I've never heard the term "psychological safety", but I've heard the concept by other (better) names for ages. E.g. "open to productive disagreement" and "anti-yes-men", and many others terms that are vaguer but cover communication in general. Actually conforming to these has often been a struggle in most organizations, and picking a worse name won't help.
Laying them out side by side, it seems to me that this is in active conflict with "safe spaces", both in theory (no discomfort) and especially what I often see in practice (no disagreement allowed). To be useful, a safe space needs to be narrowly-scoped.
The term “psychological safety” has been around since the 1950s. It’s well defined and understood by people who study these things. There’s nothing wrong with the term.
