Fact or Complete BS? Quiz
Every answer sounds fake. Half of them are real. Can you tell fact from complete BS?
Every answer sounds fake. Half of them are real. Can you tell fact from complete BS?
Research from MIT found that false claims spread six times faster than true ones on social media, and studies show people believe roughly 50% of false statements when they're presented with confidence. This quiz puts your BS detector to the ultimate test with 50 statements that all sound equally ridiculous — except half of them are completely real.
Each round presents 10 randomized questions from a pool of 50. You'll see outrageous-sounding statements about animals, history, science, geography, and more. Your job is to figure out which ones are legit and which are complete nonsense. Instant feedback after each question reveals the truth — and the explanations are half the fun.
Our brains are wired to accept information that fits our existing mental models — psychologists call this confirmation bias. Throw in the illusory truth effect (we believe things more after hearing them repeatedly) and the Dunning-Kruger effect (overconfidence in our own knowledge), and it's no wonder misinformation thrives. This quiz will sharpen your critical thinking by forcing you to question everything.
Some of the most persistent myths include: humans only use 10% of their brains (we use all of it), the Great Wall of China is visible from space (it's too narrow), goldfish have 3-second memories (they remember things for months), and we swallow 8 spiders a year in our sleep (a fabrication designed to show how easily misinformation spreads).
Fake facts spread because they tend to be more surprising and emotionally engaging than the truth. The illusory truth effect means we're more likely to believe something the more we hear it. Social media amplifies this — MIT research shows false news stories are 70% more likely to be retweeted than true ones, and they reach people six times faster.
Several cognitive biases are at play: confirmation bias (believing things that match what we already think), the anchoring effect (over-relying on the first piece of information we hear), the bandwagon effect (believing something because others do), and the availability heuristic (assuming something is true because we can easily recall examples). Awareness of these biases is the first step to beating them.
