Sexual harassment is not a separate statutory cause of action. It is a form of sex discrimination prohibited by Title VII's bar on discrimination "because of . . . sex" with respect to compensation, terms, conditions, or privileges of employment 1, given content by the EEOC's guidelines at 29 CFR § 1604.11 and by four decades of Supreme Court decisions 2. That structure matters for expert work, because it means the expert is rarely opining on the ultimate legal question. The expert is opining on what a competent employer should have had in place, whether the employer's response met professional standards, and — in a different posture — on the psychological consequences of the conduct.
Four decisions define the field, and an expert who cannot navigate them will be limited on Daubert or ineffective at trial.
Because the Faragher-Ellerth defense has two prongs, it generates two distinct expert assignments. On the first prong, the expert evaluates the employer's prevention and correction apparatus against professional practice: whether the anti-harassment policy defined prohibited conduct in usable terms, whether it provided multiple reporting channels that bypassed the alleged harasser, whether training was delivered and to whom, whether complaints were investigated promptly by someone competent and sufficiently independent, whether the investigation was documented, whether interim measures protected the complainant without penalizing her, and whether the corrective action was reasonably calculated to stop the conduct. On the second prong, the expert addresses whether the complaint process was in practice accessible and safe to use — a question on which organizational psychology research on non-reporting is frequently relevant.
A third, separate assignment is damages. Psychological injury is not an element of the claim under Harris, but where emotional distress damages are sought, a forensic psychologist or psychiatrist evaluates the plaintiff's condition, causation, pre-existing history, and prognosis. That witness should be distinct from the HR or organizational expert; combining the roles weakens both.
Attorneys and experts still cite the EEOC's April 2024 Enforcement Guidance on Harassment in the Workplace as though it were settled agency authority. It is not. A federal court declared portions of it unlawful and vacated them nationwide in May 2025, and the Commission subsequently voted to rescind the guidance 8. Expert reports that rest on it are exposed. The EEOC's earlier Enforcement Guidance on Vicarious Liability for Unlawful Harassment by Supervisors, which implements the Faragher-Ellerth framework, remains the more durable agency reference 9. State law has moved in the opposite direction from federal law in several jurisdictions, with statutes that lower the severe-or-pervasive threshold, extend limitations periods, restrict nondisclosure and non-disparagement terms in settlements, and extend protection to independent contractors — so the expert must be current in the specific forum, not merely in federal doctrine.
The two credible profiles are the senior HR and compliance practitioner — SHRM-SCP or SPHR, with real experience writing policy, delivering training, and conducting investigations — and the doctoral-level industrial-organizational or social psychologist who can speak to reporting behavior, power dynamics, and organizational climate research. Investigator-side experience is particularly valuable, because the quality of the investigation is usually where the first Faragher-Ellerth prong is won or lost. What courts consistently exclude is testimony that tells the jury the legal conclusion — that conduct was "severe or pervasive" or that the employer "is liable." The expert's job stops at professional standards and organizational practice.
Harris v. Forklift Systems requires "an objectively hostile or abusive environment — one that a reasonable person would find hostile or abusive — as well as the victim's subjective perception that the environment is abusive," and holds that no psychological injury need be shown.

FAQ
There are two credible profiles. The first is a senior HR and compliance professional, typically SHRM-SCP or SPHR certified, who has personally written anti-harassment policies, delivered training, and conducted investigations. The second is a doctoral-level industrial-organizational or social psychologist who can address reporting behavior, power dynamics, and organizational climate research. Investigation experience is the most valuable single qualification, because the quality of the employer's investigation is usually where the first Faragher-Ellerth prong is decided.
Where a supervisor's harassment did not culminate in a tangible employment action, the employer may avoid vicarious liability by proving both that it exercised reasonable care to prevent and promptly correct harassing behavior and that the plaintiff unreasonably failed to use the preventive or corrective opportunities provided. Experts address the first prong by evaluating the policy, training, reporting channels, investigation quality, interim protective measures, and corrective action against professional standards. On the second prong, experts address whether the complaint process was in practice accessible and safe to use.
No. Harris v. Forklift Systems holds that so long as the environment would reasonably be perceived, and is perceived, as hostile or abusive, there is no need for it also to be psychologically injurious. Psychological evidence still matters where emotional distress damages are claimed, but that is a damages question requiring a forensic psychologist or psychiatrist — a different witness from the HR or organizational expert, and one whose opinion should not be blended with standard-of-practice testimony.
Under Vance v. Ball State University, an employee is a supervisor for Title VII vicarious liability purposes only if the employer has empowered that person to take tangible employment actions against the victim — hiring, firing, failing to promote, reassignment with significantly different responsibilities, or a decision causing a significant change in benefits. Merely directing another employee's daily work is not enough. Where the harasser is a co-worker rather than a supervisor, the employer is liable only for its own negligence in failing to stop conduct it knew or should have known about, which shifts the expert's focus to notice and response.
That question should be avoided. Courts routinely exclude expert testimony that states the legal conclusion, whether framed as severe or pervasive, hostile, or liable. Admissible testimony describes what professional standards required of the employer, what the employer actually did, how that compares to accepted practice, and — for psychologists — what the research says about reporting behavior and organizational climate. The jury draws the legal conclusion.
In general, employment expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are professional experience, forensic experience, academic qualifications, industry certifications, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
