A friend tried a math trick on the rest of us. We're supposed to think of a 2-digit number between 50 and 100. Then he added that both digits have to be even numbers. After we mentally re-adjusted for this, he claimed he knew what number everyone was thinking, and the answer is 68. Huh? It seemed that the majority of the people would think of that number, but actually only one of us was thinking it. In fact, 2 of us were thinking the number 88 cos that meant prosperity.

Then another friend chipped in with another mind trick. We're supposed to keep thinking the number 6, and then we're asked to think of a vegetable that starts with the letter 'C'. Most people should respond with 'carrot', but I thought 'cabbage' instead and another friend thought 'celery'. Hmm.

Maybe cultural biaseness should be included in experiments like these.
