it’s like the boiled frog problem, we don’t notice small changes over time, but when thrown into boiling water (accident) it is a big surprise - painful. Many problems remain hidden because we have forgotten, failed to record, or haven’t questioned the original assumptions against those now accepted in the industry.
See double loop learning.
