But laziness around something that dispropotionately impacts people based on their race is racist. If you know your system has a harder time training against non-white faces, and you choose to train it only against white faces to be lazy, that's still explicitly racist. This isn't even a case of negligent racism ("oh well I didn't know my system wouldn't work for people with darker skin because only my white coworkers tried it out"). The example here is a case of the engineer explicitly deciding to avoid the harder case of darker skinned individuals, knowing that the results would be poorer for those individuals, and thinking it doesn't matter if the system doesn't work well for people with darker skin. That is explicit racism.
