Why Your Brain Loves Hammers

We often suffer from a bias called the law of the instrument, where we force every problem to fit the tools we already know. If you only own a hammer, you will start seeing every challenge as a nail that needs hitting.

This psychological trap explains why experts often fail to solve problems outside their specific comfort zone. Instead of choosing the best strategy for a task, we subconsciously prefer methods that feel familiar and convenient. This tendency can make us incredibly inefficient, as we ignore better solutions just because they require learning something new. Keeping an open mind is the only way to avoid turning every situation into a nail.
