I’m not sure I understand what I’m looking at but I think my reading is that if people are unsure about quitting their jobs they probably just need a bit of kick out of status-quo bias, but if people are unsure about whether or not they should propose, they should probably find something they are more sure about instead of letting a coin decide. It doesn’t sound totally unintuitive to me. I guess I think of people thinking about quitting as being biased towards the status quo and I think of people who propose as being indecisive about the timing/method but having reasonable conviction about wanting to do it, so I guess that the people having reservations and being indecisive have genuine reservations?

Also, based on the GP’s formula, maybe the effects look large because people don’t do what the coin tells them very often so you are dividing by a small number?
