It actually takes a lot of experience to make the old wisdom, “if it looks wrong---it probably is wrong,” true.
Inspectors throw the phrase around as if there is a level of “obviousness” that is genetic or primal----as opposed to something that must be learned over time.
Even in teaching future home inspectors, it is common to tell the student that if it looks wrong there is a good chance it is wrong. But honestly, I am not sure that anything can “look wrong” unless we have some amount of training to know what a particular thing should look like when done properly. Over and over again I am asked if something is wrong by students and even seasoned inspectors. With each question there is either something wrong or not. The fact that there was a question leads me to think that something didn’t look quite right to the viewer or why the question?
Without knowledge of how things work, of what things should look like when they are functioning properly, how can anyone know if something is amiss?
Inspectors that rely on this concept to keep themselves safe from missing things during an inspection are on seriously thin ice I think.
The inspector’s “cumulative knowledge” of what things should look like must be very large indeed, or things that are wrong just plain won’t jump out at them---it will just elude their field of vision much the same way it eludes the field of vision of their clients. It is why we have a job---or at least it should be. Otherwise couldn’t the client merely rely on his or her own “if it looks wrong, it must be wrong” ability?
I was thinking about this the other day when I looked inside a wood burning stove and saw disintegrated secondary air chambers. I was quite sure I would be able to have my client take a look at these air chambers---even without knowing what they should look like new---and that they would know instantly something was wrong with them without having any clue what they were---or even what they were for.
I was correct---they had no clue what they were---but they knew something was wrong with them.
Did the disintegrated fire-brick in the same stove jump out in the same way?
No they did not.
Many things that must “jump out” at the inspector are not so obvious.
