I have just spoken to yet another friend who suspects that they may be Neurodivergent. They are not interested in seeking a diagnosis for various reasons but this means they will never be picked up in the statistics. Anecdotally, this isn't unusual amongst my friendship circle and I now suspect that a very large percentage of the population believe they may be ND even if they have no diagnosis and have never seen a professional about this. So out of interest please vote:
YABU: if you think you are Neurotypical
YANBU: if you believe you are Neurodivergent, even if you don't have a diagnosis
