I was going to pick seven as well. Personal guess for why it’s a favorite... 1. I want to signal that I’m creative. If you say “random, between 1-10” picking 5 feels amateur. 2. You said “between 1-10”, which is inclusive of 1 and 10, but you positioned me to not choose the poles with the word “between.” 3. It feels random to iterate through options and settle on one. I iterate by counting up. Since 5 is out, that leaves 6,7,8,9 in my big pile’o’random. From there, for whatever reason 7 tends to stand out. Crazy how predictable we are.
