical scenarios in which I partner with attorneys
A plaintiff claims emotional distress after a traumatic event, and you need an expert to assess and testify to causation, severity, prognosis, and linkage to the event.
A defendant contests the severity of claimed psychological injury—or alleges pre-existing or alternative causes—and you need robust counter-analysis and expert rebuttal.
An employment-law matter where a key executive’s mental fitness or alleged conflict-related stress is at issue.
A personal-injury matter with neurocognitive symptoms
A class-action or mass-tort scenario where psychological and behavioral data lend legitimacy to aggregate or individual impacts.
Tips for attorneys when engaging a psychologist expert
Engage the expert early. The sooner the psychological dimension is mapped out, the better you can integrate that with your legal theory.
Provide the expert with rich records (medical, psychological, employment, academic) and a clear brief about how you expect the psychological evidence to support your case.
Ask about methodology upfront: Which tests, clinical interviews, record reviews, collateral contacts will be used? What is the timeline and draft‐report plan?
Clarify cost structure and deliverables: Will the expert prepare a written report, be available for deposition, attend trial, review opposing expert’s work? I can help you determine the answers to these questions.
Use the free consultation to assess strategy and fit: Not every case is well‐suited for full‐scale expert psychological assessment, and sometimes a lighter consult or file review may suffice.
Final word
In civil litigation, the psychological dimension can tip the balance. Whether you’re prosecuting or defending a case with emotional-distress, cognitive-impairment, or capacity questions, the right expert psychologist elevates your case from argument to evidence. Licensed in Idaho and additional states (California, Oregon, New York, Connecticut), I bring multi-state forensic credentials and a free case‐fit consultation so your team can determine the best path forward.
If you have a matter where psychological expertise could make the difference, I encourage you to reach out for a no-obligation consultation and explore how we can work together.
Sincerely,
Dr. Lucas Klein
