Feedback social comparison

Williams, J. H. and Geller, E. S., Behavior-based intervention for occupational safety critical impact of social comparison feedback, /. Saf. Res., 31(30), 135, 2000. 

Because global feedback was just as effective as specific feedback when social comparison feedback was included, we presumed most of the 97 employees of the soft-drink bottling facility did not need an instructional intervention. They knew how to perform their jobs safely but needed some extrinsic motivation to follow the nine safety policies implied by the nine target behaviors. This was provided by a global percent safe score from a similar work group.
