If duplicating a field is an effective method of validation, why isn't it commonly used for other important fields throughout most forms, i.e. credit card numbers, ssn, phone? We can't forget about the visual validation that users perform while filling out both paper and online form. If the individual understands that they need to enter their information accurately to get their desired outcome, the visual validation will most likely occur.
I have a theory that the appearance of a dup email field is a misunderstanding of the dup password field. Password fields are often duplicated because they are masked and therefore the user has no way to validate their entry. About a year ago I was trying to find research to back up leaving the second email field off of a registration form for a project. I wasn't successful in finding anything that supported either direction. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
