Hi Rob, I haven't seen any specific research on this but, if this form is to sign-up for a newsletter, then I would argue that getting the maximum number of email addresses should be your goal, regardless of the optional data. You can always try to convince people to update their profile later in some way, or do survey, but at least you'll be able to start that conversation, rather than having no point of contact at all.
Good luck with your testing, I'd love to hear what you found out! Luis. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
