Personal bias suppression
Suppression of personal bias can be described as a removal of the cultural and individual biases which human beings knowingly or unknowingly filter and interpret their perception of the world through during everyday life.
The idea that the opinions and decisions of people are based upon a consistent and unconscious tendency to notice and assign significance to observations that confirm existing pre-existing beliefs while filtering out and rationalizing observations that do not confirm pre-existing beliefs is a well established concept within the scientific literature. This is known is known as Confirmation bias and exists within varying degrees across all people but is significantly stronger for those with emotionally charged issues and deeply entrenched beliefs.
It seems that a human beings perspective of the world and their response to specific experiences is decided by running concepts through a complex set of cognitive filters which are primarily based upon pre-existing beliefs, past experiences, fears, prejudices, stereotypes, and cultural symbols. The experience of this component, however, seems to entirely suppress this filter and consistently shows people that many aspects of their personality, perspective and culture are merely subjective and often delusional ideas-- not an objective reality. This experience often leads onto deep states of introspection, insight and analysis which can create profound alterations in perspective that last anywhere from days, weeks, months or years after the experience itself.
