• Cognitive fusion trades flexibility for focus. You will be strongly driven and capable of focusing on just the thing that’s your in mind, at the cost of being less likely to notice when that thing is actually wrong.
• Cognitive defusion
  • In one way or the other, all of these highlight the fact that the thought or emotion is just a mental construct, making it easier to question its truthfulness.
• Some simple defusion techniques suggested by ACT include things like noticing when you’re thinking something bad about yourself, and prefacing it with “I’m having the thought that”. So if you find yourself thinking “I am a terrible person”, you can change that into “I’m having the thought that I am a terrible person”. 
  • Or you can repeat the word “terrible” a hundred times, until it  stops having any meaning
• Or you can see if you can manipulate the way that the thought sounds like in your head, such as turning it into a comical whine that sounds like it’s from a cartoon, until you can no longer take it seriously
