Despite all the strident noise made about glue lines blocking some 
mysterious energy vibrations in bridges, no one with the measuring tools 
that have become available in the last 200 years has found this to be 
the case and published their results. At least that I know of. It 
remains one of the many near universal faith based "facts" that 
"everyone knows", and will remain so in spite of what Baldwin's R&D 
department or anyone else has found. It's just intuitive and obvious, right?

Thomas Kuhn once noted that people tend to not be convinced by evidence. 
Instead, outmoded ways of thinking die with those who hold them. That's 
not entirely true, unfortunately. Outmoded ways of thinking are passed 
down from generation to generation in the avoidance of understanding and 
the comfort of belief. It's always baffled me that so much energy is 
spent in defending these things.
