The data quality on Amazon Mechanical Turk (mTurk) has suffered for years now (Chandler & Paolacci, 2017; Moss & Litman, 2018; Chmielewski & Kucker, 2019; Ahler et al., 2020; Kennedy et al., 2020; MacInnis et al., 2020). There are a few ways to protect online survey data quality. In this post, I will briefly cover five strategies for weeding out junk data in online research (not just via mTurk), from easiest to hardest.Continue reading 5 Ways To Overcome Junk Data From mTurk (and online surveys more generally)
Why did otherwise life affirming people flout public health recommendations during the COVID-19 pandemic?
- Was it leaders’ messaging? For example, are “flatten the curve” graphs about statistical victims less effective than information about identifiable victims?
- Was it people’s reasoning? Do some people not think carefully enough about public health? Might people who better at math better understand public health information involving concepts like exponential growth and probability?
- Was it people’s philosophical preferences? Do some people just care more about preventing harm? Do others prioritize personal liberty over pubic health? Do people’s beliefs about science matter? Religion?
Michał Białek and I investigated. In short, we found that flouting public health recommendations was less about messaging or reasoning than philosophical beliefs, especially beliefs about our duties to others, liberty, and science. The paper is
under review now published in Cognition. As always, you can find a free copy of the paper on my CV at byrdnick.com/cv. More details below.
My colleagues and I are deeply saddened about the unexpected passing of Anders Ericsson on June 17. Dr. Ericsson was not only a massive figure in psychology, philosophy, performance, and beyond but—in my experience—an outstanding person.
There is much to say about Anders. I can speak only to the past few years—and only a slice of it. Nonetheless, that slice of Anders is rich. Indulge me just three stories.Continue reading Anders Ericsson (1947-2020)
I’ll be presenting new data from a pre-registered replication at some conferences in the next few months. The study replicated findings that those with a Ph.D. in philosophy are more reflective, that less reflective philosophers tended towards certain philosophical views, and that some of these reflection-philosophy correlations are partly explained or mediated by culture, education, gender, and personality. Here’s a handout from some presentations that I’ll be giving in 2020.
A 2019 paper in the Advances in Methods and Practices in Psychological Science found that most psychology textbooks, instructors, and students misinterpret ‘statistical significance’ and p values. Talk about a headline! More important than the headline, however, are the right interpretations and what we can do to correct widespread misinterpretations. In this post, I explain the authors’ findings and the three solutions they propose.Continue reading The meaning of ‘statistical significance’ and of p-values
One of the things that I worked on in 2018 was a dissertation about the roles of reflective reasoning in philosophy, morality, and bias. Pending a follow-up study for one chapter, every chapter is written and has enjoyed at least one round of comments—and some of the chapters are under review. As the chapters find homes in journals, I will be sure to post preprints and links to the online publication on my blog and in my social media feeds. So, ya know, follow those if you want more updates. In this post, I’ll give you drafts of the abstracts for each chapter, so that you can get a birds-eye view of the dissertation project.†
