Cognitive Heists series #3: The Call Is Coming from Inside Your Mind
📞 The Call Is Coming from Inside Your Mind
Welcome to #3 of the "Cognitive Heists" series. The Voice in Your Head -- Authority, Audio Deepfakes, and the Power of a Familiar Voice
In 2019, a UK energy firm received a call. The voice on the other end sounded exactly like the CEO of their German parent company.
The request? Transfer €220,000 immediately to a trusted vendor. It wasn’t the CEO. It was a deepfake.
This was the first confirmed deepfake voice fraud used to commit corporate theft—and it’s only the beginning.
This issue dives into:
🎧 Why voice is one of the most powerful trust signals—and why that’s dangerous now
😨 How vishing, voice cloning, and audio deepfakes hijack your certainty
👻 A classic urban legend (yep—the babysitter and the call from inside the house)
🧠 The psychology of obedience, panic, and auditory illusion
🧯 And how to train your brain to pause the response before the wire transfer
In a world where your boss’s voice can be faked, what part of your brain do you not listen to?
A couple relevant sources related to AI based voice scams:

Cognitive Heist series #2: The Bait Man

Truth Hurts. So We Lie.
Ok. This one's pretty uncomfortable. It's about the lies we tell ourselves and why we believe them.
We all like to think we’re rational. But the truth is, our minds are masters of defense... not just against deception, but against discomfort.
In this issue, I explore the mental machinery behind "motivated reasoning" and "cognitive dissonance." These are mechanisms we use to try to protect ourselves from inconvenient facts.
🔍 Why we reject information that threatens identity
🛡️ How our beliefs start defending themselves
🎭 Why feeling right often beats being right
This theme hits at the core of the Deceptive Minds mission: a newsletter about how we are fooled, how we fool ourselves, and what we can do about it.
