Let me pose a question to you.

This is especially appropriate since you're an architect.

A fellow comes in to you and tells you that he used a 2" x 4" header above his garage door.........a garage with a second story above. He tells you that the header was fine and it supports the load perfectly.

Now, as an architect, you clearly know that this fellow is full of $hit and there is no way that such a header can do the job.

But, he claims to have the evidence that supports his position.

Do you accept his evidence.......or do you realize that he is clearly in error and that 2" x 4" is already bending significantly and may fail in the not too distant future?

Of course, you don't have any hard evidence to refute this fellow......because you'd never do anything so stupid as to put a 2" x 4" above an 8' door.

The analogy is identical.
