Rory Sutherland on Perceived Value

Rory Sutherland is one of my favorite TED Talkers (ahem, "Speakers"). He's a former advertising executive who is concerned with psychology -- specifically, how people perceive what is valuable, and how that perception can actually become tangible value. This makes for some interesting quotations, like from this talk: “Where economists make the fundamental mistake is they think that money is money.” Sutherland is talking about how it matters to us where the money we spend is going: if we spend money thinking it's going to good people doing good work, we're more willing to part with it than if we think it's going to incompetent buffoons. And he's right.

In this eighteen-minute talk, Sutherland leads us through a series of examples in "re-framing" situations. Some of these are simple and obvious, like the observation that retired people are, as a group, happier than unemployed young people -- despite similar circumstances (not much money and not much to do all day), retired people are generally retired on purpose. Their frame of reference is different, so their experience of life is different. Some of Sutherland's examples are much more subtle, like his observation that a main reason Google initially succeeded at being a search engine was because it just did search, rather than take the "portal" approach all other Internet companies tried. (And people like single-purpose services; we think companies tend to be best at doing one thing well.) Frankly I think there's something to that, and his point is further proved by Google's current attempt to do "everything" and its growing creepiness.

For: anyone interested in how we think, or looking for a few interesting anecdotes. (For example, apparently South Korean red lights have a countdown timer, which has been shown to reduce traffic accidents and incidents of road rage -- when you know how much longer you have to wait, the waiting is less painful.)

Language alert: Sutherland drops a single f-bomb around 1:20. I think it's hilarious, but your mileage may vary.

The Simple Optical Illusion That Makes an Image Look Like It's Drawing Itself

Artist James Nolan Gandy invents robot arms that sketch intricate mathematical shapes with pen and paper. When viewed in real time, the effect is impressive. But it becomes even more so when the videos are sped up in a timelapse. If you look closely in the video below, the illustration appears to materialize faster than the robot can put the design to paper. Gizmodo recently explained how the illusion works to make it look like parts of the sketch are forming before the machine has time to draw them.

The optical illusion isn’t an example of tricky image editing: It’s the result of something called the wagon wheel effect. You can observe this in a car wheel accelerating down the highway or in propeller blades lifting up a helicopter. If an object makes enough rotations per second, it can appear to slow down, move backwards, or even stand still.

This is especially apparent on film. Every “moving image” we see on a screen is an illusion caused by the brain filling in the gaps between a sequence of still images. In the case of the timelapse video below, the camera captured the right amount of images, in the right order, to depict the pen as moving more slowly than it did in real life. But unlike the pen, the drawing formed throughout the video isn't subject to the wagon-wheel effect, so it still appears to move at full speed. This difference makes it look like the sketch is drawing itself, no pen required.

Gandy frequently shares behind-the-scenes videos of his mechanical art on his Instagram page. You can check out some of his non-timelapse clips like the one below to better understand how his machines work, then visit his website to browse and purchase the art made by his 'bots.

And if you think his stuff is impressive, make sure to explore some of the incredible art robots have made in the past.

Narcissists Are More Likely to Be Compulsive Facebook Users

Updating your Facebook status throughout the day is probably a sign you need a different hobby, but according to a new study, the habit can also indicate something else. As PsyPost reports, people with Facebook addiction are also likely to be narcissists.

For their recent study published in the journal PLOS One, scientists from Ruhr-Universität Bochum in Germany followed the Facebook activity of 179 German students over the course of a year. They were looking for cases of so-called Facebook Addiction Disorder (FAD) based on the Bergen Facebook Addiction Scale, a system developed by University of Bergen researchers that measures factors like mood modification, withdrawal, and relapse in relation to Facebook use.

They wanted to find out whether FAD was linked to other mental health problems. In addition to gauging Facebook compulsion, they also surveyed subjects on their depression and anxiety levels, social support systems, physical health, narcissism, and general satisfaction with life. The results showed a strong correlation between FAD and narcissism. Rather than Facebook making its users more narcissistic, the researchers state that people with narcissistic personalities are at a greater risk of developing the social media addiction.

"Facebook use holds a particular meaning for narcissistic people," they write in the paper. "On Facebook, they can quickly initiate many superficial relationships with new Facebook-friends and get a large audience for their well-planned self-presentation. The more Facebook-friends they have, the higher is the possibility that they attain the popularity and admiration they are seeking; whereas in the offline world they might not be as popular since their interaction partners can quickly perceive their low agreeableness and exaggerated sense of self-importance."

The researchers also found a connection between Facebook addiction and higher levels of stress, depression, and anxiety.

Studies investigating Facebook Addiction Disorder have been conducted in the past, but there’s still not enough research to classify it as an official behavioral addiction. The researchers hope their work will lead to similar studies pinning down a link between FAD and mental health consequences.
