does not match the particular facts of this case—are similarly appropriate grounds for cross-
examination but not for outright exclusion. See Jn re Mirena IUD Prod. Liab. Litig., 169 F.
Supp. 3d 396, 419 (S.D.N.Y. 2016).
Next, Dr. Dietz provides several opinions on “indices in determining the credibility of a
victim’s claims.” Notice at 10. The first of these indices is whether “the core details” of an
accusation remain constant over time. /d. The second is that an alleged victim’s “emotional
distress [is not] predictive of the truthfulness of the allegation.” /d. at 11. And third, that victims

her clinical capacity, she does not “go out and verify any part of what’s being told in the clinical

determine whether something is or is not true.” /d. at 40. Therefore, Dr. Dietz’s opinion about
