The Psychological Phenomenon of Confirmation Bias

Definition: A tendency to interpret information in a way that confirms one's preconceptions .

Confirmation bias is a huge enemy to the investor, its strangles clear headed analysis and negates the point of any research you make.

Ask yourself whenever examining an investment, " what empirical evidence is there available that constructively disputes my theory".

Objectivity is key to any investment decision big or small.
