That's interesting! Although I haven't invested any thought in it, I would've assumed that announcing plans would have the opposite effect because people are now watching and know what you're trying to achieve, so you'd be more motivated to avoid losing face. Thanks for the article — I'll have to check it out!
Personally, it would make me feel a burden of shame to have announced a goal and then had a setback, which would become a greater discouragement then just facing a setback if I had not made a big deal about it in the first place.
