Take the UVa rape case. This sort of thing happens often (and definitely not just at UVa) and the perpetrators often get away with it, because they tend to come from upper-middle and upper-class backgrounds and have access to the best legal representation their parents can buy. It's disgusting. Unfortunately, the holes in this particular story are going to lead people to conclude that fraternity-house rape isn't a problem because this one case was "refuted" (even though it's not clear that it has been refuted, only that she recalled some of the details incorrectly).
The "boy genius" making $72 million is another charismatic falsehood. The underlying truth is that the upper classes aren't any smarter or more competent than the middle classes. We like being reminded of that, when a public-school student (granted, from one of the best public high schools in the world) beats the pants off the market. Sadly (?) it turns out this was achieved in simulation rather than with real money, and 'nemanja already addressed why it would be hard to pull off on the real market. Unfortunately, the rich twats who control all the social access and the jobs where one can actually have a $72M impact are going to read this story and conclude that "the poors are just dishonest".
Being somewhat of an expert on the startup career, I'm familiar as well with the aggressive use of charismatic falsehood that people have to use to advance their own careers and gain credibility/worthiness in front of investors. They concoct a story that is factually false but, as they see it, betrays an underlying truth (pertaining to their own competence). Unfortunately, if they get caught, it takes down (i.e. falsely refutes) the underlying truth along with the (usually small) lie.
