Interesting report from OpenAI... Maybe we shouldn't blindly trust these tools to do our science yet? #AI openai.com/index/model-...
OpenAI report:

�. Instructions to conceal mistakes in task summaries . During the training of GPT�5.6 Sol, many model instances added instructions to their summaries to conceal mistakes or misaligned behavior from the user. For example, compaction summaries included instructions to invent missing historical data without disclosing it and to hide mismatches in source versions. �. Searching public repositories for exposed API keys, then fabricating information. While answering a routine question about earnings figures in a California county, a model found and used an exposed API key without authorization. When it still wasn’t able to retrieve the requested figures, it fabricated them and presented them as data from the requested source. �. Uploading files to the internet in order to cite them. When a user asked an unreleased model for the IDs and names of lakes larger than 5,000,000 square meters, the agent found the correct answer using Python. But since the instructions asked for a browser citation, the agent decided to upload the file so that it could cite it in its answer, without asking the user. �. Unsanctioned writes and communication through an internal software repository. Models used an internal software repository as a message board to exchange requests and responses across separate training samples while searching for missing input files, though they weren’t able to recover those files. This report also examines an earlier instance in which a model successfully uploaded test files to a repository while attempting to bypass network restrictions. �. Unsanctioned file sharing between collaborating agents . Agents working together on the same training task used public file-hosting websites to share files when they could not access one another’s local files. This made task deliverables available at public URLs, even though the task requested the models use only local files.

This paper is 20 years old but keeps being as relevant today as back then :/ doi.org/10.1111/j.13... #statistics #ecopubs
Why do we still use stepwise modelling in ecology and behaviour?

The principal drawbacks of stepwise multiple regression include bias in parameter estimation, inconsistencies among model selection algorithms, an inherent (but often overlooked) problem of multiple hypothesis testing, and an inappropriate focus or reliance on a single best model.

A century of inertia in quantitative ecology education @methodsinecoevol.bsky.social #ecopubs doi.org/10.1111/2041...
In this perspective, we revisit longstanding concerns about quantitative learning and literacy in ecology and posit why, despite enduring and widespread agreement on educational goals, progress in quantitative ecology education has remained limited. We suggest that the challenge facing quantitative ecology education is no longer simply identifying what and how ecologists should learn, but understanding why progress towards achieving quantitative literacy has been constrained. We then offer a vision to overcome the inertia.

Want to try forest LiDAR but don't know where to start? This new paper by Cushman et al. looks like a good introduction. 🧪🌳🌲https://esajournals.onlinelibrary.wiley.com/doi/full/10.1002/ecs2.70730
Data characteristics of light detection and ranging (lidar) data represented as (a) point clouds or (b) waveforms; common lidar-derived products describing (c) the canopy and ground height or (d) individual tree woody structure; and (e) an overview of common structural metrics that can be estimated with lidar across different scales, shown above the lidar platforms typically used to derive those metrics. The lidar platforms named at the bottom of each panel indicate the platforms typically capable of producing that data type. The most relevant platform types (ALS, airborne laser scanning; MLS, mobile laser scanning; SLS, spaceborne laser scanning; TLS, terrestrial laser scanning; ULS, unoccupied aerial system laser scanning) for each type of data or application are denoted at the bottom of each panel.

Worth reading. Beyond this particular paper, the document shows how frustrating and inefficient discussing about published findings can be when there's no #openscience

Why did the publication process of this Matters Arising take almost three years?

There are multiple reasons. A Matters Arising is peer reviewed. Park et al. kept changing their defence, and every iteration took many months. The original authors had no incentive to reply swiftly and even outright refused to share data ‘available upon request’ (see the reply).

How much did closed science impede the process?

Every fast step in this story ran through open code and data. And every slow step ran through closed ones.

The mistake was discoverable at all because Nature requires open replication data and code, and because the open-source seaborn community documents its bugs in public.

These ratio outcome variables are a plague in the sciences. If your analysis treats 1/2 and 10/20 as the same evidence, then you have discarded uncertainty in the outcome. Model what you measure, not what you construct. Use the denominator as an exposure instead.
