Before psychology, and still concurrent with it, the need to help people with their behavior-change endeavors, mental health concerns, and other problems in living was met by the world’s great religions. For many people religions still serve this purpose, often outside the Western scientific view that considers them unfalsifiable and therefore irrelevant. This scientific myopia means that psychology has a limited perspective on behavior-change practices of religious derivation -- since the time of William James's Varieties of Religious Experience , religion hasn't been considered a respectable area of study. (Interestingly, we have better data about non-Western practices like yoga and meditation, which have been studied in ways cut off from their religious origins. It is mainly Christianity that was seen as outside the purview of scientific comment). One traditional practice common to many religions is the pilgrimage , a journey from home to a distant location in order to view...

My most recent blog post suggested that we aren't going to be able to upload human consciousness to the cloud anytime soon, for various reasons that have to do with the technical differences between human and AI information processing, and the physical differences between computers and human brains. So what about a simpler task, reading people's minds? That's another common trope of fantasy and sci-fi literature, and it seems close to recent advances in the mental control of prosthetic devices . The Neuralink company has also reported successes in this area, along with some ability for people with communication impairments to generate words or phrases on a computer. This seems like it is getting close to reading people's thoughts. Let's leave aside the medical challenges of implanting electrodes in the brain, which are considerable: metal needles can damage sensitive brain tissue, so the body treats the electrode as an injury and attempts to build scar tissue aroun...

It’s a popular sci-fi trope : The human consciousness now residing in a computer, trading physical life for machine-based immortality. In The Matrix this works both ways: You can not only upload your consciousness to a vast multiplayer online world, but also instantly download digitized knowledge from the cloud to your brain (“ I know kung fu! ”). A digitized consciousness might have some acknowledged limitations, sure – you don’t eat anymore, and you can’t smell the flowers. Even that seems ridiculous by modern technology standards, though: Couldn’t we design appropriate sensors, or simply simulate those experiences? Indeed, there’s a school of thought that claims we are already living in some type of simulated reality , whether computer-generated or otherwise. Let’s confine ourselves to currently existing digital technologies, and examine the question of whether it really might be possible to upload our consciousness to the cloud. China is investing a lot in brain-computer interf...

In this post, I will take a look at the Behavior Change Wheel (BCW), a newer framework for understanding health behavior. The model has been around for a decade, but it became much better-known after the book Engaged   featured it in 2020. The BCW model is sometimes called by the name of one of its components, like "the COM-B model." Technically COM-B is just part of the full model diagram, shown above (the green inner circle), so I'm going to refer to the full framework as "the BCW" in this post. As you will see, it might be possible to utilize or accept just one of the BCW's components without necessarily buying into the whole thing. I'm also going to call the BCW a "framework" or "model" instead of a theory. That part comes directly from its creators, who describe the BCW as "a synthesis of 19 frameworks of behavior change found in the research literature" ( Mitchie, Atkins, & West , p. 11). The 19 frameworks are als...

  The scientific environment has changed over the past year, with government agencies canceling previously awarded grants (something that would have been unheard-of before 2025) based on whether they addressed topics related to diversity, equity, and inclusion. Leaving aside the buzzwords for a minute, the focus of these projects was on understanding the experiences of people with a wide range of different life experiences, including some who may not have been well-represented in prior studies. Among my colleagues, some of the targeted grants investigated topics like the mental health of transgender adolescents, the acceptance of HIV prevention interventions, the best ways to promote health among Latino/Latina people, and smoking cessation among people from various gender groups. Researchers have been warned to avoid using certain words in their grant proposals going forward. Now, I recognize that there's political viewpoint diversity in society, and that some people just don'...

I have written previously about how the Intuitive Mind affects type 1 diabetes (T1D) self-management, for example based on people's  situational awareness of changes in their own blood sugar as they occur. In one prior study, our team found that Intuitive-level variables such as motivation and social perception (based on a daily survey) were related to successful daily blood sugar control (based on time-in-range [TIR], a commonly used metric from continuous glucose monitoring [CGM]) among adolescents with T1D. I also wrote about my own experience trying a CGM for 2 weeks, which did seem to result in increased situational awareness. In another study, we found that adolescents' proactive  use of a hybrid closed-loop system (pictured above), which incorporates an insulin pump and a dosing algorithm together with a CGM, resulted in better TIR results than when people waited for the technology to tell them what to do. Specifically, adolescents who looked at their CGM readout l...
