Heuristic Decision-making for App Selection [450-6E5]

Previous studies have found that user ratings were weighted more in app-selection decisions than a summary permission safety score. This result could have been due to the user rating for an app being read prior to the permission safety due to their locations. In the present study, we varied whether permission safety or user rating was located above or below the other and also whether safety was signaled by a lock icon or a shield icon. Neither of these variables altered the relative weightings given to safety and user ratings. Consideration is given to whether other presentation variables might get users to increase the relative weighting given to permission safety score.
