How Movie Effects Fool Your Brain

In this funny 15-minute TED Talk, special effects guru Rob Legato explains, shot by shot, how he made visual effects work in Apollo 13, Titanic, and Hugo. In addition to making great models, he did it by observing what people noticed versus what they saw. A sample quote regarding the Saturn V launch he recreated for Apollo 13: "[The shot was about] what they remembered it looked like -- but not what it really looked like." Legato's message here is relevant for any kind of artist: it's more important to know what your audiences feels they have seen (or read, or listened to), not what actually happened.

Also: "Once you believe something is real, you transfer everything that you feel about it -- this [real] quality you have -- and it's totally artificial, it's totally make-believe, yet it's not to you." -On making model shots in a garage for Titanic, mixed seamlessly with real shots from James Cameron's undersea cameras shooting the real Titanic.

This is terrific stuff -- a smart discussion of how human vision and emotions relate. This guy can do my DVD extras any day.

My favorite laugh line: "I'm the guy out in the parking lot, recreating one of America's finest moments with fire extinguishers." -Legato to a NASA astronaut, upon being told Legato's science is wrong.

Alternately, the TED.com version has captions.

What Pop Culture Gets Wrong About Dissociative Identity Disorder

From the characters in Fight Club to Dr. Jekyll and Mr. Hyde, popular culture is filled with "split" personalities. These dramatic figures might be entertaining, but they're rarely (if ever) scientifically accurate, SciShow Psych's Hank Green explains in the channel's latest video. Most representations contribute to a collective misunderstanding of dissociative identity disorder, or DID, which was once known as multiple personality disorder.

Experts often disagree about DID's diagnostic criteria, what causes it, and in some cases, whether it exists at all. Many, however, agree that people with DID don't have multiple figures living inside their heads, all clamoring to take over their body at a moment's notice. Those with DID do have fragmented personalities, which can cause lapses of memory, psychological distress, and impaired daily function, among other side effects.

Learn more about DID (and what the media gets wrong about mental illness) by watching the video below.

Humblebraggarts Are the Worst (Science Says So)

Humblebraggarts. We all know (at least) one: that person who takes a woe-is-me tack to ostensibly "complain" about something when the real intent is to boast.

"It's noon, I haven't had a cup of coffee, and the espresso machine at this Mercedes dealer is broken. FML!"

"Have been sitting on the runway for 30 minutes. Next time I'm flying commercial instead of private."

In many ways, it's another version of #FirstWorldProblems, and social media outlets like Facebook, Instagram, and Twitter have only made the practice more pervasive. As TIME reports, a new study has concluded that people see right through this fake humility—and like people less for doing it.

Researchers at Harvard and the University of North Carolina at Chapel Hill conducted a series of nine experiments, including a week-long diary study and a field experiment, to both identify the ubiquity of the behavior and then determine its effectiveness as a form of self-presentation. Their findings, which were published in the January Journal of Personality and Social Psychology, determined that if you're going to brag, people would rather you just be transparent about it.

"It's such a common phenomenon," Ovul Sezer, study co-author and an assistant professor of organizational behavior at UNC's Kenan-Flagler Business School, told TIME. "All of us know some people in our lives, whether in social media or in the workplace, who do this annoying thing. You think, as the humblebragger, that it's the best of both worlds, but what we show is that sincerity is actually the key ingredient."

Of the 646 participants, 70 percent of them could recall a recent humblebrag they'd heard—the majority of which (about 60 percent) were complaint-based. But the study showed, overwhelmingly, that any statements that could be perceived as humblebragging (whether complaint- or humility-based) "are less effective than straightforward bragging, as they reduce liking, perceived competence, compliance with requests, and financial generosity," according to the study's authors.

"Despite the belief that combining bragging with complaining or humility confers the benefits of each strategy," the study concluded, "we find that humblebragging confers the benefits of neither, instead backfiring because it is seen as insincere.”

In other words: they're not fooling anyone.

"If you want to announce something, go with the brag and at least own your self-promotion and reap the rewards of being sincere, rather than losing in all dimensions," Sezer said—though she suggested that an even more effective tactic is to find someone else to boast on your behalf. "If someone brags for you, that's the best thing that can happen to you, because then you don't seem like you're bragging," she told TIME.

However, Sezer's final piece of advice was not to be too hasty in your dismissal of humblebraggarts as a whole. "We all do it, to some extent," she said. "I hope I don't sound like I'm humblebragging when I talk about this research."
