Can you pass the World's Shortest IQ Test? It's only 3 questions! Developed at MIT, it shows how vulnerable you are to many cognitive biases and more than 80% fail! including more than half of MIT students! Here's the first question. A bat and a ball cost $1.10 in total. The bat costs $1 more than the ball. How much does the ball cost? Pause and think. Write down your answer. Next question in... 4 3 2 1 Here's the second question. If it takes 5 machines 5 minutes to make 5 widgets, How long would it take 100 machines to make 100 widgets? Whatever a widget is. Pause and think. Write down your answer. Next question in... 5 4 3 2 1 Here's the third and last question. In a lake there is a patch of lilypads Every day the patch doubles in size If it takes 48 days for the patch to cover the entire lake How long does it take to cover half the lake? DON'T CHEAT! Think, then write your answer in the comments. Along with how hard you found the question on a scale from 1-10 I'll explain why later! You'll like it! In my next video i'll explain why these questions are deceptively hard. And what your answers say about you.
