How can someone trained in medicine and a highly successful career in neuroscience believe in all that insane bullshit?
Religious faith is a belief based on emotion.
You can be highly intelligent, qualified and skilled in a particular area but if you believe in a supernatural being then it is an emotive and non-rational belief without any evidence to support it.
An intelligent person who is also religious, will often try to find "evidence" to support their belief.
We all do this with various emotions we experience, be it love, anger, sadness. The logical part of our brain attempts to rationalise and explain the belief we have based on an emotional response.
Being religious is effectively being in love. God loves you and you in turn love God, as a result you feel happy, content and stable in your relationship and your life.
I'm always reminded of the astronaut who drove cross country wearing a diaper to stalk an ex partner.
No matter how high your IQ, each of us will sit in our own shit, to prove and receive love.
