Why robots never click "I am not a robot"

 

 

Wouldn't a smart robot just check the box saying he's not a robot?

 

Apparently not. 

 

"This test takes into account the movement of the user's cursor as it approaches the checkbox. 

Even the most direct motion by a human has some amount of randomness on the microscopic level: tiny unconscious movements that bots can't easily mimic. 

If the cursor's movement contains some of this unpredictability, then the test decides that the user is probably legitimate. The reCAPTCHA test also may assess the cookies stored by the browser on a user device and the device's history in order to tell if the user is likely to be a bot.

 Most of the time the user's cursor movements, cookies, and device history are conclusive enough."

 

So clicking "not a robot"

allows the clearance program

to scan everything in your browser's

history? 

 

I doubt if one in 50

humans realizes that.

 The robots probably do.

 

So they don't click.
