Research suggests the introducing automated decision aids does not always reduce human error, but can isntead create opportunities for different kinds of errors.
Participants with an aid :
Missed events when not prompted about them
Followed auto-recommendations even if it contradicted their training and other indicated
When people heavily rely on automated systems, taking the path of least cognitive resistance, it can lead to a higher possibility of errors.
