A botched bank robbery, a secret identity revealed by a lemon, and a criminal so confident he believed he was invisible. This isn't just a tale of incompetence; it's an unmasking of a profound cognitive bias. Join the Deep Dive Team on The Undercurrent Uncovered as we peel back the layers of the Dunning-Kruger effect. We'll explore why those with the least knowledge often believe they know the most, and how this "double curse" can lead to spectacular failures. From history's most overconfident figures to the pitfalls of everyday certainty, we investigate the dangerous gap between what we think we know and what's truly lurking just beneath the surface.
