Quote

"Wherever there is judgement, there is noise, and even when we know this, there's more of it than we think"

Variability is a good thing in any endeavour that allows you to select the better option.
But variability in the absence of being able to choose, results in a sheer loss of accuracy.

Noise, at least in psychology, is "unwanted variability".

2

When you take multiple independent judgements and average them, you eliminate noise.
The more independent judgements, the more accurate it is.

But when we don't have the luxury of getting more people's views, asking each individual or even yourself the same questions across different time points can lead to better results.

Your own average response is often better than any individual response, because you've often asked yourself how your previous judgements could be wrong.

In some cases, machines can make better judgements than humans because it will always return the same output for any given input, it's without noise.
Despite this, our psychological irrationality leads to people's threshold of accuracy for a machine being significantly higher than that of other humans.

Resulting in people choosing humans over machines despite knowing machines would lead to statistically better outcomes.
