Still following the post above (about the flawed highly cited Clarivate list) check the paper that was put online on December 31 in the Journal of Informetrics:
"Our results demonstrate that...highly cited papers always exhibit higher variety and disparity..the RS and LCDiv both have a positive effect on citation impact. From the perspective of effect size, our results suggest that the effect of variety on citation impact is most significant, followed by disparity and then balance. These results indicate that variety is likely the most important interdisciplinary factor for citation impact"
