Confidence Versus Bravado
Launch library · evergreen read

Genuine confidence in an answer tends to sit calmly, without needing to be asserted repeatedly or defended against a challenge that has not actually been raised. Bravado, by contrast, often arrives louder than the situation requires, as though anticipating doubt before any doubt has been expressed.
Distinguishing the two matters because they call for different responses. Genuine confidence can usually withstand a probing follow up without strain, while bravado sometimes cracks under the same gentle pressure, revealing a less certain position underneath the assertive surface. Bravado, once tested gently, sometimes reveals a considerably less settled position than its confident tone first suggested.
A careful interviewer tests rather than assumes: a calm follow up question, asked without hostility, tends to reveal which of the two is actually present far more reliably than simply listening to the tone of the original answer alone. A calm, unhurried follow up tends to expose the difference more reliably than the original tone of voice alone.
