Are All Autistic People Introverts?
Autistic or not, a great number of us are introverts. Sometimes other people or large crowds of people can take a lot out of you. However, those with autism may seem like they do not want to speak or interact with those outside of whom they regularly see or speak with, but this is not always the case.

The only difference is that since those with autism have communication barriers, speaking or interacting with others can be an exhausting endeavor for them to go through with. This is why going through this type of communication or event is tough for them, but it does not mean that they do not like to do it.

Those with Autism are More Than Likely Not Introverted
Those with autism find it hard to communicate and open up to those around them, which is natural in their normal state. However, it does not mean that they do not want to be around others or that they prefer time alone. In fact, many with autism actually enjoy being next to those that they love and holding new friendships with others who they come across.

Some people who have autism may also be introverts, but the two are not directly linked to go hand in hand. Just like anyone else who has a sort of social anxiety, it may just be the particular or specific person who is the introvert and not necessarily something that they have separated from this.

There are quirks that those with autism have, and sometimes it can be mistaken as wanting to be alone, or perhaps a little bit odd, but this does not mean that they don’t want to share how they feel, what they are thinking, or even what they enjoy with the company of others. This is a common misconception of those with autism.
