Concerns about ubiquitous recording are not new. Decades before “smart” devices or traffic cameras were ambiently recording us, we let other digital systems have our sensitive information. We recall 3 not-yet-surmounted issues with deploying this #tech: doi.org/10.1080/1526...
Katherine Saylor and Nick Byrd raise three long-standing issues related to the deployment of ambient recording or ambient intelligence technology:

(1) institutions tend to be averse to rigorous testing and evaluation, settling for mere pre-post or other research designs that can't assess cause-and-effect;

(2) even when proper pre-deployment experiments happen, it may be impossible to operationalize ethical outcomes that do not favor some vulnerable groups over others; 

and (3) standard ethical frameworks assume just two parties (scientist-participant, doctor-patient, company-user, gov-citizen) and thus fail to account for the multiplicity of (often not-yet-consenting) parties that have interests in the sensitive digital records we create and store.

Are conspiracy theorists distinguished more by ideology or something else? Stanovich & Toplak found belief in secret causes, #religion, and the paranormal predicted discernment between true and false #conspiracyTheories almost as well as #ideology. 🔒 doi.org/10.1002/acp....
"the paranormal beliefs measure and the religiosity measure tended to steal variance from each other in various regression and path models. We thus developed separate models involving each (the model involving paranormal beliefs is presented in Figure 3, and that involving religiosity is presented in Figure 4)."

In Figure 3, "The ability to discriminate true from false conspiracies has a positive independent relationship with AOT, and negative independent relationships with [belief in hidden causal forces or] HCFS, Paranormal Beliefs, and the Government Credulity scale."

In Figure 4, "The ability to discriminate true from false conspiracies has a positive independent relationship with AOT, and negative independent relationships with HCFS, Religiosity, and the Government Credulity scale that were all very similar to the coefficients observed in Figure 3.""Table 2 presents the correlations of the predictor variables with the six variables measuring partisan/ideological conspiracy belief. As is apparent, the ideology variable has substantial correlations (although in different directions) with all six of the partisan/ideological conspiracy variables. Some variables, such as the Paranormal Belief [and Religiosity] scale[s], had fairly uniform positive relationships with conspiracy beliefs across the ideological spectrum."

Some cognitive tests try to determine if people considered the prevalence of something (e.g., a disease). Are these good tests of "reflective" reasoning? Perhaps! People who neglected such relevant evidence also performed worse on other reflection tests.

Patterns between evidence seeking behaviors, reasoning, and cognitive reflection: A supervised clustering approach
In the face of risk, decision-making can be driven by styles of evidence gathering and information processing. When studying how people navigate the complex landscapes of evidence, researchers face the analytical problem of an exponentially growing number of distinct evidence gathering styles, as the number of pieces of information increases. The existing solution is to chunk information into a manageable number of pre-defined categories. In this work, we propose to meet this analytical challenge with a two-pronged strategy. First, our observational setting offers more fine-grained pieces of evidence but masks the content of evidence behind a query (e.g., ’what does so-and-so say?’) to ensure that people only access what they deem as potentially relevant. Second, applying supervised clustering based on the SHapley Additive exPlanation (SHAP) methodology allows us to relate evidence from gathered patterns to final decision while significantly relaxing theoretical delineations of evidence types that would otherwise make analysis intractable. We argue that this two-pronged strategy approximately integrates the pathway from evidence seeking to information processing and decision-making. We applied this strategy to demonstrate the fruitfulness of bridging work on evidence gathering and information processing. For example, one mental shortcut (heuristic) to arrive at decisions when assessing a causal claim using a 2×2 contingency table is the ‘base rate neglect heuristic’ (considering only the treatment group, comparing the number of positive outcomes to the number of negative outcomes). While base rate neglect is a well-established heuristic in information processing research, there is not yet a clear equivalent picture regarding evidence gathering. We develop this picture by considering the assessment of the effectiveness of a hypothetical nasal spray based on queries that span gathering/processing evidence categories. Using a demographically diverse online sample collected during August 2024 in the United States, we establish that the base rate neglect heuristic from information processing research is also a heuristic when it comes to gathering first-order data. For example, we find that higher performance on the cognitive reflection test predicts selection of the full data of a 2×2 contingency table. But, the latter group is nevertheless similar to base rate neglecters in who they consider to be relevant outside sources (i.e., they have roughly the same “deference” behavior). So while evidential categories in information seeking research are well suited to track differences in deference behaviors, they are blind to the difference between these two groups. These findings are additionally important for designing tailored health communication so as to avoid fallacious inferences.

Do we use #AI because it’s trustworthy? A dissertation's first experiment did not find that the reliability of a #chatbot or people's self-reported trust in it predicted re-using it. Not just an attitude-behavior gap, but a reliability-reliance gap? 🔓doi.org/10.18419/opu...

Why might some workers perform better? A thesis found reflective thinking predicted #job performance above and beyond #intelligence and conscientiousness: ir.library.illinoiss... Reflection even moderated the relationship between #IQ and performance! #IOPsych #Hiring #Work #AI
"...the predictive power of [general cognitive ability or GCA] is significantly attenuated as [cognitive reflection or CR] increases. As shown in Figure 1, the relationship between GCA and job performance [or JP] was positive and statistically significant across both tested levels, but the magnitude of the effect differed substantially. For individuals with lower CR scores (-1 SD), GCA was a very strong and significant predictor of JP (B = 0.16, SE = 0.03, t = 5.77, p < .001). This confirms that for individuals with lower CR raw GCA is a critical driver of JP. Conversely, for individuals high in CR (SD +1), the relationship was notably attenuated, with the slope coefficient reduced by nearly half (B = 0.08, SE = 0.03, t = 3.12, p = .002). While still significant, GCA becomes a much less critical predictor of JP when high levels of CR are present."

Pragmatism, Dual-Process Theory, and the Study of Reflective Cognition

Gordon Brett

This article advances dual-process theory (DPT) by developing a pragmatist framework for the study of reflective cognition. Although dual-process models were introduced to sociology via Bourdieusian practice theory, Bourdieusian DPT has proven inadequate for theorising reflective cognition and action, with sociologists looking to pragmatism as an alternative. To support these efforts, I provide a synthetic, elemental account of the pragmatist theory of reflection, delineating reflective cognition's defining characteristics, core components, its relationship with non-reflective cognition, and its interindividual variation. I then outline the merits of the pragmatist theory of reflection for dual-process research, arguing that it not only addresses the major limitations of Bourdieusian DPT but that it has broad interdisciplinary support [and] provides advantages [to both science and scholarship].

"some words of caution are in order. First, some of reflection’s cognates (e.g., “critical thinking”) will not map so neatly onto talk about System or Type 2 reasoning (Bonnefon 2018). Importantly, reflection is a more general category than critical thinking: reflection can be used for non-critical ends." –Byrd 2025 (Res Philosophica)"Although critical thinking typically involves Type 2 processing, the latter is not a necessary condition for it. Critical thinking can also occur automatically—that is, as a form of Type 1 thinking. One reason this is possible is that at least some standards of rationality can be internalized to the point of automaticity. As a result, alongside an incorrect intuitive response, System 1 may also generate a correct one...."

Do people process #ChatGPT recommendations lazily or reflectively? Three randomized experiments manipulated #AI output order, errors, and alleged reliability. Users showed a “first‑is‑best” #bias — less so when warned about the unreliability of #LLMs. doi.org/10.1016/j.el...
First-is-best heuristic resultThe two "regulatory focus" conditions (about the alleged reliability of the AI models).The first-is-best heuristic was less pronounced in the condition that warned people about the unreliability of LLMs.The unreliability warning's effect on first-is-best heuristic was somewhat mediated by decision time.

I'm at #Harvard for #BSPA2026 sharing new #bioethics results about identity, #law, and #medicine. I'll post more from BSPA on Bluesky. Our poster: Intuitions about a real #neurology case implied #PhineasGage effects may be more about point-of-view and physicality than morality.

If someone changes morally, are they the ‘same’ person? It depends!

Case: “[you/Alex] are extremely [kind/cruel]; [you/Alex] really enjoy[s] [helping/harming] people. [you/Alex have/has] had steady jobs and stable relationships. However, later in the year something changed. In some ways [you/Alex] after the change [are/is] remarkably different from [you/Alex] before the change. [You/Alex] before the change [were/was] extremely [kind/cruel] and enjoyed [helping/harming] people, but [you/Alex] after the change [are/is] now extremely [cruel/kind]; [you/Alex] even enjoy[s] [harming/helping] people.

...[you/Alex] received a full neurological examination, revealing a large egg-sized tumor in [you/Alex’s] brain. The doctors removed the brain tumor and [you/Alex] promptly recovered from surgery. However, after the surgery, something changed. In some ways [you/Alex] after the surgery [are/is] remarkably..."We ran an experiment comparing 2 morality conditions (deterioration vs. improvement) and 2 point-of-view conditions (1st- vs. 3rd-person) across two repeated decisions about a more-or-less unexplained moral change and then — after doctors identified and removed a brain tumor — another moral change back to baseline. Over 200 people assessed a vignette adapted from a real neurology case report of someone who experienced two sequential moral changes (Burns & Swerdlow 2003). 

The plot shows point-of-view effects at both decision points, but no Phineas Gage effect (or moral change effect). The plot also shows that no other controlled variable reliably predicted variance in the decisions about identity.ABSTRACT
Pixar’s Inside Out depicts the self as fragmented, with interacting and sometimes competing agents. Putting aside the film’s unscientific embellishments, cognitive science does find people seeing other people as more fragmented over time if those people change for the worse (morally) than if change for the better — also known as the so-called Phineas Gage or Moral Direction effect (Strohminger & Nichols PMID: 24503450; Tobia 2015 DOI: 10.1093/analys/anv041).

Our results raise various questions:
- Are intuitions about personal identity more about POV or physicality than ethics?
- Should ethical, legal, or medical norms or decisions involving identity be framed first-personally or third-personally? Both?
- Should the physicality of moral change be relevant, ethically? Legally? Medically?
