> For each article ChatGPT estimates:
> Magnitude: how big was the effect;
> Scale: how many people the event affected;
> Potential: how likely is it that the event will cause bigger events;
> Credibility: how credible is the source.
Then I do `Credibility * cbrt(Magnitude * Scale * Potential)`
cbrt = cubic root
Maybe the formula could be improved but I was satisfied with the result, so kept it that way.
