That's pretty much how talking heads like Dr. Phil, Dr. Laura Schlessinger, Dr. James Dobson, etc. make their money--they have a degree in a completely different field that doesn't even remotely qualify them, and viewers think they're a good source of advice because they have "doctor" in the title.  Schlessinger's degree was in anatomy--she never actually learned jackshit about psychology or anything that could possibly be useful for giving people relationship advice. Which is all fun and games until there are kids raised by parents who think James Dobson is the authoritative voice of God.
