Thank you to @anahidmodrek.bsky.social for visiting with my FAQs about Life seminar this week! We read her fabulous work with @tanialombrozo.bsky.social showing positive effects of explaining on test scores & appreciated chatting with her about this research: onlinelibrary.wiley.com/doi/pdf/10.1...

In a new post for Character & Context (@spspnews.bsky.social), I dive into my work with @tanialombrozo.bsky.social on how jargon shapes scientific understanding. Check it out here!

In lots of cases that's enough to get by in the world: it tells us what search terms to use, maybe who to ask. But that doesn't mean we infer the meaning of the jargon or connect it deeply with what we already believe about what's being explained.

I don't think it's *only* a credibility cue - we did find that our participants judged the explanations with jargon to have come from a more expert source, but that didn't fully explain the interaction with explanation completeness. One possibility is that jargon is like an explanation placeholder..

I suspect that there are boundary conditions on these effects (e.g., if the source isn't trusted for other reasons), but we didn't test that in this set of studies.

We did! We consistently found that jargon increased the perceived expertise of the source for both poor (nearly circular) and good explanations, and in one study made participants judge the explanations more likely to be true...

In this example the jargon was made up! In some of our studies we used real jargon, and in other studies we used invented jargon (so that we could be sure the jargon was not conveying any additional content beyond the presence of jargon itself). But "candy triboluminescence" is a real phenomenon!

How laypeople evaluate scientific explanations containing jargon - Nature Human Behaviour Cruz and Lombrozo examine how laypeople make sense of scientific explanations and find that although jargon reduces understanding, for short explanations, jargon makes the explanation more satisfying.

This project was a collaboration with @cruzf.bsky.social, who visited my lab at Princeton as an international PhD student. A reminder that science is richer and better when we work together - it makes the US richer and better, too.

This doesn't imply that people are stupidly bamboozled by jargon - in many cases, jargon can be a good cue to expertise and it can offer a pointer to expert knowledge. But in everyday cases (like short science explanations in headlines), jargon can create an inflated sense of satisfaction...

We also found that we could reduce the elevated sense of explanation quality engendered by jargon by having people *try to generate their own explanations.* When they did so, they better appreciated the gaps in their own understanding, and that they weren't filled by jargon.

But when explanations are more complete, adding jargon decreases comprehensibility without increasing satisfaction. There aren't obvious gaps for the jargon to fill. We found this across a range of explanations, some with real jargon and some with made-up jargon (like the example)...

"Have you ever noticed that crunching candy can sometimes release a spark of light? That's because, *when candy is crushed*, this can result in visible light" vs *when candy plotens are crushed*. This explanation was judged more satisfying when it contained the extra jargon!

When people receive poor (nearly circular) explanations with jargon, they assume the jargon fills explanatory gaps. So jargon makes the explanation seem more complete and more satisfying. Compare the following two examples:

Consistent with prior work, we find that jargon typically makes explanations seem less *comprehensible* to laypeople. Yet, sometimes, it can also make explanations seem *more explanatory.* Across 9 experiments with over 6K participants, we reveal why...

Laypeople often learn about science from expert explanations & those explanations often contain JARGON. Does jargon make explanations better or worse? In a paper out today in Nature Human Behaviour, @cruzf.bsky.social and I find that jargon can support illusions of understanding...

President Trump’s FY26 budget for #NSF will slash funding for the agency by 56.9% and funding for Social, Behavioral, and Economic sciences by 67.6%

These cuts will end US STEM leadership, weaken national security, and set-back individual prosperity and well-being.

Why do people engage in collective actions, even when they believe their actions won't make a difference?

Based on evidence from the 2024 election and a hypothetical election, we find that *moral* responsibility, not causal, drives voting

Unfortunately, the NSF grant that supports our work has been terminated. This is a setback, but our mission has not changed. We will continue to work hard on making cognitive science a more inclusive field. Stay tuned for upcoming events.

Are you interested in research experience before applying to PhD programs? Or just want to learn more about cognitive science? Consider joining my lab as a lab manager (joint w/the Griffiths Lab). We will begin reviewing applications one week from today: cognition.princeton.edu/news/2025/op...
