Meir Shemla has co-published a 2018 paper researching diversity management practices in organisations. He said in a statement that when members of a team are different from each other, they perceive, experience and understand reality differently, which may impede their ability to work together. In research, he found that cohesion and trust among very diverse teams tends to be low. Shemla said achieving equality in an organisation doesn't necessarily mean achieving performance, as the two goals conflict with one another, and that many diversity policies "ignore the fact that you actually need to manage that diversity, which requires a different set of processes and actions."
