Good call. I can’t remember if kahneman talks about it in the book but there is a fascinating experiment on people who have had a procedure that severs the connection between the left and right hemispheres (epileptics). They exhibit the impulsive tendency to explain away sensory evidence that contradicts their previous statements. The theory is that speech centres inhabit the left brain and in the absence of a measured analysis by the right hemisphere they just make something up without apparently thinking it through.







I smoked a lot of weed as a young adult. Looking back on that time I believe that I was escaping from the endless intrusive thoughts. Focusing my mind on any sort of work was difficult and I used all sorts of substances to get by. My typical usage profile is to find something appealing and use the shit out of it until it becomes a problem, spend time recovering and repeat with the next chemical. After recovering from heroin addiction it became obvious that it was not normal behaviour and I sought medical advice. They diagnosed ADHD and many of the past events started to make sense. I use routine to bring order to my life. I meditate to calm the mind. The medication allows me to focus and prioritise tasks. I think of my life in two starkly distinct chapters, pre and post diagnosis. I feel happy and the thought of taking substances seems like a strange thing to do.
