PALO ALTO, CA – A groundbreaking new study published this week has officially declared that the most accurate and efficient method for determining an individual's 'brain age' is, in fact, a series of online trick questions. The findings, which surprised absolutely no one who has ever spent an afternoon procrastinating, suggest that traditional neurological diagnostics are now largely obsolete.

“We’ve been doing it all wrong,” stated Dr. Evelyn Reed, lead researcher and self-proclaimed 'quiz enthusiast' from the Institute of Cognitive Whimsy. “Turns out, asking someone to pick the odd one out from a series of emojis or identify which celebrity wore it better provides a far more nuanced understanding of their neural pathways than, say, an MRI or a comprehensive neuropsychological evaluation. It’s just… faster.”

The study, which involved hundreds of participants and an undisclosed number of animated GIFs, concluded that the average person's brain age could swing wildly depending on their last meal, current Wi-Fi speed, or whether they’d remembered to charge their phone. “It’s a dynamic metric,” Dr. Reed explained, “much like your mood after seeing a particularly cute puppy video.”

Industry experts are already predicting a seismic shift in healthcare, with clinics reportedly replacing expensive diagnostic equipment with a single tablet running a popular quiz platform. Insurance companies are said to be thrilled, eagerly anticipating the cost savings from replacing complex medical procedures with a simple 'Are you more of a cat person or a dog person?' assessment. Critics, however, warn that this could lead to a generation whose cognitive health is determined by their ability to spot a poorly photoshopped image.

Future research is expected to determine if BuzzFeed quizzes can also diagnose appendicitis.
