Perhaps a condition where participants are thinking about the outgroup but do not engage in the contact element, and/or a condition of imagined contact with the ingroup. Depends on what the question is!
We have a new imagined contact intervention and want to compare it to the most common control group! Doing the same intervention without the contact component would be very difficult to do unfortunately.
