In 25-Country Survey, Americans Especially Likely To View Fellow Citizens as Morally Bad Across 25 countries, Americans are the most likely to see the morality and ethics of people in their country as somewhat or very bad.

A Pew Research poll of 20 countries asked if residents thought their fellow citizens had bad ethics & morality. Only Americans were more likely to think that.

Also PS: Even before LLMs, I know software hiring managers who were no longer requiring coding interviews, because people were hiring others to do the coding over Zoom. In the 21st century, the only way to know someone understands a concept is to listen to him/her in person explaining it.

I want to take you back, for a moment, to 2020. We are at the beginning of the pandemic and many of us are working remotely. I don't remember this time particularly fondly--this was pre COVID-19 vaccines, and there was a lot of rhetoric around how the virus had come from China. 🧡

I have just come across a case of academic fraud -- a paper with citations to non-existing papers. I know that this is happening elsewhere but I am furious. Too many people -- editors & referees -- put in too much time (often unpaid) trying to ensure quality for this to be even remotely acceptable.

Music is not a universal language β€” but it can bring us together when words fail Societies, animals and even machines have music in common. Our varied experiences of it might tell us about the origins of language.

"Western listeners usually find music in major keys happy and in minor keys sad. By contrast, Papua New Guinean listeners felt no difference in happiness between major and minor keys, and Pakistani listeners found minor keys happier than major ones" www.nature.com/articles/d41...

Online Studies
Psychological Science requires that authors who use samples from online data collection include a statement in the Method section explicitly addressing their approach to preventing and detecting automated or AI-generated responses.

Rationale

As large language models and other generative AI tools become more accessible, the risk of data contamination by non-human respondents has increased dramatically in research. Psychological science (and the social sciences generally) is particularly susceptible to this issue given its growing reliance on online data collection. Preventing automated responses during data collection and detecting them afterward often involve methodological trade-offs. For instance, technical barriers that aim to prevent LLM use (e.g., blocking copy-pasting functionalities) may eliminate behavioral indicators needed for detection (e.g., pasting rather than typing). This policy aims to enhance transparency and reproducibility of reported results by requiring authors to articulate their approach across both prevention and detection dimensions, enabling readers and reviewers to assess the likelihood of reported data being influenced by automated responses.

Scope

This policy applies to any submission with at least one study that includes data collected online without direct human supervision (e.g., via crowdsourcing platforms, student participants who complete the study online, online recruitment ads, or remote survey distribution tools).

Required Reporting

Authors must include in the Methods section either:

A statement confirming that procedures were in place to prevent and/or detect and exclude automated or AI-generated responses, including a description of those procedures (e.g., explicit participant instructions against LLM use, disabled copy–paste functionality, CAPTCHA use, IP filtering, consistency checks, attention checks, adversarial prompting) as well as the types of automated responses that these procedures are suitable …

Maybe of interest: The submission guidelines of Psychological Science now demand an explicit statement on measures taken to reduce the risk of AI-generated responses for all online studies!

Perspective:
Open-ended responses can improve ESM data by grounding it in real-world experiences and phenomena as they are experienced in everyday life. Handbooks and guidelines on ESM should include sections on collecting and analyzing open-ended text items.

A university education

"The characteristic gift of the university is the gift of an interval. Here is an opportunity for you to put aside the hot allegiances of youth without the  necessity of at once acquiring new loyalties to take their place. Here is a break in the tyrannical course of irreperable events; a period in which to look around upon the world and upon oneself without the sense of an enemy at one's back or the insistent pressure to make up one's mind; a moment in which to taste the mystery without the necessity of seeking a solution. And all this, not in an intellectual vacuum, but surrounded by all the inherited learnings and literature and experience of our civilisation."

Michael Oakeshott, quoted in The Observer
