Uhm, not sure where I lie on this scale I guess. Is this the real scale or some abstract representation? Personally it's a 1 or 2 for me, but the image constantly changes and is never quite stable. There can be quite some detail, but it's only very temporary. Once I focus on some other part of the apple and go back everything is different

Up to 1 with effort. My fiancee is a 5, which if I hadn't already known beforehand that that's even possible, I would have been surprised to learn.

I'm a 1 but the apple would be morphing into different types and then the image would zoom in on patterns or what the bottom looks like etc. It would then shift to something totally unrelated like Sonic the Hedgehog. Why him? Your guess is as good as mine. There's a lot going on up there and it's noisy and constantly under construction.

To your question though, of course I don't watch them, I skip around to the good parts.

The term you are looking for is aphantasia.

Yes. Just because I can imagine a book brought to life doesn't mean I don't like watching movies.

I'm a 1 and yes. That part of my brain has a direct line to the input somehow, and can't be fooled by a mere mind-picture.

I'm interested in how women would answer, because men seem to be way more sexually visual, and women more conceptual, even across orientations.

Not so much these days. I have a lot of neglected home projects that I need to get done. Can't imagine how 3 and 4s are handling things these days.

1 or 2 I guess? Also what’s wrong with watching adult videos?

At a 2, I have but don't regularly.

I'm a 5 on this scale, but to throw a wrench in your theory, I really enjoy reading porn (books in general, really) even though I can't visualise anything.

1, I do. The imagination isn’t a perfect replacement for everything, and I find visualising things far harder to do if I’m actively forcing myself to do it (listening to music or just letting my mind wander is far better for me, so this test is pretty difficult for me since I have to force myself to focus on the apple).
