In the cases where you have an indirect correlation, all you have to do is make it easier to measure the source that actually causes your undesired effect. E.g if your customers assume only your male retail workers can help them with their electronics, you can make sure everybodies name badge says "Certified $PRODUCT expert".

In the latter situation businesses will do so anyway, they will just do it secretly and try to cover it up.
