Nope. Experience with social media shows that this is Empirically untrue. There is also boat loads of research showing that just seeing false headlines results in people using that information to make decisions - even if they KNOW the headline was retracted. You can debunk whatever you like, but at that pace of information flow today, this is essentially pissing into the wind.

Our brains have some easily hackable ways to verify content.
