Thanks for the responses, but I think I didn't explain it very well. What I have is a weight loss web service. The user can set goals, say 20 lbs, and that goal can then be broken up into milestones, say every 5 lbs. So in this case, the user has a 25%, 50%, 75% and 100% milestone every 5 lbs. With each milestone they reach, they get rewarded with cash or points or other incentives.
>From a usability perspective, the current next milestone and its reward is the only one the user really needs to know. So if the user has already lost 6 lbs, the next milestone is 50% and its reward could be a $10 gift card. They don't need to know the 75% or 100% rewards because that info isnt relevant yet (progressive disclosure). What I'm asking is, from a persuasion perspective, would showing all the milestones and rewards (instead of just the next current milestone) produce a higher goal completion percentage? Some research I've found seems to suggest it could. I'm referring to the endowed progress effect, but that only states that by giving the person a "head-start" they would be more likely to finish. I think this technique could also be applied, but it still doesn't answer my question. Can anyone point me in the right direction for some research that would either prove or disprove this theory? (Anecdotal answers are also welcome, but they might be less effective when I present it to upper management ;) Thanks, Brian . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
