How does attention shape addiction?

The new research reflection published in the Journal of Trial and Error suggests it might not be as straightforward as once thought.

In “Attentional bias and to***co smoking frequency: A reflection on Bartlett et al. (2022),” Copeland examines findings from Bartlett and colleagues, who tested whether daily and non-daily smokers differ in the significance of their attention to smoking cues. She argues that the widely used visual probe task has poor reliability and that there is no meaningful difference in attention.

Rather than treating attentional bias as a fixed trait, the paper argues that for to***co smokers, it’s a dynamic, context-dependent process. This process is shaped by moment-to-moment motivation, craving, and environment. The author also commends Bartlett et al. for their open-science approach, including pre-registration, data transparency, and honest reporting of coding errors. These model practices foster trust and increase accuracy in scientific research.

Looking forward, integrating eye-tracking, computational modelling, and real-world data may finally reveal how attention and value interact in addiction.

Is the foundation of scientific research crumbling?

Scientific progress is incremental - it builds on the knowledge base of previous research. This requires the knowledge base to be self-correcting: problematic articles must be flagged and fixed or retracted. But in some fields, the self-correction process seems to be under pressure.

Researchers of the Radboud University studying brain injury after hemorrhage found such a field. Despite many studies being done on this topic, there are still no effective remedies against this complication. However, when they decided to conduct a systematic review of animal studies in the field, they found an unusually high number of articles that claimed successes with many different drugs tested.

After a brief comparison of the articles identified some suspicious image-duplication, they changed their research goal and started looking for problematic images. Using multiple tools and methods, they found that a shocking 40% of papers on this topic had image-related issues. Including, for example, reusing (parts of) the same image for different experimental conditions, suggesting either manipulation or a lack of data oversight.

While genuine mistakes can happen, the high number of problems lead the researchers to conclude that the self-correction of knowledge in this field has stalled. If problematic papers aren’t being flagged, and if flagged papers aren’t corrected or retracted swiftly, the knowledge base becomes increasingly poisoned with bad data.

Honesty, Openness, and Cultural Change in Science

Last month we hosted the first-ever Trial & Error Symposium at the University Museum Utrecht - a day dedicated to rethinking how science deals with failure, uncertainty, and openness.

Researchers, editors, and students came together to discuss everything from publication bias and retractions to the value of communicating uncertainty. What stood out most was the shared belief that science grows stronger when we make space for failed experiments, null results, and revisions.

We also awarded the Trial & Error Award, celebrating the courage to publish scientific failures. Thank you to all our attendants, co-organizers and sponsors!

Does breaking protocol lead to new discoveries?

An undergraduate student researching electricity generation from wood did exactly that. While researching biomass gasification (a method of transforming wood pellets into a gaseous fuel) he occasionally skipped the time-consuming drying phase due to time pressure. But when he analysed the results of the project, the non-drying experiments seem to have had a higher efficiency. Through a clever analogy with a popular snack, and the courage to challenge the details of current models, the student discovered the Popcorn effect.

Reflections on this story, both by the original student Maximilian Roßmann and by Wendy Ross, offer insights into the forces at play. The minor deviation from protocol, the popcorn-analogy that connected seemingly unrelated things, and the knowledge of the topic that connected the dots.

The articles are certainly not advocating for increased sloppiness in conducting science (nor for increasing the time pressure of undergraduate students in hopes for more accidental discoveries). But they show how unexpected outcomes can lead to new understanding, and open gateways to discoveries that are easy to miss.

Have you checked JOTE's latest article on this potential new method for studying brain health?

The article explores a proof-of-concept method to detect blood–brain barrier (BBB)-specific extracellular vesicles (EVs) circulating in peripheral blood. Since the BBB is difficult to study non-invasively, identifying EVs that originate from it could provide a new biomarker for neurovascular health and disease.

The authors outline an experimental approach to isolate and characterize these vesicles, focusing on their potential as indicators of BBB integrity and further brain pathology.

While their findings demonstrate the feasibility of detecting such EVs, they also highlight technical and biological challenges. They distinguish BBB-derived EVs from other endothelial sources and particular standardizing detection methods.

The study concludes that, although preliminary, this approach could pave the way for minimally invasive monitoring of brain health.

Have you read the recent Editorial in Nature regarding disinformation about acetaminophen by American political or “public health” figures?

The editorial warns against the deliberate misuse of scientific uncertainty in public health and policy to mislead or manipulate. It centers on a recent US example: the FDA’s proposal to change the labeling of acetaminophen (paracetamol), warning that prenatal use might be associated with neurological disorders like autism or ADHD. The editorial argues that the FDA’s public messaging overstates the certainty of that link, ignoring contrary evidence and nuances such as publication bias.

The authors contend that when public figures make definitive claims (e.g., “Don’t take Tylenol”) based on contested or unsettled science, they risk “weaponizing” uncertainty. This, in turn, creates ambiguity in political or social leverage. This can erode trust in science, misinform decision-making, and ultimately harm public health outcomes.

The piece calls on scientists, regulators, and communicators to present the full complexity of findings (including uncertainty), resist simplification for rhetorical gains, and avoid portraying debates as binary when they are not.

What do you think about this?

We had a wonderful day at the Trial & Error Award Symposium!

Thank you to everyone who joined us at the University Museum Utrecht.

We were proud to welcome a diverse audience representing many different academic backgrounds. All of our guests contributed to an open atmosphere that fostered critical reflection on positive publication bias, error correction, culture change in research and publishing systems, and the value of sharing failures.

Here are some of the key takeaways from the event:

- Noémie Aubert Bonn’s keynote examined positive publication bias - who is complicit and responsible for it, and how academic fields can move forward.
- Lucie White’s talk on enduring uncertainty and disagreement underscored the importance of understanding why uncertainty persists.
- The presentation by Maximilian Roßmann and Auste Valinciute showed that stereotypes and misconduct often dominate the headlines.

The day was filled with engaging discussions about the trials and errors inherent to academia - topics that are rarely brought to light but deeply important.

A special thank you to our co-organizers and sponsors - De Nieuwe Utrechtse School, Young Academy Twente, Utrecht Young Academy, Museum of Failure, Descartes Centre, GKG Impact Grant, and NWO OS Fund. Your support is always appreciated in hosting such pivotal events.

Have you reflected on how to combat widespread misinformation in your community? This recently published article may have just the suggestion!

The reflection refers to the study ‘Gamified Inoculation Against Misinformation in India: A Randomized Control Trial’. The authors of the reflection discuss the gamified ‘inoculation’ game in rural India, designed to help people resist online misinformation; however, the study failed to produce measurable effects. The reflecting authors argue that two key factors explain this outcome:

-Digital barriers: Many participants had limited experience with smartphones or tablets, reducing their ability to engage with a digitally delivered intervention.

-Cultural-historical factors: The article suggests that people who primarily use ‘everyday concepts’ (concrete, experience-based reasoning) may not benefit from interventions that assume ‘logical concept’ thinking fostered by formal schooling.

To overcome these issues, the authors recommend a strategy called Intervention Mapping; a systematic, step-by-step method to adapt interventions to local contexts, ensuring materials, delivery channels, and reasoning styles align with the target population’s culture and education levels. They also emphasize the value of bottom-up, community-co-designed interventions over simply translating Western digital strategies.

Would you still participate in a study if there was no financial reward?

This study shows how different incentivization strategies—monetary (fixed vs. performance-contingent) and non-monetary (feedback)—affect recruitment, retention, data quality, and participant profiles in Ecological Momentary Assessment (EMA) studies.

What are the key findings?
-Feedback significantly improved recruitment, reduced dropout rates, and enhanced data quality. It also attracted participants with greater interest in research.
-Fixed vs. performance-based incentives had minimal impact on most outcomes; though performance-contingent payment slightly increased prompt responses, the effect wasn’t statistically strong.

What to make of this?
The study highlights the ethical trade-off: while feedback boosts engagement and data quality, it may introduce selection bias, as it appeals more to those already motivated by the topic.
