And the winner is….

Thanks to all the people who participated in the probabilistic promotion for “The Upside.”

The average response to “would you buy this book without this promotion was 72% (on a 100% scale), and the average response to “would you wait longer was 62% (on a 100% scale). This means that this promotion worked mainly for people who were going to buy the book anyway at some point. But, there seems to be a substantial group that would have not purchased the book without this promotion.

There were people from all over the US, and some from outside the US — and the winner that was selected at random is from Washington DC.

I hope this was fun for everyone, and if you have any other suggestions for creative promotions, let me know — I am happy to try more things.

Irrationally yours
