It might not prevent initial wrongdoings, but guilt allows humans to judge their own prior judgments as harmful and prevents them from happening again. The internal distress caused by feelings of guilt often—but not always—results in the person taking on some kind of penance to relieve themselves from internal turmoil. This might be something as simple as admitting their wrongdoing to others and taking on a slight stigma of someone who is morally corrupt. This upfront cost might be initially painful, but can relieve further guilt and lead to better cooperation for the group in the future. https://techxplore.com/news/2025-07-ai-evolve-guilt-social-environments.html Computer Sciences Wed, 30 Jul 2025 12:23:58 EDT news673097029 Brace yourself for a new source of online disinformation: AIPasta. https://techxplore.com/news/2025-07-aipasta-ai-paraphrase-disinformation.html Machine learning & AI Tue, 22 Jul 2025 15:31:13 EDT news672417070 Major social media platforms are enabling and profiting from misinformation around extreme weather events, endangering lives and impeding emergency response efforts, a research group said Tuesday. https://techxplore.com/news/2025-07-extreme-weather-misinformation.html Internet Tue, 22 Jul 2025 13:40:08 EDT news672409982 With so many people using devices that can be connected to the internet, reliably securing wireless communications and protecting the data they are exchanging is of growing importance.
