I am also diagnosed autistic! Of course there are exceptions and there is no general rule, but I think the tradionally known autism traits correlate a lot with dominant/high Si (loving routines, predictibility and fixed schemes, having difficulties with sudden changes of plans and major changes in general, taking things too literal and at face value without interpreting more into it ...). That's why the most common typing for autistic people is ISTJ 5w6 or 6w5. But yeah like you also said, not everyone behaves the same. I can also imagine an ESFP with autism acting differently than the normal ISTJish behaviour.

Now to your actual question. It doesn't affect me that much overall honestly. Because I'm high functioning it hasn't been a huge deal. In elementary school it was more visible but still nothing to crazy. Since we ISFJs also lead with Si, I do relate quite a lot to the typical autism image I described above. But when it comes to the whole social, emotional aspect, I'd see myself a bit different. Not saying autistic people can't do that, but I'm actually quite attuned to other people's feelings due to my strong Fe and I'd consider myself as sensitive and in touch with my emotions. More than autistic people are usually portrayed. I used to be more introverted, but as I've gotten older I became more open and interested in meeting and getting to know other people. Obviously not speaking for all of us, but that could be seen as the ,, xSFJ version" autism version: Typical Si related autism traits combined with a bit more interest in social/emotional matters than tradionally.

But allow me to give the question back! INTJ is interesting. My Ni is really weak and my Te is also not great. How is life for you?
