Not everyone has an internal monologue
Unfathomable to me. My mind is constantly racing, playing out different conversations, interviewing myself in a variety of roles to navigate my thoughts on things (one day I'm the president of the US talking about foreign policy, another day I'm a big tech CEO navigating the diversity questions). I constantly have something in my ears to tune myself out, podcasts or music. After being diagnosed w/ ADHD I realize I'm probably on the extreme end of those with internal dialogue but to see a complete lack of it in others is very surprising.
