机器学习方法尤其会受到不同数据偏见的影响。只针对当前客户进行训练的机器学习系统可能无法预测训练数据中未表示的新客户组的需求。当接受人工数据训练时，机器学习很可能会产生与社会上已经存在的相同的成体制偏见和无意识偏见<ref>{{Cite journal|last=Garcia|first=Megan|date=2016|title=Racist in the Machine|url=https://read.dukeupress.edu/world-policy-journal/article/33/4/111-117/30942|journal=World Policy Journal|language=en|volume=33|issue=4|pages=111–117|issn:0740-2775}}</ref> 。
