A new study found that consumers who lie during a service encounter are more satisfied when they get what they want. Lying is perceived as hard work, resulting in fewer mental resources for other tasks, including updating expectations about the conversation's progress. This leads to stronger reactions to outcomes.
A pharmacist-led, information technology-based intervention reduced prescribing errors by 42% in primary care, with significant reductions in specific medication errors. The intervention was found to be cheap and easy to implement, costing $75 per error avoided, making it a cost-effective solution for reducing medication errors.

The onset of the cold period is believed to have been caused by an unusual sea ice-ocean feedback system originating in the North Atlantic Ocean.
A new study published in Psychological Science found that individuals who feel powerful tend to overestimate their own height. This means that those with more power perceive themselves as taller than their actual physical stature. Conversely, people with less power may see others and objects as larger compared to them.
New research reveals that toddlers don't respond to their own voice in the same way as adults, requiring alternative strategies for controlling speech production. Four-year-olds are shown to monitor their speech similarly to adults, while two-year-olds do not, hinting at a possible reliance on caregivers' feedback.

The system provided continual feedback to drivers who needed it most, leading to a significant improvement in their driving behavior.
Unaccounted ecosystem feedbacks could significantly impact future climate change due to increased greenhouse gas emissions from wetlands, soils, and fires. These biogeochemical cycles may counteract the cooling effect of carbon uptake by plants, contributing to increased warming.
A recent study published in Psychological Science found that students who expected to receive grades quickly performed better than those who anticipated delays. This counterintuitive result may be due to the threat of disappointment being more prominent for early expectants, leading them to perform better as a result. The study has imp...
A 15-year French hospital program using surveillance, precautions, training, and feedback led to a 35% decrease in methicillin-resistant Staphylococcus aureus (MRSA) burden. The program was most effective in intensive care units, with a 59% decline in MRSA cases.
Scientists find that Arctic sea ice loss is driven by the formation of arches, which block flow and lead to increased ice loss. In Mars, solar wind pulses contribute to atmospheric escape, with bursts occurring in association with corotating interaction regions.
