In the setting you describe I think it will _reduce_ the errors to 20%

[psychoslave]

No, since the setting is not specifying the initial rate, it might as well increase or staying stable at 20%.

But there are other factors, like, is the amount of outcomes done also changing, thus affecting the absolute number of errors?

Also, does the side effect of disengage the person in most cases means it has side effects like not paying the same attention to what would stand out as a big issue that needs more attention and consideration than business as usual?

And so on
