Increasing Attachment and Valuation Through Touch

The endowment effect is old news: the amount that we value an object increases once we take ownership of it. The ‘extended version’ shows that the impact of the endowment effect increases with time: our valuation of an object increases more and more as the amount of time that we own it also increases. This is known as the length-of-ownership effect.

A recent study published in the journal Judgement and Decision Making1 has taken an even deeper look at this effect: studying how touching an object increases both our attachment to that object and how much we value it… even if we don’t own it (also in pdf). Here are the key findings of this ‘pre-ownership exposure study’:

  • Touching an object will increase our attachment to it and valuation of it, whether we own it or not.
  • The longer we touch or handle an un-owned object, the greater we will value it and feel attached to it.
  • Simply thinking about an un-owned object increases our valuation of it and how much we feel attached to it.

Related findings, cited in this article:

  • If an object is being sold at auction, the amount that we value the object will increase as the length of the auction increases.
  • Owning a coupon for an object increases our emotional attachment to that object.
  • Making an item the “focus of a comparison” increases its attractiveness and the probability that it would later be selected. We will also feel more attached to the item and will value it higher.

The Zeigarnik Effect and the Force of Incomplete Tasks

Why do unresolved issues linger in our mind, making us ponder them for days on end? Why are cliffhangers so successful in getting viewers to tune in to the next episode? How can we overcome procrastination? These questions can be answered by learning about the psychological concept/theory known as the Zeigarnik effect.

‘Discovered’ by Soviet psychologist Bluma Zeigarnik back in the 1920s, the Zeigarnik effect states that we remember incomplete or interrupted tasks better than completed tasks.

And so, to those questions. It’s easy to see how the Zeigarnik effect could be responsible for the success of suspense as a dramatic device, but for overcoming procrastination? Use the effect to your advantage and start at the simplest, smallest part of your task. After that, the unfinished nature of the larger task will push you toward action.

Beware, though: the effect has been shown to diminish if we don’t expect to do well on the interrupted task (or are otherwise completely not motivated).

A “Felt Need” Is What Makes Us Buy

A “felt need” is what differentiates a vitamin from an aspirin: when we crave something (relief from pain), a product that satisfies that desire becomes a must-have rather than a nice-to-have. Realising this and re-framing a product in terms of this craving is an important step in ensuring a product’s success, say Dan and Chip Heath, authors of the excellent Switch and Made to Stick.

Becoming aware of this idea is what led to the success of Netflix and NetApp… as well as the demise of countless other companies. In a brief article describing how re-framing a nice-to-have product as a must-have is all about discovering and exploiting a specific “felt need”, the Heaths look at Ray Bards failed attempt at getting his “vitamin” book published and how realizing this idea of a felt need led him to become a successful publisher.

If entrepreneurs want to succeed […] they’d better be selling aspirin rather than vitamins. Vitamins are nice; they’re healthy. But aspirin cures your pain; it’s not a nice-to-have, it’s a must-have. […]

That aspirin quality is what Bard now looks for in a book. He says that successful books address a deep “felt need” — that is, readers hunger for the answers the book provides. Classic examples would be diet books, personal-finance books, and books that promise you mega success if you’ll just radiate positive energy to the universe, indicating your receptivity to mega success. Bard has become a talented diviner of felt need. Fully half of the books that he publishes become best sellers. […]

You’ve heard the old saying “If you invent a better mousetrap, the world will beat a path to your door.” Don’t bet on it. The world’s felt need isn’t for a better mousetrap. It’s for a dead mouse. […]

When engineers or marketers or entrepreneurs get too close to their products, it’s easy to mistake a vitamin for an aspirin. If your team is flirting with delusion, a little love might point you in the right direction.

How Trends Actually Spread; or, Six Degrees but No Connectors

The small sample size of Stanley Milgram’s small world experiment means that the theory of ‘six degrees of separation’ and the conclusion drawn from it–primarily, the Influential’s theory popularised by Malcolm Gladwell in The Tipping Point–could be deeply flawed. That was the starting point for Duncan Watts‘ research that led him to say “the Tipping Point is toast”.

So to research how ideas and trends spread virally, Watts (who is author of Everything is Obvious, principal research scientist at Yahoo! Research (he directs their Human Social Dynamics group), and founding director of Columbia University’s Collective Dynamics Group) ran large-scale reproductions of the small world experiment and hundreds of computer simulations that brought forward two conclusions: the six degrees of separation theory is correct, but there is no evidence for super-connected ‘trend gatekeepers’ (such as Gladwell’s ‘Connectors’):

But Watts, for one, didn’t think the gatekeeper model was true. It certainly didn’t match what he’d found studying networks. So he decided to test it in the real world by remounting the Milgram experiment on a massive scale. In 2001, Watts used a Web site to recruit about 61,000 people, then asked them to ferry messages to 18 targets worldwide. Sure enough, he found that Milgram was right: The average length of the chain was roughly six links. But when he examined these pathways, he found that “hubs”–highly connected people–weren’t crucial. Sure, they existed. But only 5% of the email messages passed through one of these superconnectors. The rest of the messages moved through society in much more democratic paths, zipping from one weakly connected individual to another, until they arrived at the target. […]

[His computer simulation] results were deeply counterintuitive. The experiment did produce several hundred societywide infections. But in the large majority of cases, the cascade began with an average Joe (although in cases where an Influential touched off the trend, it spread much further). To stack the deck in favor of Influentials, Watts changed the simulation, making them 10 times more connected. Now they could infect 40 times more people than the average citizen (and again, when they kicked off a cascade, it was substantially larger). But the rank-and-file citizen was still far more likely to start a contagion.

I can’t help but find it somewhat ironic that, written almost four years ago, this argument hasn’t really gained much traction and Gladwell’s ideas are still discussed ad nauseam.

Inventive Ways to Control Trolls

To keep the peace on the ever-expanding Stack Exchange Network of online communities, owners Joel Spolsky and Jeff Atwood introduced the timed suspension of disruptive users’ accounts. Over time the transparency of the timed suspension process proved to be occasionally inefficient when discussions arose regarding the merits of certain suspensions. This led the administrators of the communities to investigate other ways of moderating problematic users.

What they found were three fantastically devious secret ways to effectively control trolls and other abusive users on online communities: the hellban, slowban, and errorban:

A hellbanned user is invisible to all other users, but crucially, not himself. From their perspective, they are participating normally in the community but nobody ever responds to them. They can no longer disrupt the community because they are effectively a ghost. It’s a clever way of enforcing the “don’t feed the troll” rule in the community. When nothing they post ever gets a response, a hellbanned user is likely to get bored or frustrated and leave. I believe it, too; if I learned anything from reading The Great Brain as a child, it’s that the silent treatment is the cruelest punishment of them all. […]

(There is one additional form of hellbanning that I feel compelled to mention because it is particularly cruel – when hellbanned users can see only themselves and other hellbanned users. Brrr. I’m pretty sure Dante wrote a chapter about that, somewhere.)

A slowbanned user has delays forcibly introduced into every page they visit. From their perspective, your site has just gotten terribly, horribly slow. And stays that way. They can hardly disrupt the community when they’re struggling to get web pages to load. There’s also science behind this one, because per research from Google and Amazon, every page load delay directly reduces participation. Get slow enough, for long enough, and a slowbanned user is likely to seek out greener and speedier pastures elsewhere on the internet.

An errorbanned user has errors inserted at random into pages they visit. You might consider this a more severe extension of slowbanning – instead of pages loading slowly, they might not load at all, return cryptic HTTP errors, return the wrong page altogether, fail to load key dependencies like JavaScript and images and CSS, and so forth. I’m sure your devious little brains can imagine dozens of ways things could go “wrong” for an errorbanned user. This one is a bit more esoteric, but it isn’t theoretical; an existing implementation exists in the form of the Drupal Misery module.
