There was a website that estimates IQs (emphasis on estimate) based on writing. It estimates that news reporters averaged 100-120, Stephen Hawking’s last work was in the 150s, Alexander Hamilton had works in the 160s, and Qanon conspiraters on Facebook averaged 75-89. Obviously they’re estimates, but it seems rather accurate within margin.

Edit: found it!! so you guys can try it yourselves!

I entered sections from my papers I wrote during my master’s and I guess I range from 128-151 as my lowest and highest during that time. Great ego boost for the day lol.
