Designing AI for Disruptive Science

Asimov Press • 438 implied HN points • 23 Mar 26
🔬 Science Metascience
  1. Scaling AI and more data mainly improves prediction inside current frameworks, but it won’t by itself create the simple, reframing ideas that drive paradigm shifts. This risks a kind of “hypernormal science” where detail increases but true conceptual breakthroughs become rarer.
  2. Major scientific revolutions come from simple unifying principles, cross-domain analogies, outsider perspectives, or new sensory grounding, not just better curve‑fitting. To foster breakthroughs, AI must be built to search for simplicity, draw structural analogies, and be grounded beyond narrow benchmarks.
  3. Designing disruptive science requires deliberate changes to both AI and research institutions: run controlled agent experiments, protect small risky teams, and change incentives so novel, risky reframings are discovered and rewarded. Without that metascientific engineering, AI will mostly accelerate conventional work rather than spark revolutions.

things will have to change

Never Met a Science • 188 implied HN points • 15 Jan 26
🔬 Science Metascience
  1. AI is now powerful enough to reshape how research is produced, and academic institutions must adapt quickly or be overwhelmed by a flood of AI-assisted work.
  2. AI offers clear benefits like automated replication and more frequent updating of knowledge, but we need institutional safeguards about ownership, verification, and corporate control of the tools.
  3. The role of scholars should shift toward curating and filtering knowledge and maintaining deep expertise, supported by metascientific reforms that preserve epistemic authority and make inductive approaches credible.

Peer Review 2027

🔬 Science Metascience
  1. Forbidding researchers from using LLMs is unstable and impractical because detection is unreliable and incentives to defect are strong, so allow and encourage AI use for concrete, practical research tasks.
  2. Peer review must be strengthened: shift resources toward human evaluation so people remain responsible for judgement and "taste," with reviewers held to different standards and supported by tools (including LLMs for checks).
  3. Institutional reforms and data are needed to manage higher submission volumes: introduce frictions like submission fees or caps where appropriate and build metascientific data streams to monitor uptake and adapt policies.

The Economy of Knowing

The Good Science Project • 167 implied HN points • 23 Dec 25
🔬 Science Metascience
  1. Metascience needs a clear micro vs. macro distinction: micro focuses on individual scientists’ beliefs, trust, and behaviors, while macro covers institutions, funding, and governance.
  2. Reforms often fail when they operate at only one level because individuals respond to incentives in predictable ways, producing unintended outcomes like gaming rules or self‑censoring risky work.
  3. Fixing science requires a full‑stack approach that designs policies to change both institutional incentives and the everyday experience of researchers, accounting for the feedback loops between the two.

Back and Forth on the Value of Replication

The Good Science Project • 48 implied HN points • 29 Jan 26
🔬 Science Metascience
  1. Replicating studies early usually gives much bigger returns because it can stop entire lines of follow-on work from chasing a wrong result, though some older papers that still drive current research can also be worth replicating.
  2. Citation counts are an imperfect measure of influence, and once a paper's findings are deeply embedded across many follow-on studies, a single replication may not undo that influence—so sometimes it's higher impact to replicate key descendant papers instead of only the original.
  3. The impact of replication can be increased by changing incentives and communication: funders and journals can publicize replication results, link them to original papers, and adjust funding or citation expectations to make replications matter more.

  1. Increasing population growth is crucial for economic and technological progress
  2. People have increasing returns and can drive economic growth by sharing ideas
  3. Population growth is fundamental for economic growth and technological progress based on empirical evidence

Metascience at the NIH

The Good Science Project • 59 implied HN points • 05 Aug 25
🔬 Science Metascience
  1. The NIH is looking to limit high article processing charges for open-access journals. This is important because some journals ask for really high fees that can take away from research funding.
  2. The NIH is working to reduce bureaucracy that slows down research. Researchers spend a lot of time on paperwork, which could be better spent on their actual science work.
  3. There’s a focus on funding more replication experiments in science. This is key because it helps check if important research findings are true and not based on mistakes or fraud.

Metascience Manquè

Never Met a Science • 50 implied HN points • 17 Jul 25
🔬 Science Metascience
  1. Metascience is struggling because it's too focused on just replicating studies, rather than exploring deeper questions about what science is and how it could improve. This limits its potential.
  2. Communication between different scientific fields can be helpful, but it often leads to misunderstandings about methods and goals. This can result in a distorted view of what science really is.
  3. To make science better, we need to rethink how we share knowledge. Relying only on traditional formats like PDFs isn't working anymore. More flexible and collaborative ways of sharing research could lead to better science.

Science and Its Discontents

Holodoxa • 139 implied HN points • 29 Mar 23
🔬 Science Metascience
  1. Current systems for basic scientific research have weaknesses in terms of funding, publication incentives, and impact evaluation. Scientists often spend less time on actual research due to grant application efforts, and research impact is measured ineffectively.
  2. Systemic issues in research science include inefficiencies, triviality, and misaligned incentives, leading to concerns about technological stagnation and economic growth. The replication crisis is a notable problem, affecting various fields due to lack of reproducibility.
  3. Metascience, analyzing and improving scientific methodology, offers hope for enhancing the quality and efficiency of research. It encourages transparency, awareness of limitations, and informed decision-making by scientists, policymakers, and funders, despite facing obstacles in adoption.

An Oral History Interview with ARIA CEO Ilan Gur

The Good Science Project • 22 implied HN points • 13 Jun 25
🔬 Science Metascience
  1. ARIA aims to fund bold projects that create entirely new technologies and industries, not just improve existing ones. They want to be catalysts for major shifts in science and technology.
  2. The role of program directors at ARIA is crucial. They are chosen for their unique visions and are encouraged to pursue high-risk, innovative ideas, even if those ideas face skepticism from others.
  3. Funding is focused on exploring 'opportunity spaces' rather than specific projects. ARIA believes in investing in diverse approaches to find breakthrough solutions, allowing them to adapt and pivot based on what they learn.

A writing fellowship on scientific progress

The Works in Progress Newsletter • 25 implied HN points • 11 Feb 25
🔬 Science Metascience
  1. There is a six-month writing fellowship where writers can create articles about scientific progress. It's a great chance for those interested in topics like biotech or the history of science.
  2. Writers in the fellowship will get help from experienced mentors and editors to improve their work. They will also receive a stipend of $1,500 per month for completing their writing.
  3. It's important for applicants to have a blog or previous writing experience. The fellowship encourages original thinking and aims to support writers looking to share their unique ideas.
