Your Mind

You won't have to believe whatever your mind thinks - much of it is biased, incomplete stories conditioned by the environment and your past. By other people's limited perspective and beliefs. 

The Root of Bias, Prejudice and Bitterness

The root of all prejudice, bias, and bitterness is either a lack of awareness and understanding of truth or a forgetfulness of it.

Experiences Generate Expectations

Experiences generate expectations. Expectations also generate experiences. This feedback loop is important in understanding how we develop our beliefs and biases, fall into cultural norms and create our often rigid views of the world from limited experiences. 

Biased Opinions

You will continue to always have your own biased, limited perspective or idealised opinions. There is nothing fundamentally wrong with these so long as you don't see your opinions as absolute truths and not impose them on others. There is also no need to fight off your biased perspectives, but to notice them and with curiosity understand them. They will eventually develop and evolve to something more effective and although absolute truth will never be reached, one can approach a more harmonised holistic perspective on life.  

What Affects our Decisions

Our beliefs and emotions cause judgements often biased in nature and often not entirely correct. The executive part of the brain (System 2 in Kahneman's terms) could make false deduction based on limited knowledge and biased perspective and beliefs.
