Read the following passage regarding legal epistemology and expert testimony.

In the realm of legal epistemology, courts have increasingly grappled with the phenomenon of "epistemic trespassing," a concept introduced to describe situations where experts in one domain make authoritative pronouncements in an adjacent but distinct field in which they lack formal credentialing or localized knowledge. The traditional Frye and Daubert evidentiary standards focus heavily on whether the methodology underlying an expert's testimony is generally accepted or scientifically valid. However, these standards often fail to address the more subtle danger of the epistemic trespasser: the expert who possesses legitimate, highly specialized credentials in a foundational discipline, but who seamlessly extends their analytical framework to answer questions that properly belong to a structurally related, yet methodologically distinct, discipline.

The pernicious nature of epistemic trespassing lies not in the use of pseudoscience or the absence of general expertise, but rather in the misapplication of valid science. When a cognitive psychologist testifies about the specific neurobiological mechanisms of a traumatic brain injury, or when a molecular biologist extrapolates from cellular degradation to population-level sociological trends, they are applying the robust epistemic confidence derived from their home discipline to a target discipline. This cross-domain application is superficially persuasive to fact-finders because the expert's broader ethos remains intact. The trespasser often fails to recognize their own boundary-crossing, operating under the assumption that the target domain's problems can be reduced to the foundational domain's mechanisms—a fallacy known as disciplinary reductionism.

To adequately safeguard the integrity of expert testimony, legal scholars propose a shift from purely methodological gatekeeping to "boundary-enforcement" protocols. Under this paradigm, courts must initially delineate the specific epistemological boundaries of the question at issue. Once the boundary is defined, the court evaluates not merely the expert's general scientific credentials, but whether their specific training provides the conceptual tools necessary to interpret the nuances of the target domain without reducing it to their own. A boundary-enforcement approach demands that an expert demonstrate localized competence in the target field's distinct evidentiary standards, rather than relying on the prestige of their foundational expertise.

Based on the passage's description of "epistemic trespassing" and "disciplinary reductionism," which of the following scenarios accurately embody the underlying principle of epistemic trespassing? (Select all that apply.)
