Collaboration is not “soft”

See on Scoop.itBounded Rationality and Beyond

I am occasionally left a little baffled by some of the stuff I read about digital social tools. In a lot of what I read and hear, there is no lack of intelligent analysis about social tools and their potential usefulness, however I do think that there is a huge dimension that is just absent.  That is the “social” bit.  I know, I know…. I only bring my understanding of what it means for human beings to be social from my own trajectory in life.  Sadly (or maybe not) in an increasingly technological world, that trajectory has not had a huge technological dimension to it.  I happily use digital social tools regularly and have learnt how they can assist me to connect and collaborate with others.  I also sometimes struggle with having to learn how to interface with the machine, often frustrated at why it doesn’t interface with me, but that’s another conversation.  When I ponder on the usefulness or otherwise of digital social tools, with relation to collaboration, my brain whirs and comes to the conclusion that it’s much less about the technical features or ubiquity or ease of use of digital social tools, and more about the users of the tools.

Jim Rickards: China wants gold so it can share market-rigging power | Gold Anti-Trust Action Committee

See on Scoop.itGold and What Moves it.

In the latest edition of his newsletter, Strategic Intelligence, James G. Rickards elaborates on a point often made by your secretary/treasurer, as last week in an interview with Dave Kranzler and Rory Hall on their “Shadow of Truth” program:

http://www.gata.org/node/15341

That is, China is not acquiring gold because it wants to liberate the currency markets from rigging by Western central banks or because it wants to impose on itself the restraint of a gold standard but because it wants its own power to rig the currency markets.

Rickards writes: “China wants to do what the United States has done, which is to remain on a paper currency standard but make that currency important enough in world finance and trade to give China leverage over the behavior of other countries.

Hal’s insight:

Imperfect Cognitions: Refining our Understanding of Choice Blindness

See on Scoop.itBrain Tricks: Belief, Bias, and Blindspots

This post is by Robert Davies, a PhD student at the University of York. Robert is interested in self-knowledge and memory, and particularly how the study of memory can shed light on philosophical problems in self-knowledge. 

Here is one variety of introspective failure: I make a choice but, when providing reasons, I offer reasons that could not be my reasons for that choice. Choice Blindness research by Lars Hall, Petter Johansson, and their colleagues (2005–) suggests it is surprisingly prevalent (see e.g. Johansson et al. 2008), showing a low rate of manipulation detection and a high degree of willingness, in non-clinical participants, to offer confabulatory explanations for manipulated choices across a range of modalities and environments (see e.g. Hall et al. 2006; Hall et al. 2010).

We see ourselves as introspectively competent, rational decision-makers—capable of knowing our reasons, weighing them as reasons, and self-regulating when required—but since widespread confabulation seems at odds with this, some reconciliation with the data is required.

The general equilibrium theory as economic metatheory

See on Scoop.itBounded Rationality and Beyond

http://www.rep.org.br/PDF/139-6.PDF
Many economists show certain nonconformity relative to the excessive mathematical 
formalization of economics. This stems from dissatisfaction with the old debate 
about the lack of correspondence between mainstream theoretical models and 
reality. Although we do not propose to settle this debate here, this article seeks to 
associate the mismatch of mathematized models with the reality of the adoption of 
the hypothetical-deductive method as reproduced by general equilibrium. We begin 
by defining the main benefits of the mathematization of economics. Secondly, we address 
traditional criticism leveled against it. We then focus on more recent criticism 
from Gillies (2005) and Bresser-Pereira (2008). Finally, we attempt to associate the 
reproduction of the hypothetical-deductive method with a metatheoretical process 
triggered by Debreu’s general equilibrium theory. In this respect, we appropriate the 
ideas of Weintraub (2002), Punzo (1991), and mainly Woo (1986) to support our 
hypothesis.
