It was some random survey. It had a coin toss thing and I had to report whether it was heads or tails each time, and the whole purpose of the study was to see if I would lie about it or not. When I got to the end, I wrote in the "Do you have any comments?" box about how I thought the whole premise of their study was flawed and that they weren't going to get any useful information from it. I seriously went on with this explanation for like 10 minutes about why I thought it was all bullshit. It was a 25c survey. Oh, how young and naive I was in those days.
