Jake discusses the emotion of fear in this episode. What is the adaptive function of fear? What does fear tell us is going on in our environment? In brief, fear tells us that there’s a threat or a danger present. It’s probably safe to assume that compared with our ancestors, in this day and age we have little to fear in our day-to-day lives. Why then in places like the US, Europe, and Australia is there a reported general increase in overall anxiety? Jake discusses fear (both rational fear and irrational fear) and anxiety further and talks about how the two are related.
