Profile human behavior. Interpret meaningless chicken scratches without laughing.
$$: A good handwriting analyst can make $100 per hour at a cocktail party; big ones who are asked to authenticate major documents are very well paid, particularly since they rarely are capable of being definitive and mostly offer a raft of bulls**t rationalizations and excuses for not being more certain of anything.
The upside: Great glow of science about a whole bunch of mumbo jumbo. Get to hang with other graphologists, who are really fun at parties.
The downside: Clients get very annoyed when they rely on you to authenticate things and all you can give them is a raft of halting excuses and mumbling horses**t.
The dark side: Sudden conviction that life is meaningless and the truth is essentially unknowable.
Where you go from here: Water dowser.
