simple. require everyone to work in cubicles that are closed off where your coworkers cant see you. all voice chats must be done without video and with voice modulation technology so that gender can not play a role. Also, the persons name must always be changed to J Smith to not hint at gender or race.
Or change the name 'J. Doe' so you can't even tell if they are alive or not.
Agreed, of course. But I still think it's a good idea to eliminate one opportunity for bias if we can.
