#22 Social Neuroscientist: "What Everyone Gets Wrong about Dopamine & Serotonin"

Dr Taylor Guthrie is a social neuroscientist, researcher, and one
of the leading experts in how our sense of self emerges from our
relationships, our goals, and the powerful social forces around
us


We all assume we know what’s happening inside our own minds. But
what if the way you describe your identity—your inner narrative,
your motivations, your beliefs—turns out to be incomplete?


What if you’ve spent your entire life overlooking how deeply
social context shapes you? Taylor’s research suggests that most
people don’t truly understand the hidden processes guiding how
they think, feel, and behave


Expect to learn why the self is far more malleable than you might
believe, how close friendships literally alter the brain’s
activity, why dopamine is more about drive than pleasure, how the
default mode network weaves your memories into a cohesive story,
whether so-called “quick brain hacks” truly live up to the hype,
and the fascinating ways that shared group identity can both
unify and polarise us


This episode will make you question everything you thought you
knew about your own mind.
