Consider how news headlines are worded to capture your attention. Look at the above poll and consider which headline will most likely grab your desire to read it immediately. You can then add why the others were not as provoking to make it your first choice.
The first news I would read is the one related to the HIV cure. Maybe because I'm a doctor and because that cure would have a great impact on our society. About the other titles:
Bush cheats on wife - I would read it out of curiosity
Osama caught in Pakistan - this would be my second choice
Schwarzenegger commits suicide - tabloid news*
China announces it will become a democracy - I wouldn't believe it
The moon landing was a hoax - official proof - number three
McDonald's closing all restaurants - I don't care
Man jumps off building with Superman uniform - tabloid news*
* meaning that this just a "bombastic" title and the story inside is about a different thing or the title is out of context.
