Fear is a universally felt emotion. Presentations of phobias are very personal and prevalent in the modern day, despite their evolutionary roots. Through my research, I am categorizing phobias into three distinct categories; evolutionarily preserved phobias, trauma-induced phobias, and those that represent a co-opting of the evolutionary fear response to more modern triggers, to which our biology would have no predisposition of fear. Additionally, I want to understand if these various phobias affect different groups of people with different severities and track what correlations may exist.
