Well... surely, if you are wrong about something it is good to find out about that, and update your map. And surely it is a good thing to change your mind rather than defensively cling to your opinions.

But, 'winning the lottery'? Not being wrong in the first place is better (ie., having the more accurate map already is obviously better); and there is a (rational or not) social (status) cost to being shown wrong (imagine being shown wrong all the time - that's certainly not like winning the lottery all the time...)

So, while I would agree that most people are not willing enough to change their opinions when evidence comes in against them, trying to achieve that by claiming that being shown wrong is the best thing since sliced bread goes too far. Associating something desirable with something you want to promote may be good marketing of course...
