Be the SD in an SΔ world! Yes, it sounds a little odd to say, but there is some important meaning to it. SD = Discriminative Stimulus. SD is a signal that reinforcement may be available. SΔ = stimulus that is in the environment that signals the non-availability of reinforcement. So, in short, this is a nerdy behavior analyst way of saying that we need to be the change that the world needs because behavior goes where reinforcement flows. We can and should do better, and doing better starts by being that very much needed change of reinforcing the change the world needs.
