The idea
The book's lesson from Marcus: relatedness is sustained by continuous conditions, not by single events, and an opening without structural support tends to revert.
In practice
Marcus, two years on: "Some things. Not everything. More than before."
Where people slip
The book calls this not failure but the outcome the research predicts when an opening is not followed by durable support.
