Three Models of Democratic Expertise

How can expertise best be integrated within democratic systems? And how can such systems best enable lay judgment of expert claims? These questions are obscured by the common framing of democratic politics against an imagined system of pure and unmixed expert rule or ‘epistocracy’. Drawing on emerging research that attempts to think critically and institutionally about expertise, this reflections essay distinguishes three ways of democratically organising relations between experts and non-experts: representative expertise, in which experts are taken to exercise limited and delegated power under the supervision of political representatives; participatory expertise, in which expertise is integrated with publics by means of directly participatory processes; and associative expertise, in which civil society groups, advocacy organisations, and social movements organise expert knowledge around the objectives of a self-organised association. Comparing these models according to the cognitive demands they make on lay citizens, the epistemic value of citizen contributions, and the ways in which they enable public scrutiny and contestation, the essay goes on to explore how they can support and undermine one another, and how they can open up new questions about democracy, trust and expertise in political science and political theory

Policymaking During Crises : How Diversity and Disagreement Can Help Manage the Politics of Expert Advice

Political leaders drawing on expertise in a crisis face two temptations: one is to dismiss unwelcome expert claims as politically motivated; another is to mask expert disagreement altogether. We show that protecting and promoting open disagreement among diverse sets of expert advisers can both improve the quality of expert advice and make it harder for political leaders to blur the lines between expert advice and political judgments. We highlight the importance of institutional design in managing the politics of expert advice

Post-Truth Politics and the Competition of Ideas

“Post-truth” politics is often framed as a failure of the competition of idea­s. Yet there are different ways of thinking about the competition of ideas, with different implications for the way we understand its benefits and risks. The dominant way of framing the competition of ideas is in terms of a marketplace, which, however, obscures the different ways ideas can compete. Several theorists can help us think through the competition of ideas. J. S. Mill, for example, avoided the metaphor of the market by focusing, instead, on competition as the testing of arguments in adversarial encounters before a critical audience. Georg Simmel, alternatively, conceived of competition as a form of indirect conflict, where two individuals strive in parallel to gain audience approval. This view emphasizes innovation and creativity in the competition of “all for all.” More recently, theorists have developed the market logic of competition by thinking of a marketplace not for ideas but for rationalizations. This articulates some of the features of Simmel’s view of competition, but underestimates the degrees of constraint required to secure the goods of competition. Ultimately, recognizing these different modes of competition in the public sphere can enrich our theories of deliberative democracy and sharpen our view of the problem of “post-truth” politics

Democratic Non-Participation

The idea that there might be democratic forms of non-participation has been largely overlooked in the theoretical and empirical literature on democracy. Non-participation has variously been seen as a threat to the proper functioning of democracy, a rational choice, or (more rarely) as potentially beneficial at the systems level. We argue that there are forms of non-participation that may be justified on democratic grounds. Our main theoretical move is to distinguish between reflectivity (or thoughtfulness) and participation. We argue that the normative value of both participation and non-participation is conditioned by reflectivity, such that there may be democratically desirable forms of reflective non-participation. To support our claims, we provide examples of how non-participation can help support democratic goods — such as inclusion, influence, and legitimacy — that are normally associated only with democratic participation

Deliberation and Identity Rules : The Effect of Anonymity, Pseudonyms and Real-Name Requirements on the Cognitive Complexity of Online News Comments

How do identity rules influence online deliberation? We address this question by drawing on a data set of 45 million comments on news articles on the Huffington Post from January 2013 to May 2015. At the beginning of this period, the site allowed commenting under what we call non-durable pseudonyms. In December 2013, Huffington Post moved to regulate its forum by requiring users to authenticate their accounts. And in June 2014, Huffington Post outsourced commenting to Facebook altogether, approximating a ‘real-name’ environment. We find a significant increase in the cognitive complexity of comments (a proxy for one aspect of deliberative quality) during the middle phase, followed by a decrease following the shift to real-name commenting through Facebook. Our findings challenge the terms of the apparently simple trade-off between the goods and bads of anonymous and real-name environments and point to the potential value of durable pseudonymity in the context of online discussion

Efficiency and safety of varying the frequency of whole blood donation (INTERVAL): a randomised trial of 45 000 donors

Background: Limits on the frequency of whole blood donation exist primarily to safeguard donor health. However, there is substantial variation across blood services in the maximum frequency of donations allowed. We compared standard practice in the UK with shorter inter-donation intervals used in other countries. Methods: In this parallel group, pragmatic, randomised trial, we recruited whole blood donors aged 18 years or older from 25 centres across England, UK. By use of a computer-based algorithm, men were randomly assigned (1:1:1) to 12-week (standard) versus 10-week versus 8-week inter-donation intervals, and women were randomly assigned (1:1:1) to 16-week (standard) versus 14-week versus 12-week intervals. Participants were not masked to their allocated intervention group. The primary outcome was the number of donations over 2 years. Secondary outcomes related to safety were quality of life, symptoms potentially related to donation, physical activity, cognitive function, haemoglobin and ferritin concentrations, and deferrals because of low haemoglobin. This trial is registered with ISRCTN, number ISRCTN24760606, and is ongoing but no longer recruiting participants. Findings: 45 263 whole blood donors (22 466 men, 22 797 women) were recruited between June 11, 2012, and June 15, 2014. Data were analysed for 45 042 (99·5%) participants. Men were randomly assigned to the 12-week (n=7452) versus 10-week (n=7449) versus 8-week (n=7456) groups; and women to the 16-week (n=7550) versus 14-week (n=7567) versus 12-week (n=7568) groups. In men, compared with the 12-week group, the mean amount of blood collected per donor over 2 years increased by 1·69 units (95% CI 1·59–1·80; approximately 795 mL) in the 8-week group and by 0·79 units (0·69–0·88; approximately 370 mL) in the 10-week group (p<0·0001 for both). In women, compared with the 16-week group, it increased by 0·84 units (95% CI 0·76–0·91; approximately 395 mL) in the 12-week group and by 0·46 units (0·39–0·53; approximately 215 mL) in the 14-week group (p<0·0001 for both). No significant differences were observed in quality of life, physical activity, or cognitive function across randomised groups. However, more frequent donation resulted in more donation-related symptoms (eg, tiredness, breathlessness, feeling faint, dizziness, and restless legs, especially among men [for all listed symptoms]), lower mean haemoglobin and ferritin concentrations, and more deferrals for low haemoglobin (p<0·0001 for each) than those observed in the standard frequency groups. Interpretation: Over 2 years, more frequent donation than is standard practice in the UK collected substantially more blood without having a major effect on donors' quality of life, physical activity, or cognitive function, but resulted in more donation-related symptoms, deferrals, and iron deficiency.

A mechanoelectrical mechanism for detection of sound envelopes in the hearing organ

To understand speech, the slowly varying outline, or envelope, of the acoustic stimulus is used to distinguish words. A small amount of information about the envelope is sufficient for speech recognition, but the mechanism used by the auditory system to extract the envelope is not known. Several different theories have been proposed, including envelope detection by auditory nerve dendrites as well as various mechanisms involving the sensory hair cells. We used recordings from human and animal inner ears to show that the dominant mechanism for envelope detection is distortion introduced by mechanoelectrical transduction channels. This electrical distortion, which is not apparent in the sound-evoked vibrations of the basilar membrane, tracks the envelope, excites the auditory nerve, and transmits information about the shape of the envelope to the brain.Funding Agencies|Swedish Research Council [K2014-63X-14061-14-5, 2017-06092]; Torsten Soderberg foundation; Strategic research area for systems neurobiology (Region Ostergotland); Linkoping University; NIH-NIDCD [R01 DC-004554, R01 DC 000141]</p

Small Platforms, High Return: The Need to Enhance Investment in Small Satellites for Focused Science, Career Development, and Improved Equity

In the next decade, there is an opportunity for very high return on investment of relatively small budgets by elevating the priority of smallsat funding in heliophysics. We've learned in the past decade that these missions perform exceptionally well by traditional metrics, e.g., papers/year/\$M (Spence et al. 2022 -- arXiv:2206.02968). It is also well established that there is a "leaky pipeline" resulting in too little diversity in leadership positions (see the National Academies Report at https://www.nationalacademies.org/our-work/increasing-diversity-in-the-leadership-of-competed-space-missions). Prioritizing smallsat funding would significantly increase the number of opportunities for new leaders to learn -- a crucial patch for the pipeline and an essential phase of career development. At present, however, there are far more proposers than the available funding can support, leading to selection ratios that can be as low as 6% -- in the bottom 0.5th percentile of selection ratios across the history of ROSES. Prioritizing SmallSat funding and substantially increasing that selection ratio are the fundamental recommendations being made by this white paper.Comment: White paper submitted to the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033; 6 pages, 1 figur
