Podcaster's Notions about Gut Feelings Interesting but Possibly Flawed

On a recent Mindset Mentor podcast of his, personal development coach Rob Dial discusses his opinions about intuition, more specifically what he terms "gut feelings", in making decisions about others and situations.  Announcing that it was science, he claims that we all have a separate nervous system from our brain-controlled Central Nervous System (CNS): the Enteric Nervous System (ENS), that exists with more than 500 million neurons within the walls of our digestive system.  This much I go along with...Michael Gershon discovered the ENS in the late nineties, according to Dial.  What I do have difficulty automatically accepting is Dial's notion that connects the ENS, or "second brain" as Gerson terms it, with the idiomatic expressions "gut feeling" and "butterflies in stomach" as if it's giving me independent information.  Dial goes further and says that the ENS, unlike the brain which often focuses on the future and past, is wholly rooted in the present and makes itself known through feelings.  The part of his show that I did get was that we shouldn't carelessly dismiss those feelings and signals...regardless from where in our bodies they arose.  If you want to believe that you're a multiplicity of thinking systems, go for it...I tend to think that it's a lot more complicated and interrelated (and interdependent) than that.  Rob Dial is good in his "lane" of self-improvement advice and coaching, but he's not a scientist...neither am I.  Just because he or I may have learned a little about something doesn't qualify either of us from going downtown with it and attributing special narratives where they haven't been shown to apply...
