All the people in the world could stand in New York City – Decision Science News

See on Scoop.itBounded Rationality and Beyond

Reading the internet, we learned you could fit every person on the earth within the city limits of New York City. 

We at Decision Science News like putting things into perspective. This is why we bothered putting the size of countries into perspective by comparing them to US states. (Stay tuned for our next post on this topic in which we match states to countries on the basis of both area and population. Who doesn’t want to know things like “Israel is about as big as New Jersey in both size and population”?)

Anyway, we were reading the Internet, as we sometimes do, when we came across the finding (published here and promoted here) that you could fit every person on the earth within the city limits of New York City.

And that’s assuming a flat NYC with no buildings. Considering that much of NYC is built up, you could fit them into even less space by using the advanced technology of multi-story buildings. In fact, you’ll see at the original post that everybody in the world could fit in a cube-shaped building that is just 5 crosstown blocks per side.

Are we in control of our own decisions?

See on Scoop.itBounded Rationality and Beyond

Behavioral economist Dan Ariely, the author of Predictably Irrational, uses classic visual illusions and his own counterintuitive (and sometimes shocking) research findings to show how we’re not as rational as we think when we make decisions.

When it comes to building the physical world, we kind of understand our limitations. We build steps. And we build these things that not everybody can use obviously. (Laughter) We understand our limitations,and we build around it. But for some reason when it comes to the mental world, when we design things like healthcare and retirement and stockmarkets, we somehow forget the idea that we are limited. I think that if we understood our cognitive limitations in the same way that we understand our physical limitations, even though they don’t stare us in the face in the same way, we could design a better world.And that, I think, is the hope of this thing.

On Resilient Behaviors in Computational Systems and Environments

See on Scoop.itBounded Rationality and Beyond

The present article introduces a reference framework for discussing resilience of computational systems. Rather than a property that may or may not be exhibited by a system, resilience is interpreted here as the emerging result of a dynamic process. Said process represents the dynamic interplay between the behaviors exercised by a system and those of the environment it is set to operate in. As a result of this interpretation, coherent definitions of several aspects of resilience can be derived and proposed, including elasticity, change tolerance, and antifragility. Definitions are also provided for measures of the risk of unresilience as well as for the optimal match of a given resilient design with respect to the current environmental conditions. Finally, a resilience strategy based on our model is exemplified through a simple scenario.

How equal do we want the world to be? You’d be surprised – Dan Ariely

See on Scoop.itBounded Rationality and Beyond

The news of society’s growing inequality makes all of us uneasy. But why? Dan Ariely reveals some new, surprising research on what we think is fair, as far as how wealth is distributed over societies … then shows how it stacks up to the real stats.

To summarize, I would say, next time you go to drink beer or wine, first of all, think about, what is it in your experience that is real, and what is it in your experience that is a placebo effect coming from expectations? And then think about what it also means for other decisions in your life, and hopefully also for policy questions that affect all of us.
