Legion, you're not alone. The first time I heard the puzzle it took me quite a while to understand why it paid to switch.
A lot of people describe Scalzi’s Old Man's War novels as military science fiction, but I would classify its sequel Zoë’s Tale as a space opera. It’s a story about, well, Zoë, a teenage girl whose parents are invited to take leadership roles in building a colony on a new planet. Zoë is an enthusiastic member of the group sent to colonize Roanoke, despite the risks—and the risks are considerable even before the political machinations of greater powers boil to the surface.

You and two other very smart people were brought before the President. He want's to see which of you is the smartest, so you can figure out how to lower gas prices.
You are led blind-folded into a small room, and seated around a table. The president describes the test.
"Upon each of your heads I have placed a hat. You are either wearing a blue hat or a white hat. You don't know which, but I will tell you this; at least one of you is wearing a blue hat. There may be only one blue hat and two white hats, there may be two blue hats and one white hat, or there may be three blue hats. But you may be certain that there are not three white hats."
The president explains that when the blindfolds are taken off, the first to correctly announce the color of his hat shall be his advisor.
With that, the president uncovers your eyes and you see that your two competitors are each wearing blue hats. You see from the look in their eyes that they are thinking, "What is the color of my hat?"
For hours nobody speaks, then finally you stand up and say, "The color of the hat I am wearing is..."
What color is your hat? And how do you come to that conclusiong?
This does not chance the fact that the question still leaves you with only 2 choices.
Formula is now
A = still your pick
B=another box
C = been eliminated so its zero now
A + (B + 0) = 100% chance of winning...is that right?
So then it's really A + B = 100% chance of winning...2 choices both equal it’s a 50/50 chance that either is true...
Can you show me anything that is wrong with this logic?
I'm sorry, we can't have two Eric's here, it's far too confusing.
