I have noticed that some CAPTCHA pages, like Cloudflare’s, simply ask you to check a box to proceed. There is no clicking on traffic lights or entering characters. How does clicking on a check box tell them I am not a robot?

    Because it measures how your mouse moves to the checkbox. If there was nothing to move to, you wouldn’t move your mouse.

      I get the checkbox even on mobile sometimes, I imagine as long as you’re not perfectly hitting the center pixel it knows you’re human.
