How come some professions are declared "high risk of fraud" by banks, insurance, accounting firms? Your statement implies that there is an obvious truth that fraud is equally distributed among professions. Nothing in reality subscribe to this blank statement. For something that's Atlas Obscura worthy, it's been a few centuries that people have been making ranking of fraud level by trade. There's a book, whose name I can't remember, that explained how much you should expect to be swindled by the baker, the windmill guy, etc. It explained some of the common tricks each profession would use, how widespread the tricks would be, and therefore do an estimate on the most dishonest professions.
