I fear what too many people did with me (and with Deutsch and many others) is try to agree instead of giving critical feedback. I think a lot of responses are polarized between trying to agree or being broadly argumentative, and more mixed or nuanced responses are less common.
So I shared some stuff trying to get critical feedback and thought it had been exposed to people’s critical thinking when it hadn’t and they were just trying to learn it and agree with it even though it was tentative stuff I wanted to explore not teach. This came up with repeating things Deutsch told me (which, even if he believed them for many years with confidence, I still wanted to expose to critical scrutiny) and with some early-stages ideas of my own.
The argumentative people often don’t give good criticism either even when there are better arguments available on their side, which they don’t know about, don’t like, or don’t use for other reasons. So winning arguments with some people and getting praise from others doesn’t mean the ideas have been exposed to very good critical thinking even if everyone says they’re Popperians who did critical thinking.
Lots of people withhold intuitive, practical, or experience-based criticisms/disagreements/counter-examples when they are trying to be clever intellectuals and use logical philosophical arguments.
