What does it mean that identity flexibility?

Holding your identity lightly enough to update it when evidence warrants.

Example: You have identified as "the analytical one" for your entire career. It served you well as an individual contributor — you were the person in the room who found the flaw in every proposal, the gap in every plan. Then you got promoted to lead a team, and analytical rigor stopped being sufficient. The role demanded emotional attunement, motivational storytelling, and the willingness to make decisions with incomplete data. You could feel the new demands pressing against your identity like water against a dam. Every time you needed to rally a demoralized team with a vision rather than a spreadsheet, the old identity whispered: "This is not what you do." You had two options. You could grip the analytical identity tighter and fail at leadership. Or you could loosen your hold — not abandon the analytical capacity, but stop letting it define the boundary of who you are allowed to be. The people who make that transition are not the ones who were never analytical. They are the ones who held the identity lightly enough to expand it.

Try this: Choose an identity you currently hold strongly — one you would defend if challenged. Write it as a single declarative sentence: "I am a [label]." Now conduct an identity flexibility stress test. Write three scenarios in which that identity, held rigidly, would prevent you from doing something valuable. For each scenario, rewrite the identity statement in a flexible form: "I am someone who often [behavior], and I am also capable of [alternative behavior] when the situation calls for it." Notice the difference in felt experience between the rigid and flexible versions. The rigid version feels clean and certain. The flexible version feels less defined but more truthful. Sit with that discomfort. It is the sensation of holding your identity lightly — the prerequisite for updating it when the evidence changes.
