Since it links to information hazards [0] it makes me want to write up my experiences with psychological damage, ethics, and how they relate to information hazards. Someday it'd be fun to write about.
There are some information hazards out there that are really, really deep, scary, and also funny, once you realize how easy they make it to e.g. manipulate people without using any of the typical tricks, or even to bring decades-old relationship problems to an end in a single conversation. (Or how they make it obvious that a powerful thing to do is let yourself talk...to yourself! Weird insights abound)
For example you can effectively direct people in a given context by identifying the cues they give you for the type of information-consumer they are.
Some people will read that and hear "leadership" or "NLP" but it's quite different.
For some it may be as easy as noticing that they talk or write in metaphor, or they focus more on "we" than "me" in specific ways.
This can then be mapped to a set of low-energy, high-stress perspectives that the individual values in different sets of ways. Once you tease out those ways...well, this is information hazard, it's the option of turnkey psychological damage in a very straightforward way, and it's a huge ethical thing.
I thought it was weird that I had to learn about ethics to get a certain certificate to teach people about personality typologies, but then it really hit me later on.
