2. How should cultural cognition dynamic influence evidentiary rulings, including assessments of prejudicial impact?
3. Should the judge put any special limits on closing arguments to avoid exploitation of cultural cognition?
4. Are there procedural devices—ones relating to form of proof at trial, to jury instructions, or to jury deliberations—that might help to mitigate cultural cognition?
5. How, in opinion writing or otherwise, can the judge anticipate and minimize the impact of cultural cognition on how members of the public perceive the impartiality of trials and appellate decisions?
