My point in the original comment about the concept of immediacy of reinforcement is that it is a broader, evidence-based concept that encompasses what the author described. I thought HN users might get value from such an explanation as they could apply it to more aspects of their lives than just "doing things quickly." It seems as though your purpose is to argue with me over things I didn't say or ideas I don't hold, which isn't productive or meaningful to the HN community.
