Actually, I still don’t understand why xD First of all, people weren’t voting just once, people could vote twice on the last book. Voting twice would mean that people could vote on their 2 most favorite options. This would pretty much eliminate the paradox of choice in my opinion.
By not having limited options, the possibilities of the “okay” for most people winning would be bigger, compared to the 2 choices option. This would mean that more people could be satisfied by the okay result, but not that many would be excited. The author of the video assumes in his example that by voting once, the losing group automatically won’t agree with the final decision. He also assumes that everyone would see voting in the same way. Having people that voted once and others that voted 1+ times doesn’t mean that they all had the same reasoning on voting, simply because it isn’t a system people are used to.
Don’t get me wrong. In my group of friends, I always allow multiple votes when we’re planning to go out. However, in my case the goal is to have as many people available to go out as possible. In here, we’re deciding which book to read, which is a lot less rigorous. It’s not like people won’t be able to buy the book if the winner is one they didn’t vote for. Just my 2 cents. We can solve this with a poll though Seems fair.
