> I read the deck not the videos, but their is a section on “nice” versus "kind" slice that is the complete opposite of your straw man
Thanks for drawing attention to the existence of the slide deck, that was much more easier to read than the video.
I think I understand why OP is reacting to the word "kind", it is a bit of a misleading branding, and the content is also not exactly coherent about it. There is an extra emphasis on considering the other persons' reception of the communication, but then there is an inclusion of assertive communication as you've pointed out. A more realistic title would have been "how to work and communicate effectively".
> In fact, psychological safety is what creates an environment where actions and decisions can be discussed and critiqued rationally rather than emotionally.
Again I think the connotations of term is problematic, in comparison to your pretty good of an explanation of what it should be about. After all psychological safety depends on the other side's psychology, so for a narcissist that would mean actually not threatening their myth of personal superiority, and bringing rationality to discussion would not necessarily be comfortable for them.
I think a much better approach can be considered through virtue ethics. There is no being fair to the other people while not being fair to ourselves. So there is a golden mean between giving consideration to their point of view vs. requesting consideration for our own point of view and there is no algorithmic approach that can find that point for us. We can't get lost in emotional contagion with the other persons' feelings (think of a surgeon unable to operate a kid because they are empathizing too much), just like we can't get lost in our own feelings (every callous, bullying manager or lead we've encountered).
Also "engineering" kindness sounds very objectifying and manipulative. Please do not engineer me, I am a human. Tell me the good reasons to be kind, and let me decide for myself. If being kind is "good", people would naturally take it up.
