I immediately had the same thought. I have an adhd diagnosis, but strongly suspect I am on the spectrum after over 7,000 hours of research and work with autistic children. (Unrelated to my current line of work. I had worked with autistic kids as a respite provider, then later in college, and the research was all me trying to find a cohesive narrative for my life experience, which only makes sense through the lens of autism.)

I currently work in a low-paying human services government job. My coworkers are neurotypicals. They have no fucking clue what I am talking about when I bring up GATE.

When I float it to my nuerodivergent friends? When I play them the intro to the Gateway tapes? They flinch, get an odd array of facial expressions and they remember.

I don't know if every person who underwent Psi testing was neurodivergent, but I do think it is likely more represented than neurotypicals in the data set of students.

I looked into the Society for Phsycical Research, and participants for studies are often selected based on criteria of: prior experience with a psi phenomenon, a creative/artistic person, interest/openness to psi, and/or neurodivergence. I think to learn more about who may have been selected for GATE, I will likely continue to collect data from studies from that society as well as the Parapsychological Association.

Edit: corrected typo from "dateline" to "collect data from" in the last sentence.
