PNAS vs Science Advances: Which Broad-Scope Journal for Your Paper?

PNAS requires a 120-word Significance Statement with every submission. This isn't filler. It forces you to articulate why your work matters to scientists outside your field. Papers that do this well tend to succeed. Papers that can't explain their significance in plain language tend to fail.

PNAS editorial identity:

• Interdisciplinary work that bridges fields is the clearest fit
• Methodologically rigorous studies with careful statistics
• Social sciences (economics, psychology, political science) are welcome here. PNAS is one of the few high-IF venues for social science research
• The 2022 reforms eliminated the Contributed track (NAS members selecting their own reviewers), making the playing field level for all authors
• Board of Reviewing Editors members identify suitable reviewers; they don't review papers themselves

What PNAS rewards:

• Clear Significance Statements that a non-specialist can understand
• Rigorous, large-scale investigations with strong supplementary materials
• Work that has implications across multiple scientific disciplines
• Rigorous methodology and appropriate statistical analysis

Science Advances is known for fast decisions and editorial flexibility. Where PNAS has a 45-day median to first decision, Science Advances often responds within 1-4 weeks. The editors are working scientists, not professional editors, which gives the journal a different review culture.

Science Advances editorial identity:

• Speed matters. Fast decisions, fast publication
• Working-scientist editors who understand your field from the inside
• Flexible formatting. No strict word limit. More figures welcome
• About 80% of submissions come directly, not through Science transfers
• Fully open access, which matters for funder mandates and global readership

What Science Advances rewards:

• Strong science that benefits from open access distribution
• Papers that need longer format than Science can accommodate
• Work at the intersection of science and societal impact
• Solid multidisciplinary research across all fields

The difference is $3,620 per paper if you're comparing OA to OA. And PNAS gives you the option to publish at $0 behind the subscription paywall, Science Advances does not. For budget-constrained labs publishing 3-4 papers per year at this tier, the cost difference between PNAS ($0-$1,830 per paper) and Science Advances ($5,450 per paper) is $10,000-$20,000 annually.

This cost advantage disappears if your funder mandates gold OA and your institution has an AAAS agreement. But for most researchers, PNAS is significantly cheaper.

PNAS review:

1. Editor assignment (Board of Reviewing Editors)
2. Reviewer identification (2-3 reviewers, ~45 days)
3. Decision (accept, revise, reject)
4. Revision turnaround varies
5. Total: typically 3-6 months to acceptance

Science Advances review:

1. Working-scientist editor evaluates (1-4 weeks)
2. If sent to review: 2-3 reviewers (~4-6 weeks)
3. Decision
4. Total: typically 2-4 months to acceptance

Both journals are well-respected, but perception varies by field:

• In biology and biomedical sciences: PNAS carries strong historical prestige. Some view it as the next tier below CNS (Cell/Nature/Science).

• In physical sciences and engineering: Both are well-regarded. Science Advances' connection to AAAS/Science carries weight.

• In social sciences: PNAS is clearly the stronger choice. It's one of the most-cited venues for economics, psychology, and political science research.

• In interdisciplinary work: PNAS edges ahead due to its explicit interdisciplinary mission, the required Significance Statement, and broad NAS readership. The Significance Statement format forces authors to articulate cross-field relevance, which naturally attracts interdisciplinary work.

PNAS is the only top-tier journal that requires a formal 120-word Significance Statement with every submission. This statement is the first thing the Board of Reviewing Editors member reads after the abstract. It must explain the work's importance to a non-specialist NAS audience in plain language.

This requirement is both a filter and a feature. Papers that can articulate their significance to a broad audience tend to succeed at PNAS. Papers that can't, either because the work is too narrow or because the authors haven't thought about broader implications, tend to fail.

If you can write a compelling 120-word statement that makes a neuroscientist care about your chemistry paper (or vice versa), PNAS is worth submitting to. If the significance only makes sense to specialists in your exact subfield, Science Advances or a specialty journal may be a better fit.

Before submitting, a PNAS vs. Science Advances significance framing check can catch the fit, framing, and methodology gaps that editors screen for on first read.

The 2022 reforms that eliminated the Contributed track fundamentally changed PNAS. Previously, NAS members could submit their own work and select their own reviewers, a system that gave connected PIs an advantage. Now all submissions enter a single Direct Submission pathway with standard editorial peer review.

This means: if you're not an NAS member, PNAS is now a fairer playing field than it was before 2022. If you are an NAS member, you still get a guarantee of external review for one submission per year (similar to JCI's ASCI member benefit), but you no longer control reviewer selection. The result is a more meritocratic PNAS that's worth considering for any researcher with a strong, significant paper.

A PNAS Significance Statement framing check can assess whether your Significance Statement framing is strong enough for PNAS's editorial bar.
