Some amount of fear is required for our survival, but most of even those essential fears appear to set in only a little later in life, and by observation of fearful behaviors in adults. Scientists have found that two fears are inborn in humans—the fear of falling, and that of loud noises.

Short of zapping our amygdalas, which seems a bit extreme, constant and scientific exposure to whatever it is that we fear seems to be what will do the trick.

The full article does in fact address this! I perhaps should have been more clear about what a natural phobia is and included a long rambling bit about how the visual processing stuff is being poorly explained in that article - recognition of the patterns they’re talking about are absolutely present but do not contribute a fear response in their own. The important part however is that they can be reversed!
