In reality, the horizontal bar is solid gray and only the

Our brains are quite susceptible to deceit. Just
hold a pencil up to one eye and look out the window – the pencil will appear see-through
because your brain fills in missing information to complete the view. Magicians and illusionists have taken advantage of these
shortcomings of our minds for centuries.
If you think you are generally less deluded than other
people, think again. A delusion is similar to a stealth computer virus – it operates
unconsciously. Our brain’s quest to eliminate cognitive dissonance is one such
What is cognitive
Cognitive relates to mental processes such as thinking,
reasoning, forming opinions, and remembering.
The word dissonance describes a lack of harmony, a discord,
clash or tension.
Cognitive dissonance is a ‘bad feeling’ that arises from holding two conflicting beliefs,

How does my mind
respond to cognitive dissonance?
If cognitive dissonance exists, we are programmed to reduce

Next time you catch yourself rationalizing (or feeling guilty,
embarrassed), try to identify the two underlying, clashing cognitions.
Understanding and accepting our natural responses to
cognitive dissonance can help you
- keep your calm when dealing with irrational
- increase self-awareness and make better
