There is a subtle, often unconscious filter which hides deep within us. I am not sure if there is a consistent origin. I suspect it is born in our early experiences where the influence of events and words touched us like truth. Once planted, our eyes and mind began to reinforce its home within us. At some point we forgot about it, rarely recognizing how frequently it changed our ways of seeing life around us.
Understanding the existence of unconscious bias takes time and self-reflection. As I continue to discover different forms of bias within me, I still struggle to see where and how it originated. Given it seemingly effortless ability to multiply and morph, I have turned my attention to the role it plays with my decisions and choices.
