[Sigia-l] Can entering information twice prevent entry error?

[Fu-Tien Chiou]

Hi! 

I am wondering if there is any research that study the value/effectiveness of asking users to enter same information twice, in an application/registration form, to prevent entry error.  

Scenario here, one of my clients wanted to increase the number of 'correct' email addresses (for general website registration), and correct bank account number (for a financial application), as any client would.  They suggested to have users re-enter the email address and account number in the form, pretty much like the 'confirm password' you see everywhere. 

I know this may depend on the context and users.  However my hunch is, overall, it will have a negative user experience and not necessarily improve entry error. What do you think?  TIA for your response.  Have a nice weekend.
