Summer mayfly swarms are a highly visible reminder of the progress made to improve the health of the #GreatLakes - even if it is sometimes gross to wake up to streets, cars, and everything else covered in a carpet of bugs www.statenews.org/section/the-...

Mayflies' return to Ohio isn't just a nuisance — it's a good sign for Lake Erie

An entire generation grew up without mayflies. But the pesky bug's return this summer points to a healthier Lake Erie .

inspired by @russpoldrack.org's AI policy for his lab, last night I drafted up this AI policy and came up with an initial set of use case suggestions for my lab

General principles
Here are a few key principles that govern our use of AI in scientific work.
AI tools are not necessarily useful. Despite what you might have heard in OpenAI's advertising, using AI tools is the wrong choice for many tasks. Alternative and often more old-fashioned tools will do a better job for quite a few specific things (see this instagram feed for a variety of examples); one should never assume that an AI tool is the default "best thing to try". Moreover, because verifying AI results can be time-consuming, there are plenty of cases where you'll spend less time learning how to do X (i.e., by working on it yourself) rather than having Claude do X and then spending weeks to painstakinly confirm that it worked.
AI usage does not absolve you of your responsibility for your own science. We are responsible for the science that we produce, both from an ethical standpoint and a practical one. Any errors in your work are your responsibility, any security risks caused by AI usage (see below) are your responsiblity, and so on. Just as you must debug the outputs of your analysis code, the outputs of any/all AI usage must be carefully verified.
AI usage requires disclosure. The decision to use (or not use) AI tools for any aspect of the scientific process is one that requires discussion with all leaders of a project. This is both for scientific reasons (i.e., we ourselves must know what our project invovles) and practical ones: many scientific societies and jouranls require the disclosure of AI usage.
AI tools may present security risks. Many commercially available AI tools, especially free ones, do not provide substantive protections regarding inputs provided by users. Put another way, you don't know what will happen to the text, data, images, or anything else you show a third-party AI tool. This may present substantial security risks.
AI is not for scientific writing. Papers are the primary end product of our science. Scientific writing distills our thinkin…

How to handle AI usage
Like many things in our lab, it's best to be vocal. You should always feel free to raise the possibility of AI usage on a project. For any potential use case, chat with your labmates, your collaborators, and Sam about it. Discussion with external-to-lab collaborators can be particularly important given the issue of disclosure, mentioned above; you may not be aware of what AI tools collaborators are using, unless you've asked.
You should also be skeptical of the utility of AI for a specific task (not least because of the billions of dollars being thrown at selling AI subscriptions to universities and other institutions). One thing to consider might be whether the use case is something that would actually be useful for you to master yourself. For example, a common web element that turns up in tons of online experiments would probably be worth your figuring out how to code up from scratch, since you'll use it often in online experiments and figuring it out may help you come up with new ideas for how to design a game. In contrast, an esoteric web element that you'll use for one experiment and never again might be a better fit to farm out to Claude.
With the above General Principles in mind, we do not have any blanket policy about where AI should and shouldn't be used in research, with the clear exception of drafting text for manuscripts, grant proposals, posters, reports, or any other text-based scientific product: AI tools should never be used for writing, i.e., no copying and pasting of text directly from an LLM is appropriate, without explicit discussion and agreement prior to generating the text.
Other use cases are worth considering, however, and should be considered freely. Some good and bad examples follow, based on the principles above (we should populate more examples as they come up).

Some potential examples of AI usage
AI as a cheap web developer. If you're coding up a gamified experiment it can be quite difficult to learn a whole bunch of web development from scratch. Claude will be better at this than you, and that's fine: we are not a web development lab, we're a cognitive science one, so it's not essential that you become a super-proficient dev. Vibe-coding web stuff is a pretty decent use case. (But you must very carefully ensure that whatever AI tools code up for you behave exactly as you expect them to, e.g., if you've vibe-coded a specific form of randomized experiment, you'll need to check that the randomization is being carried out appropriately).
AI as a code reviewer. You might try using an AI tool to figure out why your CSS isn't displaying properly or to help debug code in general. (But you must never provide participant data to a third-party LLM, as this would be a data security risk; and you must always double- and triple-check the tool's output, just as you would with a human code reviewer or if you were trying out tips from Stack Exchange).
AI as a search engine. You might try using an AI tool to discover types of models or analysis approaches that you hadn't heard of before, or to turn up obscure research papers. (But you'll need to verify the output carefully with trusted sources, to ensure accuracy; and you should never, ever treat AI-generated search results as an objective and accurate summary, as they are far from unbiased and are often inaccurate, especially when it comes to scientific questions — try asking Gemini whether music makes you smarter).
AI as a sketch pad. You might try using an AI tool to generate ideas for what to put in a scientific figure, or come up with creative different layouts, which you then use as inspiration for figures you create yourself. (But you should not provide data to an LLM and ask for figures to be produced for you, since this often leads to laughably bad outcomes; it also would not be r…

Some bad examples of AI usage
AI as a data analyst. You should not provide a dataset to an AI tool (this is a security risk) and you should not ask an AI tool to write analysis code for you from scratch. Analyses done without statistical understanding are worse than no analyses at all. While it's OK to use an AI tool to help debug your analysis code, your development as a statistical analyst is part of your scientific development, so it's a bad idea to farm this out.
AI as a literature reviewer. You should not use AI to generate reference lists or summarize whole fields of literature for you. AI tools notoriously cite papers that do not exist, and they recapitulate well-known biases in science (e.g., citing more male authors than female ones).
AI as an illustrator. We are fundamentally opposed to the practice of AI models appropriating human artists' work to produce generative imagery and so we do not support its use for scientific work. The reputational risks associated with embarrassing errors in generative imagery are also substantial. We are lucky to have grants available to us that can be used to pay illustrators and graphic designers for work, and we regularly hire folks like this. Talk to Sam if you have a design need on a project that you'd like us to fund; it's a much better call than using AI.

I just had that conversation earlier this week. The college dean is deciding if they will (dis)continue the bioinformatics training program for grad students. An argument for discontinuation is that students will use GenAI to help them code, so they don’t need to learn bioinformatics.

Erin Grievances@erinbartram.bsky.social · 5mo ago

The danger to my job from AI isn't that AI can do my job, it's that my job is made even more precarious by the way AI is shaping ideas of the value of work. It can't do my job, but it can be part of convincing people (incorrectly) that my job isn't necessary.
