No son pocas las personas que cada vez que le preguntan algo a chat-GPT (o cualquier modelo de lenguaje) sienten como si realmente estuviesen "hablando" con otra persona. Incluso, hay gente que va más allá, y hablan de como estos sistemas parecen ser "conscientes".
¿Pero, es tan así?
Hilo va!!
Our brains are powerful predictors influenced by personal experiences and societal norms, leading to biased perceptions. This “affective realism” shapes our views, creating stereotypes that distort reality. These biases affect social interactions, triggering in-group connections.
MSF hacemos un llamamiento a que se proteja en todo momento a la población civil, los hospitales, las instalaciones sanitarias y otras infraestructuras esenciales.

Excited to share our new paper:
We uncover a locus coeruleus→amygdala circuit linking β-adrenergic signaling to transcription regulation in defined amygdala cells during memory reconsolidation—+ stress or elevated noradrenergic signaling at recall can strengthen memory.

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!

They won't start with banning birth control. First they'll lie about it. Then dictate who can prescribe it, use it, fund it, in what forms, and for how long. Suddenly, your doctor won't call you back. I know this is what they'll do because it's what they're doing to transgender healthcare right now.
How and why does cognition vary so greatly between individuals and species? In @natrevbiodiv.nature.com, we propose the "Predatory Intelligence Hypothesis" which posits that the cognitive challenges associated with predator–prey interactions drive a cognitive co-evolutionary arms race
