ABSTRACT The current Coronavirus Disease 2019 (COVID-19) pandemic has exerted an unprecedented impact across the globe. As a consequence of this overwhelming catastrophe, long-established prevailing medical and scientific paradigms have been disrupted. The response of the scientific community, medical journals, media, and some politicians has been far from ideal. The present manuscript discusses the failure of the scientific enterprise in its initiatives to address the COVID-19 outbreak as a consequence of the disarray attributable to haste and urgency. To enhance conveying our message, this manuscript is organized into 3 interrelated sections: 1) the accelerated pace of publications coupled with a dysfunctional review pro- cess; 2) failure of the clinical trial enterprise; 3) propagation of misleading information by the media. In response we propose a template comprising a focus on randomized controlled clinical trials, and an insis- tence on responsible journal publication, and enumeration of policies to deal with social media-propagated news. We conclude with a reconsideration of the appropriate role of academic medicine and journals. Ó 2020 Elsevier Inc. All rights reserved.

  • Statistical Inference: Paradigms and Controversies in Historic Perspective
    Jostein Lillestøl, NHH 2014 Statistical inference: Paradigms and controversies in historic perspective 1. Five paradigms We will cover the following five lines of thought: 1. Early Bayesian inference and its revival Inverse probability – Non-informative priors – “Objective” Bayes (1763), Laplace (1774), Jeffreys (1931), Bernardo (1975) 2. Fisherian inference Evidence oriented – Likelihood – Fisher information - Necessity Fisher (1921 and later) 3. Neyman- Pearson inference Action oriented – Frequentist/Sample space – Objective Neyman (1933, 1937), Pearson (1933), Wald (1939), Lehmann (1950 and later) 4. Neo - Bayesian inference Coherent decisions - Subjective/personal De Finetti (1937), Savage (1951), Lindley (1953) 5. Likelihood inference Evidence based – likelihood profiles – likelihood ratios Barnard (1949), Birnbaum (1962), Edwards (1972) Classical inference as it has been practiced since the 1950’s is really none of these in its pure form. It is more like a pragmatic mix of 2 and 3, in particular with respect to testing of significance, pretending to be both action and evidence oriented, which is hard to fulfill in a consistent manner. To keep our minds on track we do not single out this as a separate paradigm, but will discuss this at the end. A main concern through the history of statistical inference has been to establish a sound scientific framework for the analysis of sampled data. Concepts were initially often vague and disputed, but even after their clarification, various schools of thought have at times been in strong opposition to each other. When we try to describe the approaches here, we will use the notions of today. All five paradigms of statistical inference are based on modeling the observed data x given some parameter or “state of the world” , which essentially corresponds to stating the conditional distribution f(x|(or making some assumptions about it).

  • Church Closures, Lancet, Rioters, Planned Parenthood …And Thomas More
    Church Closures, Lancet, Rioters, Planned Parenthood …and Thomas More Click here to watch the video. A couple of weeks ago, I uploaded a video about the coronavirus lockdowns in California, especially with regard to the closure of churches. Since that time, many governors across the nation have issued new rules dictating exactly how many people are allowed to attend church at any given time. In all of California, for example, churches can only open their doors to 25% of their total capacity or 100 people, whichever is less. New Jersey churches can only open to 25 people. Period. In Minnesota, all religious books must be removed from churches, even though the CDC recently came out with new guidance saying the threat of spreading the virus through surface contact is remote. And until a few days ago, religious services in New York were limited to 10 people. A church in Southern California sued the governor in federal court to lift California’s restrictive order. When they lost at the Ninth Circuit Court of Appeals, they petitioned the Supreme Court to review their case. And, thanks to Chief Justice John Roberts, the church lost. It should be noted that the church is located in San Diego county—a county of 3.3 million people that has seen a total of 296 COVID deaths to date. Nevertheless, Justice Roberts gave short shrift to the First Amendment, finding that “Our Constitution entrusts the safety and the health of the people to the politically accountable officials of the States to guard and protect.” In other words, the highly questionable power of governors to lock healthy people in their homes for months on end trumps the express religious rights found in the Constitution.

  • Attenuated Change Blindness for Exogenously Attended Items in a Flicker Paradigm
    VISUAL COGNITION, 2000, 7 (1/2/3), 377–396 Attenuated Change Blindness for Exogenously Attended Items in a Flicker Paradigm Brian J. Scholl Rutgers Center for Cognitive Science, Piscataway, NJ, USA When two scenes are alternately displayed, separated by a mask, even large, repeated changes between the scenes often go unnoticed for surprisingly long durations. Change blindness of this sort is attenuated at “centres of interest” in the scenes, however, supporting a theory of change blindness in which attention is necessary to perceive such changes (Rensink, O’Regan, & Clark, 1997). Prob- lems with this measure of attentional selection—via verbally described “centres of interest”—are discussed, including worries about describability and explana- tory impotence. Other forms of attentional selection, not subject to these prob- lems, are employed in a “flicker” experiment to test the attention-based theory of change detection. Attenuated change blindness is observed at attended items when attentional selection is realized via involuntary exogenous capture of visual attention—to late-onset items and colour singletons—even when these manipulations are uncorrelated with the loci of the changes, and are thus irrele- vant to the change detection task. These demonstrations ground the atten- tion-based theory of change blindness in a type of attentional selection which is understood more rigorously than are “centres of interest”. At the same time, these results have important implications concerning the nature of exogenous attentional capture. It often seems, from the perspective of vision science, that our perceptual sys- tems work too well. They provide us with extremely strong intuitions about how perception works—about how and when we represent visual scenes—which often turn out to be misleading.

  • The Serial Blocking Effect: a Testbed for the Neural Mechanisms of Temporal
    www.nature.com/scientificreports OPEN The serial blocking efect: a testbed for the neural mechanisms of temporal-diference learning Received: 8 January 2019 Ashraf Mahmud1, Petio Petrov1, Guillem R. Esber2 & Mihaela D. Iordanova 1 Accepted: 22 March 2019 Temporal-diference (TD) learning models aford the neuroscientist a theory-driven roadmap in Published: xx xx xxxx the quest for the neural mechanisms of reinforcement learning. The application of these models to understanding the role of phasic midbrain dopaminergic responses in reward prediction learning constitutes one of the greatest success stories in behavioural and cognitive neuroscience. Critically, the classic learning paradigms associated with TD are poorly suited to cast light on its neural implementation, thus hampering progress. Here, we present a serial blocking paradigm in rodents that overcomes these limitations and allows for the simultaneous investigation of two cardinal TD tenets; namely, that learning depends on the computation of a prediction error, and that reinforcing value, whether intrinsic or acquired, propagates back to the onset of the earliest reliable predictor. The implications of this paradigm for the neural exploration of TD mechanisms are highlighted. Error-correcting algorithms as specifed by associative (e.g.)1 and temporal-diference reinforcement learning (TDRL; e.g.)2 models have provided a particularly useful theory-driven approach to examining how learning is implemented in the brain. Indeed, uncovering the neural signature of TDRL has been at the forefront of brain science for decades. However, the extent to which TDRL’s two fundamental assumptions can be dissected at the neural level has been limited by the traditional learning paradigms available.
