Humans are highly averse to making sure their actions are logically soundyes, but the illogical decisions of humans can be intuited or made to be understood, and thus also somewhat predicted. for example, a human deciding over someones social security benefits can be expected make a somewhat rational even if illogical decision, and in particular, past performance of a human can predict future performance, whereas for an AI this is completely unpredictable and therefore has a much higher risk of going wrong unexpectedly. also, humans can be reasoned with, again with a somewhat predictable outcome.
