1605 +
1606 +Study Scale:
1607 +
1608 +62 studies, 332 effect sizes, 10,186 participants (Black and White Americans).
1609 +
1610 +Covers the period 1956–2022.
1611 +
1612 +Cohen’s d Effect Sizes (Model-Free):
1613 +
1614 +Black viewers: d = 0.50 → strong, consistent ingroup preference for Black models.
1615 +
1616 +White viewers: d = –0.08 overall; pre-2000: d = –0.16 (ingroup); post-2000: d = +0.02 (outgroup leaning).
1617 +
1618 +Regression Findings:
1619 +
1620 +White viewers’ preference for Black models increases by ~0.0128 d/year since 1956 (p < 0.05).
1621 +
1622 +By 2022, White viewers showed positive directional preference for Black endorsers.
1623 +
1624 +Black viewer preferences remained stable across the 66 years.

1626 +
1627 +{{expandable summary="🔬 Findings"}}
1628 +
1629 +Primary Observations:
1630 +
1631 +Ingroup favoritism is evident: Black viewers consistently prefer Black endorsers.
1632 +
1633 +White viewers’ preferences have shifted significantly over time toward favoring Black endorsers.
1634 +
1635 +Temporal Trends:
1636 +
1637 +Turning point: Around 2002–2003, White viewers began showing a positive (though small) preference for Black endorsers.
1638 +
1639 +Moderator Effects:
1640 +
1641 +Low anti-Black prejudice and low White ethnic identification correlate with greater White preference for Black endorsers.
1642 +
1643 +Economic hardship (e.g., high unemployment) slightly reduces White preference for Black endorsers.
1644 +
1645 +Identification Model:
1646 +
1647 +Preference changes are stronger when outcomes measure identification with endorsers (e.g., similarity, attractiveness).

1659 +
1660 +Limitations:

1662 +Only examines Black and White racial dynamics—doesn’t cover Hispanic, Asian, or multiracial groups.
1663 +
1664 +72% of effect sizes are from student samples (not fully generalizable).

1666 +Social desirability bias may affect lab-based responses.
1667 +
1668 +Suggestions for Improvement:
