changing certification will fix a constant rate of failure.
The following bog is from a very close college.
Here are some excerpts from its first entry.
to err is human and all of us will eventually fail at any task no matter
how careful, skilled or knowledgeable we are.
failure rate for different classes of civil engineering structure is
between 1 and 5 percent...the constant at fault is the human factor.
Self-serving bias can prevent humans learning from their mistakes.
It is comic to think about it but half of us are below average in any
skill category but when asked, the majority will assess themselves as
above average.
It is disturbingly common to find that the less competent a person is at
a task, the higher the esteem in which they hold their own competence.
The catch 22 of engineering is that if you think you know what you are
doing, you probably don't while if you doubt you own skill, you may
actually be quite good at what you are doing.
