Personal bias suppression (also called cultural filter suppression) is defined as a decrease in the personal or cultural biases, preferences, and associations which a person knowingly or unknowingly filters and interprets their perception of the world through.[1]

Analyzing one's beliefs, preferences, or associations while experiencing personal bias suppression can lead to new perspectives that one could not reach while sober. The suppression of this innate tendency often induces the realization that certain aspects of a person's personality, world view and culture are not reflective of objective truths about reality, but are in fact subjective or even delusional opinions.[1] This realization often leads to or accompanies deep states of insight and critical introspection which can create significant alterations in a person's perspective that last anywhere from days, weeks, months, or even years after the experience itself.

Personal bias suppression is often accompanied by other coinciding effects such as conceptual thinking, analysis enhancement, and especially memory suppression. It is most commonly induced under the influence of heavy dosages of hallucinogens such as dissociatives and psychedelics. However, it can also occur to a much lesser extent under the influence of very heavy dosages entactogens and cannabinoids.


Established personal bias heavily influences how human beings act. People's decisions and opinions seem to be at least partially based upon a consistent and unconscious tendency to notice and assign significance to observations that confirm existing beliefs whilst filtering out and rationalizing observations that do not confirm pre-existing beliefs. This is a well-established concept within the scientific literature known as confirmation bias.[2][3][4][5] Confirmation bias affects everyone's thoughts to a varying degree, but its effects are significantly stronger in the case of emotionally charged issues and deeply entrenched cultural beliefs.
