The number and ethnicities mentioned are examples of what I saw looking at many MH results on YouTube.
MH rightly puts such cases in the low confidence category, but is it enough ?
1. If such patterns exist on a regular basis, this is likely a systematic error that MH ought to solve.
2. Due to the potential psychological effect, wouldn't it be preferable to put such cases in an "Conflicting" or "Unknow" category ?
