In preparation for the next episode, in which we discuss this paper, here is a reading of:
Skinner, B. F. (1956). A case history in scientific method. American Psychologist, 11(5), 221-233.In today’s episode, we discuss critically reading and appraising scientific articles. How do we select which articles to read carefully? Which heuristics are useful for assessing paper quality? And do open science practices actually lead to better quality papers? Enjoy.
Shownotes
In this episode, we talk about academic societies, professional organizations, and academic advocacy groups, focusing primarily on the discipline of psychology. What are their roles and responsibilities? Is it necessary for researchers to join such organizations? And should we bring back scholarly soirees? Enjoy.
Shownotes
In this episode, we discuss review boards for research with human subjects. Are they necessary? Are they efficient? Are scientists well equipped to make judgements about ethics? And are economists more ethical than psychologists?
Shownotes
In this episode, we discuss activism in science. How do political and personal values affect science? When is activism just part of the job? And should one be careful about activism in the classroom? Enjoy.
Shownotes:
In this episode, we continue our discussion of replications. We talk about how to analyze replication studies, which studies are worth replicating, and what is the status of replications in other scientific disciplines.
Shownotes
In the next two episodes, we will discuss replication studies, which are essential to building reliable scientific knowledge.
Shownotes
In this episode, we discuss a fun mix of eponymous laws, which are laws named after individuals who postulate them.
Shownotes
In this final episode of the three-part series on the Philosophical Psychology lectures by Paul Meehl, we discuss lectures 6-8, which cover the ten obfuscating factors in "soft areas" of psychology and a host of advice Meehl provides for researchers, reviewers, editors, and educators on how to improve practice.
Shownotes
In this episode, we continue the discussion of Meehl's Philosophy of Psychology course, focusing on lectures 3, 4, and 5.

In advance of the next three episodes discussing the Philosophical Psychology lectures by Paul E. Meehl, we present a brief reading from his autobiography in A history of psychology in autobiography.
In this episode, we discuss objectivity and disinterestedness in science. We talk about norms, values, interests, and objectivity in research practice, peer review, and hiring decisions. Is it possible to be completely objective? Is objectivity a feature of epistemic products or epistemic processes? And most importantly, how would you objectively rate this podcast?
Shownotes
In this episode, we discuss the role of criticism in science. When is criticism constructive as opposed to obsessive? What are the features of fair and useful scientific criticism? And should we explicitly teach junior researchers to both give and accept criticism?
Shownotes:
In this episode, we continue discussing Dubin’s 8-step method for theory building. We discuss the measurement of theoretical constructs, using logical propositions to make falsifiable predictions from theories, and the importance of specifying boundary conditions.
Shownotes
In this episode we discussed the 8-step method of theory building proposed by Robin Dubin in his classic 1969 book Theory Building.
Shownotes
In this episode, we discuss the barriers to cumulative science, including inconsistent measurement tools, overreliance on single studies, and the large volume of research publications. Can replications, interdisciplinary collaborations, and prospective meta-analyses help us solve this issue? Can AI solve all our problems? And do most scientists treat their theories like toothbrushes?
Shownotes
In today’s episode, we continue our conversation about preregistration. How flexible can we be when we preregister, without increasing flexibility in our analysis? How well do people preregister, and what does a good preregistration look like? And how do we deal with deviations from preregistrations?
Shownotes
In this two part episode we discuss the fine art of preregistration. We go back into the history of preregistration, its evolution, and current use. Do we preregister to control the Type 1 error rate, or to show that we derived our prediction from theory a priori? Can and should we preregister exploratory or secondary data analysis? And how severe is the issue of severe testing?
Shownotes
In the first episode of 2024, we discuss the double-edged sword: reverence to authority. Should scientists respect others on whose shoulders they stand? Or should they be wary of appeal to authority? How should scientists deal with other sources of authority in science, like for example, the government or academic societies? And how can we differentiate true expertise from mere authority? Enjoy.

In today’s episode, we discuss the role of mentorship in academia. What are the characteristics of a good mentor-mentee relationship? What are the qualities of good mentors and good mentees? Does mentorship play a role in the development of scientific knowledge? And could mentors and mentees benefit from couples therapy?
Note: D.I.H.C is pronounced 'dick' but this is meant to be a family-friendly podcast :)
Shownotes
In this episode, we discuss the role of trust in science. Why should we verify but trust other scientists? What are the prerequisites for building trust within the scientific community? Who is ultimately responsible for verifying our claims and practices that bolster those claims? And should we give personality tests to everyone who enters academia?
Shownotes
In advance of our episode Verify but Trust, a reading of John Hardwig's paper The Role of Trust in Science.
In today’s episode, we discuss the peer review process---its history, its present, and its future. How does peer review work? How long has it existed in its current form? Should reviews be open and signed? Should reviewers be paid for their hard labor? Should we just abandon the peer review process, or does it have a positive role to play?
Shownotes
In this episode, we discuss Quantifauxcation, described by statistician Philip Stark as “situations in which a number is, in effect, made up, and then is given credence merely because it is quantitative.” We give examples of quantifauxcation in psychology, including errors of the third kind. We spend the second half of the podcast discussing how to develop quantitative measures that are meaningful and bridge the divide between qualitative and quantitative observations.
Shownotes
In preparation for a discussion on Quantifauxcation, a reading of 'Problem-Centering vs. Means-Centering in Science' by Abraham H. Maslow (1946).
In today’s episode, we discuss intellectual vices. How can we tell the difference between justified confidence and unjustified arrogance? How do we deal with feelings of envy or negative comparison with other scientists? What is the difference between building one’s career and careerism? And what do we do about scientists who do not care about the truth?
Shownotes
In this episode, we discuss scientific snobbery and the ways in which it affects our interactions with and perceptions of other scientists. What are the reasons for hierarchies among different disciplines, institutions, and approaches to science? What are some ways in which snobbery manifests in science? And is it snobby to not want to present scientific posters? Enjoy.
Shownotes:
In this episode, we continue our conversation on the replication crisis⏤Which methodological, theoretical, and practical concerns did psychologists raise half a century ago? What has changed, and what remains the same, during the current crisis?
Shownotes
Reading of the chapter "Investigator Data Analysis Effect" from the book:
Barber, T. X. (1976). Pitfalls in Human Research: Ten Pivotal Points. Pergamon Press.In this episode, we discuss the replication crisis in psychology which has been an important topic of discussion for the last decade. We revisit some key events from the start of the replication crisis, such as the publication of Daryl Bem's studies on precognition, the paper False Positive Psychology, and the Reproducibility Project and share personal anecdotes about how it was to live through the replication crisis.
Shownotes:
In this episode we reflect on the role of intelligence in scientist. How much does intelligence matter in science, and which other characteristics might play a role in doing good science? Do scientist need to be extremely intelligent or can anyone do science? And what is the role of stupidity in science?
Capax Mentis roughly translates to "capacity of mind."
Smriti stupidly messed up her audio so the quality isn't great. Apologies!
Shownotes
As prologue to the next episode on how smart one needs to be to be a scientist, we present a reading of chapter 2 "How can I tell if I am cut out to be a scientific research worker?" by Peter B. Medawar from his 1979 book 'Advice to a young scientist'. Our next episode was inspired by the section "Am I brainy enough to be a scientist?"
https://www.google.nl/books/edition/Advice_To_A_Young_Scientist/3fg3DgAAQBAJ
In this episode we discuss Daniel Dennett's distinction between chess, or research worth doing, and 'chmess,' research not worth doing. We discuss ways to determine whether our research is chess or chmess, and how to avoid being sucked into lines of research we don't particularly care about.
Shownotes
As prologue to the next episode on Chmess, we present a reading of a paper by Daniel C. Dennett:
In today's episode, we discuss vocational virtues⸺scientific principles that should guide the behavior of scientists. We discuss whether we agree with values put forth by numerous scientists, including Ivan Pavlov, Peter Medawar, Santiago Ramón y Cajal, Barry Schwartz, among others, and share our own.
Correction: At 56:24, Smriti mentions the book This is Biology, which is written by Ernst Mayr, not E.O. Wilson.
Shownotes
As prologue to the next episode on vocational virtues, we present a reading of a paper by Barry Schwartz:
Schwartz, B. (2022). Science, scholarship, and intellectual virtues: A guide to what higher education should be like. Journal of Moral Education, 51(1), 61-72. https://doi.org/10.1080/03057240.2020.1772211 (Published online: 19 Jun 2020)

An episode from Smriti's previous podcast with Paul Connor where they discussed the paper with Barry can be found here.
In this episode, we discuss the topic of research waste. We discuss what it is it that is being wasted and whether we waste fewer scientific resources and talent through coordination, team science, and better planning.
Shownotes
In this bonus episode, Daniël reads Chapter 5 of John Desmond Bernal’s book The Social Function of Science, entitled The Efficiency of Scientific Research in preparation of our upcoming podcast episode on research waste.
Shownotes
In this episode, we discuss the issue of publication bias. We discuss issues like: Do we learn anything from null results, given the current state of research practices? Is poorly done research still worth sharing with the scientific community? And how can we move toward a system where null results are informative and worth publishing?
Shownotes
In this episode, we discuss physicist Richard Feynman’s famous speech ‘Cargo Cult Science,’ which refers to work that has all the affectations of science without the actual application of the scientific method. We also discuss topics like: What is pathological science? How might cargo cult science and pathological be different from pseudo-science? How do we know whether or not we’re in a cargo cult, and what can we do to make sure we're not fooling ourselves?
Shownotes
In this bonus episode, we present a reading of the famous speech by physicist Richard Feynman on "science that isn't science," Cargo Cult Science, which will be the topic of the next episode. Enjoy.
In this episode we discuss regulatory bodies their influence on the generation and dissemination of knowledge. Should regulatory bodies have the authority to affect the topics and methods of science? Is more highly regulated research actually better? And should we just give up on our own lines of research and become potato researchers?
Shownotes
In this episode, we discuss the importance of consensus in science, both as means of establishing true knowledge and for determining which research questions might be worth pursuing. We also discuss barriers to reaching consensus and the different frameworks that are currently employed for trying to reach consensus among important stakeholders.
Shownotes
In this episode, we discuss the insatiable itch to publish, starting with a quote from 1927 by sociologist Clarence Case on the dictum “Publish or perish.” We discuss ways in which individual goals to publish conflict with the broader scientific goal of producing useful knowledge. We also question the assumptions behind the notion that publishing less would be beneficial for science.
Shownotes
In this episode, we discuss the role of eminence in science. What ask questions like: What makes scientists eminent? What role does eminence play in science? Can eminence be spread across scientific teams instead of individuals? And how can we recognize and applaud scientists for their contributions, while avoiding conferring too many benefits on scientists who do become eminent?
Shownotes
In our third episode, we discuss confirmation bias, which affects not only how scientists generate and test their own hypotheses, but also how they evaluate the scientific evidence presented by others. We discuss guardrails against confirmation bias that are already in place, and others that could potentially improve scientific practice if adopted.
Shownotes
In our second episode, we discuss the role of skepticism in science, a topic that relates closely to the title of our podcast. Given that the scientific enterprise is essentially an exercise in organized skepticism, how can we maintain a healthy amount of skepticism while also ensuring that scientists don't slip into cynicism or nihilism?
Shownotes
In our first episode, we discuss a quote from the preface to The Instauratio Magna (of which Novum Organum is a part), in which Bacon claims that scientists should be motivated to do science for the betterment of mankind, and not for personal motives like fame, fortune, or even fun.
Here is the tweet (by Heidi Seibold) on academia not being aligned with good scientific practices.
An unedited transcript of the episode can be found here.
In this introductory episode, Daniël and Smriti share which podcasts they like, why they are starting their own, and how their connection to each other is also tied to podcasting. They also talk about the theme of the podcast, which is inspired by Francis Bacon’s delineation of the scientific method 400 years ago.
