brain“The human mind is a wonderful thing. Cognition, the act or process of thinking, enables us to process vast amounts of information quickly. For example, every time your eyes are open, you brain is constantly being bombarded with stimuli. You may be consciously thinking about one specific thing, but you brain is processing thousands of subconscious ideas.

Unfortunately, our cognition is not perfect, and there are certain judgment errors that we are prone to making, known in the field of psychology as cognitive biases. They happen to everybody regardless of age, gender, education, intelligence, or other factors. Some of them are well known, others not, but all of them are interesting.”
