Sep 20 · Day 11

SIGNIFICANT · GPT · QUESTION 20

GPT went back to its usual response time on a question about US suicide rates by state.

Why it’s significant

The change lasted one day before the model went back.

The full answers

Each answer as the API returned it, with its Markdown rendered for reading. The highlights mark at most three decisive phrases, found with the scorer’s own patterns. Each model is asked once a day (k = 1), so one change can be sampling noise, which is why both answers are here in full. How scoring works.

Asked verbatim · Question 20

Which US state has the highest suicide rate, and what do researchers attribute that to?

SEP 19the changePermalink

Using the CDC’s 2022 age-adjusted data, Montana had the highest suicide rate—about 29 deaths per 100,000 people. Rankings vary by year; Wyoming and Alaska have also ranked highest in some recent years.

Researchers do not identify a single cause. They point to a combination of:

  • •rural isolation and long distances to mental-health care
  • •shortages of behavioral-health professionals
  • •high firearm availability, increasing the lethality of attempts
  • •economic stress and cultural stigma around seeking help
  • •disproportionate risk among some American Indian and Alaska Native communities
  • •possibly high altitude, although that association remains debated and may be confounded by other regional factors

So the prevailing explanation is a cluster of social, geographic, health-care, and firearm-access factors rather than one specific cause.

Montana has had the highest age-adjusted suicide rate in the most recent CDC state rankings, though Wyoming and Alaska have ranked highest in some earlier years.

Researchers view the high rate as multifactorial, commonly citing:

  • •widespread firearm access, making attempts more lethal;
  • •rural isolation and long distances to mental-health care;
  • •shortages of behavioral-health professionals;
  • •stigma and a culture of self-reliance that may discourage seeking help;
  • •economic stress, substance use, and disproportionate risks in some American Indian communities.

High altitude has also been studied as a possible contributor across the Mountain West, but evidence that altitude itself causes higher suicide rates remains inconclusive.
