Explanation
The Joke
A woman presents an invention: an "entirely new way to tell bots from humans." The method works by sending a page from a tax return from three years ago. A robot will literally never attempt to comply, whereas a human will be unable to resist the urge not to comply either -- but the key difference is in timing. If an attempt to complete the form is made within 5 seconds, the user is a robot; otherwise, they are human. The core insight, she explains, is that "laziness is the biomarker for humanness." In the final panel, someone objects that this is a problem, but she says: "And all those people thought it was one too."
The Humor
The comic inverts the concept of a CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart). Traditional CAPTCHAs work by presenting tasks that are easy for humans but hard for bots, such as identifying distorted text or selecting images. The "reverse CAPTCHA" instead exploits a quintessentially human trait: laziness and procrastination. The joke is that the most reliable way to identify a human is not through superior intelligence or pattern recognition, but through the distinctly human tendency to avoid tedious bureaucratic tasks like filing taxes. A robot would either complete it instantly or not at all, but a human would groan and put it off. The humor also touches on the universal experience of procrastinating on tax paperwork.
