Ask yourself these true or false questions: Generalizability and transportability and external validity are all the same thing Generalizability is a secondary concern to internal validity We spend too much time in epi training programs teaching internal validity and not enough teaching external validity Worrying about external validity is largely and academic exercise that doesn’t really have much in the way of real-world impact. In this episode of SERious Epi we discuss these questions and more with Dr. Megha Mehrotra. While internal and external validity are familiar to nearly all epidemiologists, the concept of transportability is less familiar. Listen in to this episode for a clear description of how concepts related to validity, generalizability, and transportability are similar, and different, from each other.  

Thought experiments have played a crucial role in the development of mathematics, philosophy, and science. As implausible as it may seem, reasoning a priori, comfortably from our armchairs, can actually teach us about the real world and drive progress in our understanding. Even ethical thought experiments have changed the minds and influenced the behavior of those who have been presented with them. Though this is a rare occurrence, it has been known to happen.

I’m suspicious of ethical thought experiments. These short hypothetical scenarios are often presented context-free, eliminating morally relevant detail. And in the course of probing our intuitions, they often include detail that we wouldn’t have in the real world. In effect, we end up discussing a world vastly different from our own. The elimination of information that we usually possess and inclusion of information that we don’t ordinarily possess renders many ethical thought experiments worse than useless. They can confuse more than they clarify, derail ethical discussions, and often don’t translate to our lives at all.

In today’s episode, Greg and Patrick start a conversation about how COVID-19 has had an instantaneous and lasting impact on research, what we can do about it right now, and what we can be thinking about for the future as we move forward, together. Along the way they also manage to mention... elevators of blood, Joe Exotic, wisdom of crowds, a fatted ox, skinned knees, intellectual judo, I meant to do that, truck drivin’ subtlety, Apollo 13, hitting a change-up, naive optimism, Thomas Kuhn, and losing your balance.

Ellie Murray and Lucy D'Agostino McGowan chat with Elizabeth Stuart from the Departments of Mental Health, Biostatistics, and Health Policy and Management at the Johns Hopkins Bloomberg School of Public Health.  Here are some links to the content we talk about in this episode:

James Wilson integrates philosophy with other relevant disciplines, such as epidemiology, economics and political theory to explore conceptual and practical challenges in the sustainable and equitable improvement of human wellbeing. He focuses particularly on public health ethics, and the ownership and governance of ideas and information. He received his PhD from UCL in 2002, then held temporary lectureships in Philosophy at University of Roehampton (2002-3) and Birkbeck (2003-4), before becoming Lecturer in Ethics at the Keele University (2004-8). He has been at UCL since 2008, rst as Lecturer in Philosophy and Health, and then as Senior Lecturer in Philosophy. This podcast is an audio recording of Dr. Wilson's talk - 'Internal and External Validity in Thought Experiments' - at the Aristotelian Society on 25 January 2016. The recording was produced by Backdoor Broadcasting Company.

Background: Randomized, double-blind, placebo-controlled trials constitute the gold standard in clinical research when testing the efficacy of new psychopharmacological interventions in the treatment of major depression. However, the blinded use of placebo has been found to influence clinical trial outcomes and may bias patient selection. Discussion: To improve clinical trial design in major depression so as to reflect clinical practice more closely we propose to present patients with a balanced view of the benefits of study participation irrespective of their assignment to placebo or active treatment. In addition every participant should be given the option to finally receive the active medication. A research agenda is outlined to evaluate the impact of the proposed changes on the efficacy of the drug to be evaluated and on the demographic and clinical characteristics of the enrollment fraction with regard to its representativeness of the eligible population. Summary: We propose a list of measures to be taken to improve the external validity of double-blind, placebocontrolled trials in major depression. The recommended changes to clinical trial design may also be relevant for other psychiatric as well as medical disorders in which expectations regarding treatment outcome may affect the outcome itself.

Modern Experimental Method: What is correlation and what does it tell us? Correlation: a statistical technique for describing the extent and direction of the relationship between pairs of scores on some measure. , does not indiact what causes what What can psychological experiments tell us? Experiments, which is psychology’s most powerful tool, assesses cause and effect through strictly controlled procedures and manipulations. Experiment: a careful and controlled study of cause and effect through manipulation of the conditions participants are exposed to. Internal Validity: the extent to which an experiment permits statements about cause and effect. External Validity: the extent to which an experiment applies to real-life behavior. STUDY CHART Methods Used in Psychological Research Observation: a research method in which events are observed and recorded as they occur; with out intervention. Naturalistic Observation: Observing behavior in everyday settings or in a laboratory; the observer attempts to be as inconspicuous as possible. Participant observation: Taking an active part in a social situation and observing the behavior of others in that situation. Interview: a research method in which clients or research participants are questioned about their life experiences and their ideas and feelings about them. Case history: a compilation of significant experiences in a person’s life. Questionnaire: a set of written questions that each participant answers in the same order. Survey: a research method in which a questionnaire is administered to a large number of people in a short period of time. Standardized test: a test that has been developed to assess human abilities, achievements, and traits. (such as personality characteristics) Physiological measures: methods for measuring any form of physiological functioning that is related to behavior. Correlation: a mathematical way of determining the relationship between two pairs of scores. Experiment: a careful and controlled study of cause and effect in which participants or subjects are exposed to differing conditions (independent variable) and any corresponding differences in behavior (dependent variable) are assessed; experiments may be conducted in a laboratory (controlled observation) or naturalistic settings.
