Revising deference: Intuitive beliefs about category structure constrain expert deference

Publication date: August 2017 Source:Journal of Memory and Language, Volume 95 Author(s): Alexander Noyes, Frank C. Keil Concepts are grounded in intuitive theories, yet intuitive theories are often sparse and incomplete. Deferring to experts can potentially fill those gaps. Sometimes experts convey new information, such as discovering a new planet (Experiment 1 and 3). Other times they revise past conclusions, such as concluding that Pluto is actually not a planet (Experiment 2 and 3). For non-experts to maintain scientific accuracy, they need to assimilate the expert judgments in either case. However, we find that people are less likely to defer after revision than novel discovery. In each case, their essentialist intuitions explain the pattern of results. The more participants construe categories in essentialist terms, the more they reject category revision; the opposite occurs for novel discoveries. Moreover, people only reject revision when it conflicts with essentialist intuitions (Experiment 4). Thus, the same intuitive theories that encourage deference also constrain it.

ConclusionsA MEL‐A2 with novel composition and surface activities was efficiently produced from a novel MEL producer. This is the first report on production of MEL‐A2 as the major product and from soybean oil. The biosurfactant has potential application as a wetting agent and oil‐in‐water emulsifier. Significance and Impact of the StudyDiscovery of novel structures and novel strains is valuable for further commercial development and application of MELs. Sporisorium sp. aff. sorghi SAM20 can be considered as a potential candidate for commercial production of biosurfactants.This article is protected by copyright. All rights reserved.

This article is protected by copyright. All rights reserved. The phosphodiesterase VieA regulates gene expression by modifying the intracellular cyclic diguanylate pool. This article reveals the differential regulation of VieA in Vibrio cholerae O1 biotypes. Expression of VieA is repressed by the nucleoid‐associated protein H‐NS and the LysR‐type regulator LeuO in classical biotype V. cholerae, and by H‐NS and the quorum sensing regulator HapR in the El Tor biotype.

We describe approaches for back‐calculating model parameter estimates and their standard errors from available summary statistics with various techniques, including approximate Bayesian computation. We propose to use a quadratic approximation to the log‐likelihood for each historical trial based on 2 independent terms for the log mean rate and the log of the dispersion parameter. A Bayesian hierarchical meta‐analysis model then provides the posterior predictive distribution for these parameters. Simulations show this approach with back‐calculated parameter estimates results in very similar inference as using parame...
