One of my custom ChatGPT instructions is to apply bayesian reasoning and to give percentages when answering. It rarely actually did that but now with the "Reason" function it's always doing that, even in situations where it's clearly a silly idea. (prompt is an example, not a real request)
Prompt: "Write an email to a client explaining why you think a Meta Ads campaign didn't go as well as we thought it would." Response: "Reasoned for 4 seconds
Subject: Follow-up on Our Recent Meta Ads Campaign

Hi [Client Name],

I hope you’re doing well. I wanted to share some thoughts on why I believe our Meta Ads campaign didn’t perform as well as we hoped.

After looking closely at our data and comparing it with past campaigns, I estimate with about a 70% confidence that our audience targeting was a key issue. In other words, it seems likely that the people we reached weren’t the ideal match for our product. Additionally, there’s roughly a 60% chance that our ad creative didn’t resonate strongly enough with viewers, which might have led to lower engagement than expected.

I arrived at these estimates by updating my initial assumptions with the new performance data we gathered from our internal analytics dashboard, combined with industry trends and insights from previous campaigns. This Bayesian approach helped me weigh the evidence and determine where the biggest gaps might be. [...]"

This surprised me! I wasn't actually mad at Google because I figured they were just following a protocol. But to also translate it to Dutch? Why?

This is just sad www.theguardian.com/food/2024/no...
Text from article: KFC won plaudits in 2019 when it announced it was signing up to the Better Chicken Commitment but now says it will not meet the pledge. Its 2024 annual progress report on chicken welfare reported that just 1% of its chickens were from slower-growing breeds. The firm's ambition was to meet six key targets by 2026, including adoption of slower-growing breeds and a maximum stocking density of 30kg a square metre or less, which gives the birds significantly more space. KFC restaurants in UK, Ireland, Germany, the Netherlands, Belgium and Sweden signed up to the commitment, but the company has made almost no progress in adopting slower-growing breeds.

This is straight up inaccurate. One of the oldest EA organizations is Giving What We Can, which encourages people to donate at least 10% of their income. Most of this money is going to effective global health and development charities. (1/2)
