I was trying to pick one of four books to take with me to the doctor's office, and asked one of my coworkers to pick a number 1-4. He chose three, and I told him that was the most likely answer for him to give. He asked why, and I explained that people tended to pick numbers centered around 3/4 of the range, with a secondary cluster around 1/4 of the range.
So I posted a poll to "prove" it. Even knowing that my friends were more likely than average to be aware of this, and/or to randomize, I predicted that both the mean and the median would be above 5.5.
The mean was 5.97, and the median was 7. Y'all are surprisingly typical, I think.
