A Cornell University study found that people who go against their better judgment feel greater feelings of control and culpalibility, even if they received input from an adviser. This effect may extend beyond small decisions to major life choices.
The Finnish Institute for Health and Welfare has published a governance model for the wellbeing economy, which aims to balance social, economic, and ecological sustainability in national-level decision-making. The model proposes using citizens' consultation processes and long-term wellbeing targets to guide government programs.
Researchers discovered that trying to make ourselves happier actually makes us less happy by draining our ability to use self-control and willpower. This 'happiness paradox' is caused by mentally exhausting efforts to regulate thoughts, emotions, and behaviors.
Researchers used fMRI to investigate how the brain processes ambiguous messages, finding that more complex tasks engage multiple brain regions. The study reveals that understanding others' thoughts and emotions contributes to successful performance, with greater flexibility in reasoning.
Research from the University of Kent found that socially dominant individuals are more confident in their decisions, debunking the notion that confidence equals competence. The study, published in Personality and Individual Differences, used two-choice statistical learning tasks to assess participants' performance.
