A manager’s belief about an employee’s limits can become part of what keeps the employee limited.
An employee struggles early in a role, so the manager starts giving them less responsibility.
They’re left out of important meetings, given fewer stretch assignments, and asked to get approval before making decisions they might otherwise learn to make on their own.
Over time, the manager sees fewer examples of the employee succeeding independently and becomes even more convinced that the employee “isn’t ready.”
The original concern may have been reasonable, but the problem is that the manager’s response can start shaping the evidence they use to confirm it.
Once we decide what someone is capable of, it becomes easy to notice the moments that fit the story and overlook the ones that don’t.
That doesn’t mean managers should ignore performance history or hand people responsibilities they aren’t prepared to handle.
It means conclusions about capability should remain open to revision.
Has the employee improved? Are they behaving differently now? Have they had a recent opportunity to demonstrate more responsibility?
Good management requires making sure yesterday’s limitations don’t become tomorrow’s ceiling.
