How to keep discussions with supervisor on interest? I am a Master's student. I have one problem. I have regular meetings with my research supervisor, but during the discussions he takes me in the wrong direction. This often leads to him coming to the wrong conclusions about my work.

For example, he will read half of a statement and try to conclude something (wrong) from that half statement. I try to correct him but he doesn't listen. So far I have not seen any benefits for my research. How can I deal with this situtation? I know it is research and some times we need to go in the wrong direction.
This is a partial strategy, but I realized it's more an answer than a comment. I'm sure others will have very useful strategies for this all-too-common problem.

You could phrase it as "yes, and..." rather than correcting. "Yes, that's an interesting angle: I thought about that too and then I realized X. So then I [details getting back on track.]" Not saying it'll work, but this may be a way to bring him back with you into the active part of the problem-solving space.

Also, if you can have a one page overview/agenda that previews the path you've taken, that might be easier to get him to follow along with and prevent misconceptions. Also, perhaps have two or three clear questions written at the bottom of the one-page agenda, so he gets a chance to weigh in on something new, and you get a chance to get his clear feedback on something you need to know. (Then email an update with a revised agenda attached, with "Thanks for talking about this! I've added my notes about what we talked about today, for reference.")
