II. StayPsychology

Threat narrows the field it most needs open.

Bion describes groups fleeing the work by fighting, fleeing, or waiting for a saviour. Edmondson's psychological safety is the condition under which a group can stay with an uncomfortable fact long enough to learn from it. Kegan's immunity to change explains why the leader's own composure is so often the constraint.

V. The PracticePsychology

Expertise degrades without feedback that can wound.

Deliberate practice requires a task at the edge of capacity and feedback close enough to the act to be usable. Most senior roles supply neither, which is why experience and judgement diverge with seniority unless something is deliberately built to keep them together.
