A normal distribution will average to 0, with enough samples. The center and spread is important, since individual measurements can be considered a random sampling within that distribution. But, this is overly simplifying things, and assume random error, which AI systems often don't exhibit.

It appears this is moot, because the quote did not reflect the actual value or method used.

The distribution of human temperature levels is already known, you could just give the average temp as every guess and get maybe 1.5 F average error.

My point is, you can’t really get 0.44F avg error unless it’s predictive. The “std dev” of abs(reality - model) is too high
