Changing Customer’s Perception

An orange juice company I worked for
tried to change the perception of
not-from-concentrate vs from-concentrate juice. 
Despite the from-concentrate juice
scoring higher in blind tastes,
customers insisted that the
not-from-concentrate juice was “better.” 

Decades and millions of dollars
in advertising later and
the perception remained. 
The juice company finally gave up
and launched its own
not-from-concentrate product. 

A couple weekends ago, 
my writing group had a forensic scientist speak.  
He insisted that the crime shows (like CSI)
had it all wrong.  

So which source of information
should we use in our romance novels?  
The crime shows. 
Why? 
Because that is what the customer expects.
