The principle of an opportunity cost does not at first glance seem hard to understand. If you spend half an hour noodling around on Twitter, when you would otherwise have been reading a book, the lost book-reading time is the opportunity cost of the tweeting. If you decide to buy a fancy belt for £100 instead of a…
Facebook, Twitter, Instagram, Google have produced amazing products that have benefited the world enormously. But these companies are also caught in a zero-sum race for our finite attention, which they need to make money. Constantly forced to outperform their competitors, they must use increasingly persuasive…
What concerns me is how our information networks have enabled us to become hyper-connected to geographically distant communities, while at the same time disconnected from our local ones. Virtual and long-distance relationships can enrich our lives in myriad ways, but I fear that our reliance on them has the potential…
What a president says is typically allotted a ton of news value, by default, and rightly so. But it has been assigned news value because it traditionally has had a very high signal-to-noise ratio. Presidential remarks are normally so considered, vetted, poll-tested, etc. They usually are a somewhat reliable guide to…
1. Seek Novelty There is only one trait out of the "Big Five" from the Five Factor Model of personality (Acronym: OCEAN, or Openness, Conscientiousness, Extroversion, Agreeableness, and Neuroticism) that correlates with IQ, and it is the trait of Openness to new experience. People who rate high on Openness are…
...innovation often occurs through sequencing—building on prior innovation. Recall that suitcases didn't used to have wheels. Then someone created a suitcase with two wheels. Now many suitcases have four wheels. What helpful improvement on the suitcase might come next? I've pitched this question to students, who then…
Social networks allow people to connect with each other and have conversations on a wide variety of topics. However, users tend to connect with like-minded people and read agreeable information, a behavior that leads to group polarization. Motivated by this scenario, we study how to take advantage of partial homophily…
Now, I could tell you what these four types of strength are, but I'd rather you experience them firsthand. I'd rather we all start building them up together right now. So here's what we're going to do. We're going to play a quick game together. This is where you earn those seven and a half minutes of bonus life that I…
My professors’ generation could respond to silliness like creationism with head-scratching bemusement. My students cannot afford that luxury. Instead they must become fierce champions of science in the marketplace of ideas. During my undergraduate studies I was shocked at the low opinion some of my professors had of…
I find that the biggest barrier to a reasoned debate is time rather than space, restrictive though it may be. Everything goes so fast that there is pressure to react sooner rather than later without allowing time for reflection. People then fall back on popular "truths" that can quickly be thrown out there. You can…
I do find that smaller and smaller bits of information can command the full attention of my over-educated mind. And not just me; everyone reports succumbing to the lure of fast, tiny, interruptions of information. In response to this incessant barrage of bits, the culture of the Internet has been busy unbundling…
But sometimes I think much of what we get on the Internet is empty calories. It’s sugar — short videos, pokes from friends, blog posts, Twitter posts (even blogs seem longwinded now), pop-ups and visualizations…Sugar is so much easier to digest, so enticing…and ultimately, it leaves us hungrier than before. Worse than…
Asymmetric attention is the key to another important concept, celebrity. Being famous means that a lot of people pay attention to you--after all, by definition it is famous people who appear on the cover of magazines, which are purchased because lots of people want to know what's happening with their favorite…
