A post from Activision Blizzard reveals details about King's Diversity Space Tool, which is used to help create more diverse characters for video games. This doesn't sound like it should be as hard as all that, but the post describes pretty complex technology for the process: "In 2016, King began developing a method for guarding against unconscious bias and exclusion when it came to the creation of their games and characters. At the time, this idea existed as an intangible philosophy, but the potential was obvious." An additional explanation has been added to the top of the post after it drew some backlash. This explains that the tool is used as a starting point, but it is not being used in isolation:

The objective of using the tool is to uncover unconscious bias by identifying existing norms in representation and acknowledging opportunities for growth in inclusion. It is not a substitute for any other essential effort by our teams in this regard, nor will it alter our company’s diversity hiring goals. Over the past several years, the development of the tool was done with the support of all our employee DE&I networks, and we collaborated with external partners to create an even more robust tool.

The tool isn’t meant to be used in isolation; teams would sit down with company DE&I staff to identify existing norms and then discuss, educate, consult, and collaborate on how a character’s representation is expressed beyond those norms. This process is intended to create a conversation where our developers, assisted by the tool, challenge assumptions, assess choices, and find opportunities for authentic representation to be fostered in our games.
