Having heard radio interviews with and without 'internal editing' to remove ums and ahs, most of the time I'd rather the edited version. It's more concise and focused, and I find it easier to comprehend. Too many ums and ahs and my mind wanders, and if it's radio, I can't go easily go back to try again. When I've listened to podcasts or audiobooks, I could never easily go back a little to try again either, and I gave up on them (even though I have some content I really want to listen to, it's too frustrating, so it's not happening). But I'm sure other people have different preferences.

I also don't care for writing that could have been made a lot more concise. It's a lot of work to make things shorter, but I think it's worthwhile.

It just goes to show that people have very different views. I think when I hear people thinking out loud (ums and ahs) it's a marker that they are actually engaging with the question, thinking through an answer and not bullshitting without thinking.
