A deepfake voice or video impersonating a senior executive is effective for a very human reason: most people are wired to respond quickly and without much friction when someone with authority asks for something urgently, especially over a channel, a phone call, a video call, that used to be hard to fake convincingly.
That instinct, authority bias, isn't a flaw unique to any one person. It's a normal social reflex that attackers have simply learned to exploit now that the technology to convincingly fake a senior voice or face is cheap and accessible.
The fix isn't teaching people to distrust their leadership: it's building a simple, non-negotiable verification habit for anything involving money or sensitive access: a second channel, a callback to a known number, a policy that applies even when the request sounds exactly like the CEO. Especially then.
