It sure is. Most analyses of perception now emphasise how the mind generates and tests hypotheses about the perceived world rather than using purely optical methods.

Probably most people have seen this. It's about perception. But if you haven't, watch it.

Steady on! We can't be having radical ideas like that!

It's a versatile video because it can demonstrate either that you're so focused on the task that you fail to notice otherwise remarkable events, or that you're so easily distracted by background events that you fail to complete the task.

Sorry. Yes, you're right, it's just crazy talk, isn't it?

Yes, basketball themed.

The interesting thing is, the first time I saw it I didn't notice the other thing. Now, even if I'm doing what the video asks you to do, I do always notice the other thing. So there's something interesting going on there. I can't make myself "unsee".

Isn't it wonderful?

And an excellent *use of analogy as a means of making us think differently. Remembering the ******* is important in so many situations.

* And quite different from the use of analogy as whataboutery.
