Governor Andrew Cuomo (D-CA) mentioned this in a press briefing in May, 2020.
Issue: We typically ask, “How are you doing?” without much thought. It’s more like saying, “Hi”.
Instead of asking: Q: How are you doing?, the re-frame is: Q: How are you doing, really?
The inference within the second version sends a qualifying message (“really”) to the recipient you actually are interested/concerned about their current state (emotional/physical).
The assumption is that you will then listen. How you decide to engage, offer help/service, arises as needed.
