Arbitrarily forcing a choice to clarify your feelings on the matter can actually be very useful, it’s just a bit rude to use other people for it. When I have a choice like this I’ll sometimes throw some dice (d6, 1-3 for white, 4-6 for blue), if I’m happy or don’t mind what they landed on then it’s the correct choice, if I’m not I’ll probably realize which option I was secretly hoping for was and go with that.
This is a real life hack. I’ll flip a coin to make a decision all the time, not because I’m beholden to the coin’s result, but because while the coin is spinning I’m suddenly aware of which side I hope it lands on.
