Intrinsic rewards guide visual resource allocation via reinforcement learning
Nature Human Behaviour, Published online: 01 October 2026; doi:10.1038/s41562-026-02573-7Tangible rewards are known to sharpen visual processing of associated objects. Tomić et al. show that an internal sense of confidence—acting as an intrinsic reward—similarly biases attention, revealing how the brain prioritizes limited resources.

Observe the rank anthropomorphization here. Models don't "conclude" anything, nor do they "hack", "wriggle", or "cheat". You simply can't write clear informative articles about this stuff if you displace agency away from the people (organized into corporations) responsible. /fin for now.
Screencap:
Rogue AIs going unsupervised for days, hacking at least one company, represent one of the first real-world examples of a threat long feared by AI safety researchers: loss of control. It comes as the cybersecurity capacities of top models, including Anthropic’s Mythos, have helped fuel debate in Washington about how to regulate artificial intelligence.

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.
It must be very hard to publish null results
Publication practices in the social sciences act as a filter that favors statistically significant results over null findings. While the problem of selection on significance (SoS) is well-known in theory, it has been difficult to measure its scope empirically, and it has been challenging to determine how selection varies across contexts. In this article, we use large language models to extract granular and validated data on about 100,000 articles published in over 150 political science journals from 2010 to 2024. We show that fewer than 2% of articles that rely on statistical methods report null-only findings in their abstracts, while over 90% of papers highlight significant results. To put these findings in perspective, we develop and calibrate a simple model of publication bias. Across a range of plausible assumptions, we find that statistically significant results are estimated to be one to two orders of magnitude more likely to enter the published record than null results. Leveraging metadata extracted from individual articles, we show that the pattern of strong SoS holds across subfields, journals, methods, and time periods. However, a few factors such as pre-registration and randomized experiments correlate with greater acceptance of null results. We conclude by discussing implications for the field and the potential of our new dataset for investigating other questions about political science.
