Dr Shawn Watson is a neuroscientist specialising in decision fatigue, and is regarded as a breakthrough mind in Alzheimer’s research.


We make around 35,000 decisions every day, but what actually is decision fatigue? 


In part one, Shawn joins Dr Alex George to unpack what happens in the brain when we’re making decisions, discusses the different neurotransmitters involved in the decision-making process, and reveals why we need to think of decision fatigue as a physical limitation - not a psychological one.


Plus, Shawn breaks down the consequences of decision fatigue and explains how we’ve ended up with an evolutionary mismatch when it comes to our daily decision-making.
