Think You’re Smart? How Your Brain’s Hidden Biases Trick You Daily

We like to believe we’re rational beings, but beneath the surface, our minds are full of quirks and biases that distort reality. Let’s explore seven fascinating mental phenomena that reveal how your brain can trick you, often without your awareness.

Your memories are not fixed but reconstructed, influenced by your current emotions and beliefs. This dynamic rewriting shapes your identity and worldview.

Beliefs widely held by a group can be wrong, as shown by cultural myths and outdated science. Critical thinking and evidence-based reasoning are essential to avoid this trap.

Assuming causation from sequence leads to superstitions and false beliefs, like lucky charms.

The Halo Effect: One Trait Influences All
Attractiveness and height bias our judgments, affecting social and professional outcomes.

Ego Depletion: Willpower Runs Out
