Check to see if Google know's who you are

Google's new reCAPTCHA will not show a captcha if they know how you are.

Thanks Google for this new tool to check if your anonymous.

If you see a captcha then Google is not sure who you are.

If you see a check box and text "I am not a robot" then Google has you tracked.

I'm logged into gmail and see the captcha in another tab regardless. Perhaps because I refuse 3rd party cookies but never-the-less it pokes a hole in your theory.

What are you using to block 3rd party cookies? Maybe that blocked cookies or script on the captcha page that triggered a flag to ask for captcha.

Firefox's "Block 3rd party cookies" setting

I see "I am not a robot" but when I click on it I get a Captcha. So??
