BJ Fogg's Behavior Model
My Behavior Model shows that three elements must converge at the same moment for a behavior to occur: Motivation, Ability, and Trigger. When a behavior does not occur, at least one of those three elements is missing. Using my Behavior Model (FBM) as a guide, designers can identify what stops people from performing behaviors that designers seek. For example, if users are not performing a target behavior, such as rating hotels on a travel web site, the FBM helps designers see what psychological element is lacking. The FBM also helps academics understand behavior change better. What was once a fuzzy mass of psychological theories now becomes organized and specific when viewed through my Behavior Model.
