Kevin Kelly's Complexity Theory: The Politics and Ideology of Self-organising Systems

Regarded as a contemporary prophet of the new technology and economy, widely acclaimed author and editor of Wired , Kevin Kelly argues that the realms of nature and human construction are becoming one. Human-made things are becoming more lifelike and life is becoming more engineered. Utilising complexity theory and other concepts fashioned on the paradigmatic logic of biological systems, Kelly envisions a future with radically different forms of social and organisational control. In this future world, control is dispersed in highly pluralistic, open, and decentralised systems. Natural, technological, economic and social elements of the system co-evolve towards a superior, neo-biological civilisation that (among other things) will foster bottom-up control, co-ordinated change and co-operation among all elements. We contest Kelly's metaphysic of the new economy and new technology, arguing that he illicitly collapses technology and the economy into nature, using nature metaphors to legitimate the new forms of economy and organisation. We argue that Kelly fails to factor in the logic of capital into his scenario and does not explore the consequences of the new organisation of economy and new technology for the environment and society.     

The Dud Effect: Adding Highly Dissimilar Fillers Increases Confidence in Lineup Identifications

Recent research in decision-making has demonstrated the “dud-alternative effect”—the tendency to become more confident that a chosen response option is correct if it is surrounded by implausible response options (Windschitl & Chambers, J Exp Psychol 30:198–215, 2004). This finding may be applicable to a lineup task: The presence of duds (i.e., highly dissimilar fillers) may increase a witness’s confidence that an identified (non-dud) lineup member is the criminal. Four studies (N = 665) demonstrate that the mere presence of highly dissimilar fillers inflates witnesses’ confidence in a mistaken identification (Studies 1–4), provides evidence that this confidence inflation is due to the duds inflating the perceived similarity of the other lineup members to the criminal (Studies 2, 3), and delineates some conditions under which the effect holds (Studies 3, 4). The addition of highly dissimilar lineup members, far from being inert, as is often implicitly assumed, can bias witnesses’ confidence reports.     

Chemical enhancement of footwear impressions in urine on fabric

A range of chemical techniques were utilised for the enhancement of footwear impressions deposited on a variety of fabric types of different colours with urine as a contaminant. A semi-automated stamping device was used to deliver test impressions at a set force to minimise the variability between impressions; multiple impressions were produced and enhanced by each reagent to determine the repeatability of the enhancement. Urine samples from different donors were analysed using a spectrofluorophotometer revealing differences between individuals. Results indicated that the enhancement of footwear impressions in urine was possible using amino acid staining techniques whereas protein stains failed to achieve successful enhancement.
