Taking a look back at the book, I think you're right. They are misrepresenting him in this one quote. He was referring to the gross mindset he was trying out.

Taking a look back at the book, I think you're right. They are misrepresenting him in this one quote. He was referring to the gross mindset he was trying out. On the other hand, I'm in one of the departments Feynman had an appointment with for a few years. Some of the older faculty overlapped with him and have fun stories to share. However, one of the lasting memories of his stay was how he was predatory towards the undergraduate women. In fact, it was to the point that some people speculate that he was forced to the leave the department after sleeping with too many of his students. I still look up to Feynman for his science, but there were some real problems with how he treated women. Even if the article didn't do a great job of presenting the evidence for it. Besides Surely you're Joking is Feynman as portrayed by Feynman. He's famously a showman and isn't going to create an image of himself in the book that he doesn't think is likeable. Interestingly, from what I remember reading, he also did a lot to support the female scientists in his life including his sister.
