Except by answering captchas, you're helping the machines (first words for books, then numbers for street view, now pictures for classification).

That's an interesting thought that every time we introduce novel classification schemes to resolve humans from computers we feed a large training set for them. I never understood how that works, though. If I get a captcha street address wrong then that means they already had the answer, so how am I contributing?

For the street address ones you generally have to answer two questions, one that they know and one that they don't know. You're only 'tested' on one of them, but you don't know which. Once enough people have gotten the known one right and given the same answer to the unknown image they move the unknown image to the known pile.

On what page did you tested the new system?

Here you go: https://www.google.com/recaptcha/api2/demo

1. Tested on my normal chrome where I didn't delete any cookies and logged in to my google accounts, and no adblocker running. So plenty of evidence I'm human, with all those cookies from big G.

2. Tested in incognito mode: BAAM: I'm a bot, had to fill out the old captcha!

I can't think of many better uses for the menagerie of different tracking methods that they have planted on me, to be honest.

Well if you ever run for political office it's going to save them a boatload on campaign contributions.

Eh, you never know. Attitudes toward certain improprieties have moderated in recent years...

Do they even need the checkbox anymore? They could track mouse movement, keypresses, history or whatever else they are tracking without showing any kind of GUI at all.

Or add the mouse tracking checks to a button that is naturally part of the website, such as "Post Comment" on a WordPress blog.

They already know the correct answer if they are only showing you one image to solve.

When there are two images to solve, they know the correct answer to one. The other is shown to thousands of people, and eventually it is solved with high confidence.

I wish these google pages wouldn't automatically assume you speak some language based on your IP address - I get mine in German without any option to switch. Aren't there standards for setting language in web browsers?

Your browser sends an "Accept-Language" header with the list of languages and order of preference you have configured.

Sure, but many sites including Google like to ignore these (or at least have done so in the past).

The rationalisation is that users don't change settings like these, so their location is a better indicator than what their browser thinks.
