I think he tries to do History Matter's schtick of answering questions you didn't think you needed answering until you saw it being asked, but with less effort. I think his deleted video on whether Trump is a fascist was probably the biggest insight into how he probably does things. He might read a single book, then try to make a video or two from a few pages within said book. Then again, I might be giving him too much credit if what you said he did is true. The Trump video certainly made me doubt the conclusions he reached in prior videos, mostly pertaining to whether the conclusions he reaches are even his to begin with. He might not even read a book, his creative process might rely entirely on thinking of the question and regurgitating what he reads on google, wikipedia, or ChatGPT. His thought process isn't his own, he just takes the thought process of the source he's citing and then passes that off as his. The source he utilised for his Trump video for example was basically just Umberto Eco but critical of Vichy France instead of Italy and is still alive, alive enough at least to go on tv and give an interview which answers the question HC asked in the title of the now deleted video: Is Maga fascist?
