In what ways might a devil's advocate hinder the group process what other strategies can help reduce groupthink?
If you are talking about reducing groupthink, just expressing different views frees others to some extent for expressing views that vary from the group opinion.
I did my doctoral dissertation on the effect of a partner (one who shared views different from the group) on conformity to group opinions. Any expressed deviation from the group opinion seems to make others feel freer to express other deviant opinions.
I hope this helps a little more.
