After doing it for real, I tried it a few more times with a cryptographically random shuffle. Interestingly, the computer got a worse score on average. Method: I started `irb`, and picked like so: require 'securerandom' # Coin flip 12.times { p [:heads, :tails].shuffle(random: SecureRandom)[0] } # Dice roll 10.times { p (1..6).to_a.shuffle(random: SecureRandom)[0] } # 10 dots 10.times { p (1..9).to_a.shuffle(random: SecureRandom)[0] } I disconnected from the internet before the scores were submitted so as not to taint the survey. (Ranking calculation happens offline based on a CSV of scores loaded into the browser early on.) Results: For: "Your answer got a higher random score than X% of people in the study." Me: 46%, 71%, 59%, 72% Computer: 32%, 20%, 47%, 31% My sample size is obviously too small for anything conclusive. However, I'll admit it makes me a little suspicious that something else is amiss.
