The identification-bias correlation is close to zero with large study variation

Evidence

In fact, the vast corpus of work demonstrating the near universal prevalence of ingroup bias in intergroup attitudes and behavior (Brewer & Brown, 1998; Hewstone, Rubin, & Willis, 2002) can be taken as support for the core proposition of Social Identity Theory that ingroup members are strongly motivated to seek some positive distinctiveness for their ingroups in relation to outgroups. Nevertheless, attempts to test another central hypothesis of Social Identity Theory – that these manifestations of ingroup bias should be correlated with strength or importance of group identification – have met with mixed success. One early review of studies investigating the identification–bias relationship concluded that the overall correlation was close to zero with considerable variation among studies (Hinkle & Brown, 1990). — , Rudman, Laurie A - On the Nature of…, 441 (#corroborates, via linked claim)
