Some media are reporting that our recent study (nature.com/articles/s41598-0…) shows that pit bulls are especially likely to become aggressive if they are exposed to early life stress. Simply not true.
So why is the media reporting that pit bulls are especially likely to become aggressive if they experience trauma? One possibility: hallucinations from LLMs that generate initial drafts of the news articles. AI reflects the biases of our culture as a whole.
If you have a rescue dog, you might have the sense that stressful experiences can impact dogs' behavior later in life. Well, we just did the largest study ever on this topic. Open access! nature.com/articles/s41598-0…
Why is this important? If we can identify the genes and pathways underlying this risk and resilience, we might be able to develop targeted interventions. We are already analyzing the dogs' DNA samples and MRI scans!

Hey @colossal. Wanna scan your dire wolves' brains? My lab at Harvard University does non-invasive MRI scans in dogs, foxes, and more!
Using non-invasive MRI, we found a pathway in dog brains that predicts receptive vocabulary size. It’s left-lateralized & connects regions that produce and perceive vocal communication. A convergently evolved arcuate fasciculis? Read at @CurrentBiology: sciencedirect.com/science/ar…

ALT The image shows a white matter path in the dog brain connecting vocal premotor region XC to temporal auditory regions rESG and pESG. A bar graph shows that the tract is significantly larger in the left hemisphere. Scatterplots show that the tract predicts the receptive vocabulary size of individual dogs.
I emailed Dr. Trut as a no-name grad student asking if I could do MRI research with her foxes. She didn’t write me off & 15 years later I have a lab at Harvard continuing to study the amazing animals she helped create. She made an impact in science & my life. Thank you, Dr. Trut.
