Personal bias suppression from 25I-NBOH

Personal bias suppression, also referred to as cultural filter suppression, can be described as a decrease in the personal, cultural, and cognitive biases, preferences, and assumptions through which a person normally filters and interprets their perception of the world. These biases are an inherent part of everyday consciousness and serve as mental shortcuts that shape how one perceives events, evaluates information, and forms opinions. Under the influence of this effect, these normally invisible filters become apparent and lose their power, allowing a more raw and unmediated engagement with one's own thoughts, beliefs, and perceptions.

The suppression of this innate filtering tendency often induces the realization that certain aspects of a person's personality, worldview, cultural conditioning, and deeply held beliefs are not reflective of objective truths about reality but are instead subjective opinions, unexamined assumptions, or culturally inherited biases. This realization can be startling in its clarity, as beliefs and preferences that previously felt like fundamental aspects of one's identity are suddenly revealed to be arbitrary constructs that could easily have been otherwise had one been raised in different circumstances.

This often leads to or accompanies deep states of insight and critical introspection in which one can examine their own beliefs, habits, relationships, and life choices with unusual honesty and objectivity. Analyzing one's beliefs, preferences, or associations while experiencing personal bias suppression can lead to genuinely new perspectives that would be extremely difficult or impossible to reach while sober, as the normal defensive mechanisms that protect one's ego and existing worldview are temporarily suspended.

Personal bias suppression is most commonly induced under the influence of moderate to heavy dosages of psychedelic compounds such as LSD, psilocybin, mescaline, and DMT, as well as dissociative compounds. It can also occur to a lesser extent under the influence of very heavy dosages of entactogens like MDMA and cannabinoids. The depth and character of the effect tends to scale with dosage, with lighter doses producing subtle shifts in perspective and heavier doses potentially triggering fundamental reassessments of one's entire belief system and identity.

Personal bias suppression is often accompanied by other coinciding effects such as conceptual thinking, analysis enhancement, novelty enhancement, and memory suppression. The insights generated during this state can create significant and lasting alterations in a person's perspective, behavior, and values that persist for days, weeks, months, or even years after the experience itself. This enduring impact is one of the reasons that psychedelic-assisted therapy has shown promise in treating conditions rooted in rigid thought patterns, such as depression, addiction, and post-traumatic stress disorder.
