What is Complexity Theory? – Kieran D. Kelly

See on Scoop.itBounded Rationality and Beyond

Spontaneous Order & Complexity does not arise in defiance of The Second Law of Thermodynamics but with the help of it!… Complexity is Coarse Entropy!…

Complexity arises from the ubiquitous “Interplay of Symmetry-Breaking and Entropy” in driven-damped systems — Emergent Complexity is a form of “Coarse Damping”!

Damping is a term used in engineering to describe the elimination unwanted vibrations and fluctuations in a system.  Damping usually involves the external dissipation of excessive energy.

Complexity however is not about the external dissipation energy; on the contrary it is about the internal distribution of energy.  Complexity is about the internal dissymmetry/imbalance of parts, within a system, which pulls the system as a whole spontaneously to a “complex structural equilibrium”.  Complexity is a “Coarse” form of damping to“thermal equilibrium”.  Complexity is Coarse Uniformity!  Complexity is Coarse Symmetry!

Fresh insights counter voter apathy

See on Scoop.itBounded Rationality and Beyond

Sometimes a short advert or article can really bring home the need to act in a way that no amount of lecturing or blanket coverage can.

While watching some re-runs of the Big Bang Theory this past weekend on E4 I noticed an interesting advert during the ad break…
yes I am actually one of those people who pays attention to the adverts rather than leaving the room, and it usually just means that I can pay that little bit more attention to my knitting to check I didn’t make any mistakes, but I digress… So this advert came on the screen saying that E4 will go off air on 7th May, so that we’re not too distracted by the TV to turn up to vote. It essentially said that “since there is no telly to watch on the 7th you may as well go and vote”.

The impact of business regulatory reforms on economic growth

See on Scoop.itBounded Rationality and Beyond

I investigate the link between business regulatory reforms and economic growth in 172 countries. I create a 5 year dataset on business regulatory reforms from the World Bank’s Doing Business reports. Then, I test the hypothesis that business

Basic Images for the Brain Science of Conscious Cognition. (BJ Baars)

See on Scoop.itBounded Rationality and Beyond

Cognitive neuroscience has built up a solid scientific literature since about 1990, especially due to revolutionary advances in brain recording techniques, and clarification of the kinds of experimental techniques that bear directly on conscious

Does Facebook drive political polarization? Data science and research – Journalist’s Resource

See on Scoop.itBounded Rationality and Beyond

Questions about how social media platforms may drive users into “filter bubbles” — increasingly like-minded communities whose views are reinforced and become more extreme — have been swirling for several years now. As the debate has developed in popular discourse, scholars and data scientists have continued to make insights on what is often referred to in the academic literature as online “homophily,” or colloquially as the “birds of a feather flock together” phenomenon.

In 2013, researchers at Carnegie Mellon University, Stanford and Microsoft Research analyzed anonymized browsing data from more than 1.2 million Web users and concluded that fears over an increasingly personalized Internet could be overblown: Only a “relatively small amount of online news consumption is driven by the more polarized channels, social and search, and opinion pieces — which are typically the focus of laboratory studies — constitute just 6% of consumption relating to world or national news…. [W]e find that individuals typically consume descriptive reporting, and do so by directly visiting a handful of their preferred news outlets.” Further, while social channels and search can lead to “higher segregation” and filter bubbles, those methods of news discovery can also be “associated with higher exposure to opposing perspectives, in contrast to filter-bubble fears.”
