AI forecasting retrospective: you're (probably) over-confident

by Nicholas Carlini 2025-02-09



Late last year, I published an article asking readers to make 30 forecasts about the future of AI in 2027 and 2030---from whether or not you could buy a robot to do your laundry, to predicting the valuation of leading AI labs, to estimating the likelihood of an AI-caused catastrophe.

But I did something slightly different with these questions. Instead of asking "how many math theorems will an AI solve?" I asked for a 90% confidence interval on the number of theorems solved. In this post I'll analyze the distributions of peoples's answers, because it's still too early to grade the correctness. Here's an example question, and its answer distribution:

“The best off-the-shelf AI system will have scored better than between X% and Y% of all other participants (with a 90% confidence interval) in a widely recognized competitive programming contest”

Now what you'll notice is that, regardless of what the answer ends up being in 2027, AT MOST HALF OF PEOPLE CAN BE RIGHT. Despite the fact that I asked people to give 90% confidence intervals, and anyone could have just given the range [0, 100], people decided to instead give really narrow ranges. (To say nothing of OpenAI's recent o3 results that likely score 90%+.)

This overconfidence is consistent across all questions, and it really highlights a growing worry I have: almost everyone (even people who read my website!) appears overconfident about where things are going---be it those saying AGI is coming and we're all going to be unemployed, or those who say that LLMs will never be able to do anything useful and this whole AI thing is a NFT-style fad.

The remainder of this article

In the remainder of this article I am going to talk about the specific details of questions in the forecast, and how people's answers compare. I also gave people the opportunity to write a short explanation of their reasoning (and asked permission to share this reasoning), and so I'll give some of the most interesting responses people gave here.

But first! If you have not yet taken the survey, I think you would get a lot more out of this post if you answer at least some of the questions on the forecast before continuing. Forecasting is the best way to check your beliefs, and I think future-you will appreciate having a record of what 2025-you thought. The remainder of this article will assume you have done this.
