There's a strong bias toward confirmation. First, they fully expect it and are looking for it. Most of all, the actual professional - like any professional - has learned that it's unproductive to debate or educate the patient/customer; you just let them think they're smart and work around it. It's not your job to teach them the error of their ways, but to get your work done. In IT, I've had plenty of clients tell me the most ludicrous nonsense. You just work around it; IT is your job, not theirs; don't humiliate them. Be respectful to people; they have hard days too.
